Jenkins build system

Posted August 16, 201213 yr

I am working on a jenkins build system for my mods and I'm getting this error.

Someone know why it all works on windows but not on ubuntu server?

(I did chmod 777 the folder)

Please send me all the typo's you found, I'm from Belgium and I'm a little dyslectic and suck @ typing.

!! Please install either wine or astyle for source cleanup !!

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Need help with how to save data to a world!

If I remember correctly, I believe one of the rules, or maybe the faq, states something like, "This is not a java school, so make sure you know enough java."

I think it's clear that you might not know enough java to accomplish the task you have set out to do (or not, I can't really say based solely on these two snippets of code that you seemed to have selected and modified), but whatever the case may be, I find this rule, or suggestion, whatever it is, to be really stupid in some cases.

With that said, if you wish to save the data to the world, then with the code you have provided, I see no Event Handlers to do this with. I'm not sure if you know how to subscribe to event handlers with forge, but if you have your mod running in literally any capacity, then you should have done this with some methods in your main mod class container, otherwise how on earth is your mod gonna' work? So, I'm going to assume that you have gotten your mod to work in some capacity, if you haven't then please look into some more basic mod development, but I might also be able to help you out a little. Anyways, there is an event you can set up with one of your methods called "FMLServerStoppedEvent". I could have the wrong one, so you should probably look into the difference between "FMLServerStoppedEvent", and "FMLServerStoppingEvent", but either should work. The essential idea is to use this event with one of your methods, that way when the server stops, you can have a method called that will save all of your team data. Basically, you're going to want to write into your main mod class something that looks a little like this:
@EventHandler public void serverStopHandler(FMLServerStoppedEvent event) { //Code to save team data }And, in case you haven't done this yet, you're of course going to use the FMLServerStartingEvent to load this data into your mod, so you can do something similar to the above. But if you already have a method to load the mod data, then this shouldn't be needed.

Now, there are a number of mechanisms that you can use to save your data, one such method being to write the data into an nbtdata file and save it to the world folder, or writing it to some forgecaps and loading those forge caps through some other means. However, by far the simplest thing you could do would be to use a Buffer object to write and read data to and from a raw binary file saved directly to your server folder so it can be easily accessed. The first idea to accomplish this task would be to create a file that will contain your team save data if none exists, then open this file and either read your save data from it, or write your save data to it. Creating your file is as simple as importing the java.io.File class, creating a new instance of the file class with whatever name you want, for example, new File("teamsavedata.bin"), and using a FileOutputStream to write the bytes to the file, or if you need to read the bytes from the file, you should specifically use the java.io.Files class's Files.readAllBytes method. This takes a file path as one of its arguments. This can be acquired after you create an instance of java.io.File, you can simply use the toPath(), method on that instance. It is important that you use the readAllBytes method because it is not only very simple, but it returns the data in the file as a byte array, which fits the implementation of the ByteBuffer function. Now, the ByteBuffer function is what I think best for you to use to serialize (aka store as a series of numbers or bytes) the information contained within any simple class. NOTE: SIMPLE CLASS. Your Team class isn't exactly simple, but I will get into what you should do about that after I demonstrate serialization here. Now, the ByteBuffer class is very simple, but it does have some caveats that I will get into soon here. But for now, let's move on to actually serializing your data so that it can be written to your save data file.

First off, you're going to want to add the methods "toBytes", and "fromBytes" into your Team class. These methods should take a ByteBuffer as an output and input respectively. That should be all they need. Now, ByteBuffers work by reading data from a byte array and spitting out the data. I think this is going to be best shown with some code, so lets imagine we have some class we want to turn into bytes, and it has a boolean, a double, and a float as it's variables. If you were to implement the above into this class, it should look something like this.
public class MyClass { float floatValue; double doubleValue; boolean booleanValue; // Gets the required size of the Buffer to store our information // This can really be replaced with some big number like 1000 if you don't want to have to deal with size serialization // However, the above isn't exactly recommended if you care about good code private int getSize() { return 4 + 8 + 1; // Size of a float (4 bytes) plus the size of a double (8 bytes) plus the size of a boolean (1 byte) } // Takes all class values and writes them to a ByteBuffer so it can be written to a file public ByteBuffer toBytes() { ByteBuffer retValue = ByteBuffer.allocate(this.getSize()); retValue.putFloat(floatValue); retValue.putDouble(doubleValue); retValue.put(booleanValue ? 1 : 0); } // Takes the ByteBuffer created from the contents of the file and sets all class values accordingly public void fromBytes(ByteBuffer buf) { floatValue = buf.getFloat(); doubleValue = buf.getDouble(); booleanValue = buf.get() == 1 ? true : false; } }Now, it is important to note that the ByteBuffer function, although easy to implement, it is very primitive, and with more complex data types such as strings and lists, it can be much harder to use than the netty ByteBuf class. The ByteBuf class is practically the same as the ByteBuffer class, except it has much more versatility. You would probably want to use this class for handling your data as opposed to the ByteBuffer class. I just use the ByteBuffer class here because it is a bit easier to demonstrate and describe specifically in examples. If you want to use the ByteBuf class, you need to instantiate and instance of ByteBuf by doing something like Unpooled.buffer() if you are creating an empty buffer, and Unpooled.wrappedBuffer(fileByteArray) if you are creating a ByteBuf with a byte array already put into it. Now, I believe the ByteBuf class is intended to be used for networking serialization rather than file stream serialization, but it's just too good not to use here, so although this is a bit of an inappropriate usage of the class, things should still be fine. Simply just use ByteBuf in the same way as described for ByteBuffer above. Make sure to use the right methods when handling data.

With all that said, you should be practically done here and ready to write your code to handle saving and loading your custom data. You will have to take the liberty with how you are going to handle serializing your data. I will give you some quick pointers here for how to do that.

STRINGS
These guys can be a bit annoying to deal with, but the best way to do it is, if you are using a ByteBuf, to write the size of the string first, then write the characters of the string to the array, which can be done with the writeCharSequence method. String are implicitly CharSequences, so you shouldn't have to worry about casting, and use Charset.defaultCharset as your second argument. When reading the string data, read the integer first, which is the size of the string, then use the string size with the readCharSequence function. You might need to instantiate a new instance of String to convert a CharSequence to a string.

LISTS/ARRAYS
These can be serialized much the same way as strings, with the only difference being that you aren't serializing an array of chars, but an array of specific data types. Basically, read or write the size of the list to the ByteBuf, then iterate over either the size of the list and individually serialize or deserialize each object instance individually.

OTHER CLASSES
If there is another class that you wish to serialize or deserialize, then if it doesn't have the built in methods for converting to or from bytes, just find a way around storing them as data by any means. If you have no choice, then you will have to build your own functions to serialize and deserialize other classes you wish to use. Some classes may be convertible into arrays that can be serialize or deserialized, such example being UUIDs, which if I remember correctly, can be converted into an array of bytes through a built in function and such an array can then be serialized.

Hopefully you find this helpful enough to be able to figure out what you need to do now on your own. If you do not fully understanding something that I have mentioned here, then please use the tools at your disposal to understand it better. If you are still struggling and need some pointers or additional advice, please reply to the thread with any questions or concerns you may have. I did not go fully into detail here, but rather just provided some pointers on what to do. I will clarify again, if you do not understanding something here, do not be frustrated, as I didn't put nearly enough effort into this reply in order to fully describe the topic at hand.

Remember to pray before running your code. Little know fact, but all great programmers carry a bible, a cross, and some holy water just in case they run into any errors of biblical proportion that requires divine intervention in order to solve.

Please let me know if this helps or not.

How would I determine if a command being executed is the product of the "/execute" command?

UPDATE:

Okay, so I have a really good fix going on rn, but the problem still isn't exactly solved. Although the quick fix works well enough to be practical, it's not exactly perfect and can cause bugs. Basically, I just injected code at the start of the execute method of the execute command, as well as many others that search the argument list for the string "commands:onepunch" (the name of the super item that I don't want my friends to be able to have), and if it detects said string, it forces the function to return without doing anything.

This might sound like a foolproof method of preventing anyone from getting the super item, which it is, but the problem is that it's a bit too foolproof. Instead of the logic behind the practical obtainment of this item in reference to commands being something like, "You can't spawn in this item by any means unless you are the server owner", it turns it into something like, "You can't reference the item in ANY WAY in commands unless you are the server owner." This could cause some issues, like, for example, if I were popbob, and I were to run the command "/execute @e[type=sheep] ~ ~ ~ give popbob commands:onepunch", the code would run the execute command successfully, even though it detects that the super item is referenced because popbob, me, the server owner, is running the command. However, because it is still not able to differentiate between a /execute trigger for a command and a directly run command, even though I am the one who ran the execute command, it will fail once the /give part of it is passed to the sheep.

Although for all practical purposes I am happy with what I have so far, it still doesn't really work as intended, so I'll refrain from tagging this thread as solved in the hopes that somebody can come up with a solution to the specific problem at hand.

org.spongepowered.asm.mixin errors when trying to runClient in test enviroment

Okay, took a look. This might be helpful. This also might not be helpful. I'm not exactly sure what the issue is, but then again, with strange and unexpected problems, I'm not sure if anyone can be. Regardless, I will still do my best to help ya' out. First off, I don't think that the "caused by" error segment is really helpful for the context of the problem. Looking at the root error, the "Critical injection failure: " states that the Mixin injection function (that I'm going to hopefully assume is your function), addCustomEndBiomeMusic, is unable to find a method in the minecraft class with the specific name of "m_91107_", which takes zero arguments and returns an object of type net.minecraft.sounds.Music, which all matches with what should work in an srg environment. However, there are two issues that I have here. My first issue I have is that I'm not exactly sure you're in an srg environment. I noticed that when your environment loads the forge "mod", it loads a file with the name "forge-1.20.1-47.4.0_mapped_parchment_2023.06.26-1.20.1.jar". Now, this could mean two things. The first could be that you are in a MAPPED environment, specifically parchment, so when Mixin tries to find the method "m_91107_", it ends up failing because the loaded forge jar doesn't have srg mapped functions. If this case ends up being true, then the fix would be to simply just rename the method from "m_91107_" to "getSituationalMusic". If you are not in direct control over the addCustomEndBiomeMusic method, then you could also try remapping to an srg environment. If the parchment mappings are interfering with the getSituationalMusic method, which I'm not sure why they would be doing that, then you might want to try using the parchment mappings in reference to the getSituationalMusic method, if that even means anything at all. Now, keep in mind that I have literally never used parchment, and I don't even know wth it really is other than what the website described as a mod that "provides the Librarian gradle plugin to allow the use of Parchment mappings in a Minecraft Forge development environment." I don't know what this means, or how exactly this is accomplished, so it's VERY possible that I could be misinterpreting this situation.

Assuming that I am misinterpreting the situation or that the suggested fixes above do not work, then my next issue would have to be the fact that Mixin references a file named "blueprint.refmap.json" for its mappings. I also noticed a mod being loaded named "blueprint". This gives me the impression that the blueprint mod provides a mapping file for Mixins to use to make it cross compatible between normal minecraft forge mappings and parchment mappings. If anything else, then maybe you provided the blueprint.refmap.json file. Idk, I'm literally just guessing as to what the problem is at this point. But assuming that this is true, then it might be pertinent to know that after carefully looking through your log file, it states the following: "Found 2 mods for first modid blueprint, selecting most recent based on version data". After which, it then states, "Selected file blueprint-382216-6408581_mapped_parchment_2023.06.26-1.20.1.jar". Now, after looking even more carefully, it seems as though you might have put blueprint in your gradle dependencies when I'm not sure if it should really need to be put in there if you have a dependency folder, causing the exact same mod to load twice. Now, the problem shouldn't be that the mod is loading twice (although you might want to look into that), but the problem could be that you might have an incorrect version of blueprint. If this is the case, then, well, you should know what to do (get the right version).

There is one more thing worth considering for the last suggested issue. If blueprint has nothing to do with parchment, or is not equipped to handle parchment related mappings, or if there is some mechanic of parchment and how it crosses its mappings that the blueprint refmap cannot handle, then you might want to try just supplying your own refmap specific to the mappings that should work with your environment to your Mixin. Don't ask me how to do this, because I have absolutely no idea.

Now, this isn't another suggested fix for you, but I do believe it would significantly help you to understand the issues at hand here. If at all possible, get your hands on the blueprint.refmap.json file and take a good look at it. Make absolutely sure that the refmap matches the loaded version of the forge jar that you have, and if you aren't using forge mappings, then first off wth are you doing???, but secondly, just make sure that the blueprint refmap matches the environment mappings that you have. Use a java decompiler if needed.

Whatever the case may be for the issue at hand, I am not well equipped to deal with it. Ultimately, this issue seems more to be an environment issue rather than a general issue that any well rounded person could solve. Specifically, your issue depends on factors that you particularly control in your environment, which means that solving it requires mastery of these factors. Although you provided more information than most people would, and although you did this as concisely as humanly possible, in the end it doesn't really matter, because you can't fully describe every little detail without ending up like me, and I'm not even capable of coming close to explaining everything I do. These little factors, like implementing Mixin, adding parchment mappings, using 1.20.1 forge, using Eclipse Adoptium, and many more, are just going to be further testament to the fact that, and I know you probably don't want to hear this, the person who is most likely to solve your problem is going to be you, because you are the only person that understands your environment better than anyone else. Now don't get me wrong, I'm most DEFFIDENTLY not saying that you shouldn't post to forums for help with these more complicated problems, because you should; although you are unlikely to get a concise and precisely accurate answer as to the solution for the problem at hand, there is a chance that posting can get somewhere, or even provide the chance for others to possibly give another perspective for your issue that will help you end up at the best solution possible. And when you solve your problem, you can come back to the forums and tell everybody, that way when others come upon your situation, as strange as the situation may be, they can know what to do.

With that said, please let me know if anything here gets you anywhere, even if it isn't helpful.

Also, sry for constantly making massive text walls.
