Error when trying to run Minecraft client in Java Eclipse

I don't know if this is an error many other people are having, but I have been trying to learn how to code Minecraft mods using Java Eclipse from a book I purchased, and I recently finished the section that involves making new blocks, items, and textures for said blocks and items. I've followed what the book said, and tried to run the client only to have it crash with the error ("AL lib: (EE) alc_cleanup: 1 device not closed
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release") at the 7/7 stage on the loading screen. I have also had to reinstall the whole modding setup that allowed everything to work before, including the relevant Java versions that allowed Java Eclipse to work because of an error that would not let Eclipse open, caused by some of the older java versions being deleted. After I got everything working with Eclipse again, I copied the "src" file in the forge folder were the mods being worked on were stored to the new forge directory and everything seemed to be working well, until I tried to run the client.  I was also using Java Eclipse Neon before and I am now using Java Eclipse Oxygen now  (provided that helps at all). I am mainly asking here, because I have tried to troubleshoot the issue myself by looking up the error, but with no success. I would be very happy if anyone knows what the issue is and how to fix it. I'm sorry if I did a bad job of explaining anything.

 

 

 

Here is the console output in Eclipse.

"AL lib: (EE) alc_cleanup" isn't your problem. A clean exit will display that message too.

 

In addition to the above, use a god damn spoiler tag.

I went to the site that you suggested, it proofread some of the code, then I copied over the changes, but I still seem to be having the same issue. Thank you for telling me about the json syntax checker though, I'll definitely have to save that one to use for any later json files I make.

I apologize, I am not regularly post forum posts, so I did not think to put the console in a spoiler tag. My recent edit should fix that.

Yes, Things have changed since 1.8. A lot. I might be able to help you with the basic stuff in about an hour or so once my cake is out of the oven. I desperately need a distraction from my own project right now. Write me a pm should you be interested.

 

And do you still have the exact same error?

It gave the same error, and is this a case where I have no choice but to update to a newer version? If so, what version would involve the least amount of changes to the code, as I am still semi new to this?

Too be honest I have absolutely no idea. I quit shortly after 1.8 came around because the new item and block texture system meant that updating my old mods would have been an absolute nightmare. I only returned yesterday, but from what I can tell a lot.

However, should you be interested I can format and upload my own notes on developing for 1.12 somewhere. I try to make them as easy to understand as possible because that usually helps me a lot to remember them. Right now they cover most of the basics.

Just stay away from the part that messes with preloading dimensions. It involves an unhealthy amount of hacks, unoptimized + outdated code and I think some byte code injection. Have never finished prototyping that in 1.7 and haven't gotten far enough in 1.12 to rewrite it.

 

Now that I am getting used to some of the new systems they have introduced and figured out how I could reuse certain classes I have to admit that the newer versions aren't as bad as I thought they would be when I quit. Once you have the basics setup you can add new Items and Blocks with just a few simple Json files.

If you don't mind a slightly obsolete method of doing things

https://github.com/Draco18s/ReasonableRealism/blob/master/src/main/java/com/draco18s/hardlib/EasyRegistry.java

https://github.com/Draco18s/ReasonableRealism/blob/master/src/main/java/com/draco18s/hardlib/client/ClientEasyRegistry.java

These classes are proxy/client proxy.

It makes registering blocks and items very similar to how it was done in 1.7

Also note that these lines are just a reference back to the main mod class so that static methods can be used instead.

Those are a common and a client proxy so that the server only registers the item while the client can use super to both register the item and assign a Model to it.

 

Since when are common/client proxy classes outdated? I use them to have different init functions. :worried:

They aren't. The obsolete part is the GameRegistry. They've been deprecated in favor of the Registry<T> events.

I guess my main question at this point is where does the error lie and how could it be fixed? I'm unsure if the error is being caused by trying to load the new textures on to the new items/blocks, since they worked before, although having the black and purple default texture, or if the error is due to something in my modding setup not being compatible with something else in the setup for 1.8.

I mean, if this is possible to fix while still using 1.8, I would prefer to do that for now, at least until I'm done with the book. After that though, I might start looking into how things are done in some of the newer versions.

Ohhh. Totally ignored the part that still used GameRegistry. Thought your example had already switched to the new system.

Nope. I need to update to that method, but I haven't gotten around to it yet.

Well, I tried to set up a modding environment for 1.12 in an attempt to fix this issue, but when I type "gradlew setupDecompWorkspace eclipse" (which has worked in the past), or just "gradlew setupDecompWorkspace" it says that recompileMc failed and gave a way to possibly fix it, which I attempted to fix with no results. I don't know if it is because I don't know enough about how things work with Minecraft modding yet, but things seem like they are being difficult for no reason. Anyways, if anyone has any idea for me to try to fix the issue I am having with 1.8 especially, or 1.12, then please let me know. Also, thank you for your help so far.

Gradle is awesome...when it works.

 

Try to delete your C:\Users\YOUR_USER_NAME\.gradle folder (it's hidden) and then download the recommended mc forge version for 1.12 and run these two commands:

gradlew.bat setupDecompWorkspace

gradlew.bat eclipse

(Assuming you are on windows)

Should you still get an error tell us exactly when you got the error, what system and java version you are running on and what the log says.

As Forge has grown, the setup requires ever more RAM. You might need to set a cmd-line option to offer more RAM to the JVM. However, you should not make promises that your hardware can't keep. Some people have success by reducing the value in the option, protecting the job from trying to use RAM that isn't there.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

Sorry for taking so long to respond to this, as I have been quite busy. Currently I have a folder called "forge" for 1.8 and a folder called "forge1.12" for 1.12 on my desktop. Is there anything you can think of that could be conflicting between those two when I am trying to set up the 1.12 version, and can you have 2 workspace folders available to edit, though not open at the same time, and still have it work?

 

Aside from that, Jacky, I tried doing what you said about finding and deleting the .gradle folder. I then installed the recommended version of forge for 1.12, and installed it. I then typed the command gradlew.bat setupDecompWorkspace in the folder "forge1.12" and the error it gave is below. Also, I am using windows.

I then also typed "gradlew.bat eclipse" and this is the error that that gave.

I know that it says what's wrong, but my question is how exactly should I go about fixing it so that I don't mess something up in the process. Also, Jacky was wanting me to send the error output if there was one, which there was.
