Does your library use any Minecraft code?

Yes, i am extending net.minecraft.block.OreBlock and overwrite getExperience which returns a different int value depending on the block that calls the method, because I want that my ores drop xp too.

You know reobfJar doesn't prevent you from decompiling your mod and it doesn't completely obfuscate your mod, right?

It only reobfuscates what you use that is obfuscated in Minecraft.

Thanks! This makes sense and it also clears the question why my mod has to be mapped with fg.deobf

Maxi07 · August 17, 2020

This is what I get:

After I ran "gradlew --refresh-dependencies" and "gradlew genEclipseRuns eclipse" (which usually fixes this whenever I have this error with default minecraft code) a few times again and refreshed eclipse the problem stays.

DaemonUmbra · August 17, 2020

iirc that is usually fixed by refreshing the Gradle in the IDE, I'm not getting that issue

Yes this is what I experienced too. I ran gradlew --refresh-dependencies, gradlew clean, gradlew genEclipseRuns eclipse and refreshed my IDE three times more, but it did not solve my problem.

Then I did some research on forum topics I remember. At the last comment on each of this posts:

In particular this:

But the issues described at the end of the topics I quoted were not the one I have.

I dont think it is a problem the jar is reobf, because it gets mapped again via fg.deobf

DaemonUmbra · August 19, 2020

Running the command doesn't refresh the project in your IDE

Maxi07 · August 19, 2020

Yes, I know. I run gradlew --refresh-dependencies, then gradlew genEclipseRuns eclipse, and then I refresh my IDE. This is what I have done five times

What about this?

Maxi07 · August 19, 2020

I may found a solution:

The error was: Source not found

So I thought: Where could eclipse find the source? Only IntelliJ has a decompiler - I am using Eclipse.

And then I realized: I have the source on my hard drive! So I clicked on "attach source" and selected the src folder of my lib mod, and it worked.

However I am not sure this is the right way to fix this problem.

Can you give me screenshots of how you're refreshing the project in your IDE?

Maxi07 · August 21, 2020

I go to my project, right click and then click refresh. And usually I right click and click refresh on "referenced libraries" to

DaemonUmbra · August 21, 2020

You don't have the project registered as a Gradle project.

Go to Properties -> Project Natures -> Add -> Gradle Project Nature -> Apply and Close

Then Right Click -> Gradle -> Refresh Gradle Project

Maxi07 · August 21, 2020

Thanks, I will do as so as possible. I thougt I have to select general project because I already run the gradlew eclipse task.

Howerver, I have already clicked „attach source“ and selected the src folder of my other project. What should I do now?

Maxi07 · August 24, 2020

I fused my source code to a new blank mdk (to make sure all mdk file are up to date) and run .\gradlew genEclipseRuns in PowerShell. And then I imported the folder as "existing gradle project" in eclipse. (I did this for both projects, and I also build a new jar of my lib mod with gradlew build)

It does still not work. Here are the build.gradle files of both mods:

Also my problem is bit different now:

"Reffrecend Libaries" is now called "Project and External Dependencies", I think it is because it's now a gradle project instead of a normal java project

Are you using IntelliJ? I heard it has a build-in decompiler.

DaemonUmbra · August 25, 2020

I've recently learned that this was broken some time ago and I apparently just never noticed because intellij has its own decompiler to cover missing classes

Maxi07 · August 25, 2020

So, do you have any idea what I should do now? I think I have to get the source inside the jar (or something like this). Or is this still a forge bug?

Maxi07 · August 28, 2020

Maybe a multi build project will be easier and work?

Edited August 28, 2020 by Maxi07

Maxi07 · August 29, 2020

I think, now I have finally got the solution!

After I saw the topic "[1.14.4] How add JEI to own mod?", I focused on trying to find out how other mods do this.

The problem is clear: eclipse has found no source code. And I think this is not a bug, there is just no source code.

As far as I know, the faltDir behaves like a regular maven repository. At any mod I have looked (forge too), there is either a [jar name]-sources.jar (it is like the regular jar, but every .class file is the .java file) or the jar not only contains the .class file, but also the .java files. For example the mezz.jei repo at https://dvs1.progwml6.com/files/maven/

Lines from my build.gradle:

// The mappings can be changed at any time, and must be in the following format.
// snapshot_YYYYMMDD   Snapshot are built nightly.
// stable_#            Stables are built at the discretion of the MCP team.
// Use non-default mappings at your own risk. they may not always work.
// Simply re-run your setup task after changing the mappings to update your workspace.
mappings channel: 'snapshot', version: '20200723-1.16.1'
// makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.

// accessTransformer = file('src/main/resources/META-INF/accesstransformer.cfg')

// Default run configurations.
// These can be tweaked, removed, or duplicated as needed.

The is the comment "an Srg named sources jar is made by default". The fact that it is srg named should not matter, because it gets mapped. But the fact that a [jar name]-sources.jar is created is interesting.

If I were right right, I would just have to find this [jar name]-sources.jar.

And is where I need your help. Where is the sources.jar? Or do I have to add makeObfSourceJar = true (maybe the default is not working)

I'm going to back up here a little bit, to ensure that I'm understanding the goal correctly.

You want to add your own library as a dependency of your mod. But you don't necessarily want to be able to edit both the library and the mod at the same time. Building the library, and adding it in via gradle so it is available to the mod is sufficient?

Maxi07 · August 29, 2020

Yes, but actually now it's all about finding the sources.jar

Ommina · August 29, 2020

OK. In the build.gradle for the library, at the bottom, there is a section for 'publishing'. Within that section is:

repositories {
    maven {
        url "file:///${project.projectDir}/mcmodsrepo"
    }
}

Make note of the location. Or change it to something you like better. Or change it AND make note of it.

I have to do a bit of hand-waving here, as I understand you are using Eclipse, and I don't know the Eclipse way of doing things. In IntelliJ there is a Gradle panel with a publishing section, command named 'publish'. Publish the library using this command. That will put the library into what amounts to a local Maven repository.

In your mod, ADD that location to the mod's repositories section, keeping in mind you won't be able to use ${project.projectDir}. (This is why you might want to change it to a known convenient location.) THEN, under dependencies,

compile fg.deobf("[path to library jar]")

and that's it. The path matches how it appears under the mcmodsrepo folder.

Maxi07 · August 29, 2020

This has nothing to do with the sources.jar (I am already using a flatDir repo)!
