How to make a mod dependant of another

[Enderlook]

 

I've made two mods:

• Extracraft Core: this mod has my custom classes which inherit from Item and Block.
• Extracraft: This mod import that classes and with them creates items and blocks.

I made this because I've planned in the future to make several mods and I don't want in each one have to make that classes, so I want to have a "core" mod which is used by all of them.

 

The strange this is that when I try to compile the mods it produces to jars:

• Extracraft-1.0.jar
• Extracraft-1.0-sources.jar

And if I drag the first file in the mod folder, both mods appear in Minecraft, so:

• It seems that the second file is useless.
• "Physically" in the mod folder there is only 1 jar, but "virtually" in the Minecraft mod button you can see 2 mods. So it seems that both mods get fussed in the same jar file.

 

 

I compile them using "gradle.bat build" and in the build.gradle I wrote:

version = "1.0"
group = "net.enderlook.extracrafcore"
archivesBaseName = "extracraftcore"

If I let the values as default (com.example.modid) it also works but the file change of name...

 

So my questions are:

1. Is fine my idea of split the "common" code between my mods into a "core/lib/whatever" mod? Or is it a bit stupid/lazy?
2. How can I split that .jar into two .jar (one for each mod)?
3. What is the usage of Extracraft-1.0-sources.jar?
4. If when I use "gradle.bat build" gradle compile all my mods, What would happen if I have a lot of mods? Is there a way to as gradle to only compile an specific mod?

 

Thanks in advance!

Yes, because it contains unobfuscated source code. Hence the -sources in the file name

Yes, because that's what your build.gradle file told gradle to do.

This is how I split my jar file:

I've tried to do the same as you but it isn't working::

version = "1.0"
group = "net.enderlook.extracraftcore" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "extracraftcore"
  
// [...]

task extracraftcore(type: Jar) {
    baseName = 'extracraftcore'

    from('etc/extracraftcore') {
        include '*.info','pack.mcmeta'
        expand 'version': '1.0', 'mcversion': project.minecraft.version
    }

    from zipTree(jar.outputs.getFiles().getSingleFile()).matching {
        include 'net/enderlook/extracraftcore/**', 'assets/extracraftcore/**'
		exclude '**.xcf', 'net/enderlook/extracraft/**', 'assets/extracraft/**'
    }
}

task extracraft(type: Jar) {
    baseName = 'extracraft'

    from('etc/extracraft') {
        include '*.info','pack.mcmeta'
        expand 'version': '1.0', 'mcversion': project.minecraft.version
    }

    from zipTree(jar.outputs.getFiles().getSingleFile()).matching {
        include 'net/enderlook/extracraft/**', 'assets/extracraft/**'
		exclude '**.xcf', 'net/enderlook/extracraftcore/**', 'assets/extracraftcore/**'
    }
}

extracraft.dependsOn('extracraftcore')

task releaseJars(type: Copy) {
    from extracraftcore
	from extracraft
    //one of these lines crashes it?
    rename '-(.*)jar', '.jar'
    rename '-(.*)zip', '.zip'
    into '.'
}

task fullBuild(type: Delete) {
    delete jar
}

fullBuild.dependsOn('releaseJars')

Also, I've noted something strange on your mod that I don't understand: Your "mcmod.info" is the default of forge (examplemod) (In my mcmod.info I've two dictionaries {}, one for extracraft and another for extracraftcore ).

I pull the mcmod.info file from a different directory (that isn't on github).

 

Not sure why it's not working off the top of my head. I know I had to mess around with things for a while before it worked. What you have looks just like what I have.

I think I get the same problem, but the output succeeds anyway. Check your build folder.

 

Edit:
May be that you need to run the right gradle command.
gradlew build fullBuild

I suggest including a version number like I do:

https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/build.gradle#L154
The variables are defined towards the top:

https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/build.gradle#L13-L22

That will let the output file have its version number in it.

Ok, I've changed just to try:

baseName = 'extracraftcore-1.0'

baseName = 'extracraft-1.0'

And when I run "gradlew.bat build fullBuild" I get this error:

FAILURE: Build failed with an exception.

* What went wrong:
Failed to create MD5 hash for file C:\Juegos\Minecraft\Codding\forge-1.12.2-14.23.4.2705-mdk\.gradle\2.14\taskArtifacts\cache.properties.lock.

And then it says in Spanish something like "The process doesn't have access to the file because another process has blocked a part of the file".

I don't know what to do

Never encountered that error before.
