[1.7.10] [SOLVED] Linked source does not work with gradlew build?

Elix_x · October 26, 2015

Hello, today i met some problems with building my mod:

My mod depends on core mod, which is developped in different workspace. For ease of changing core mods' code, i link core mods' src/main/java to project using linkied sources.

When i try to build my mod, i get this in console:

C:\my\mcmodding\mods\Colourful-Blocks>gradlew build

Apearently, gradle does not read linked classes? What can i do to avoid that?

Because when developping several mods simulatenously, and applying changes to core (because there's common classes), it will become very problematic syncing core code in multiple places...

Thanks for help!

If you have any questions - just ask!

shadowfacts · October 26, 2015

Unless you include your core mod via Gradle (easiest would be using a compiled jar and potentially shading it), Gradle has no idea if they exist.

Unless you include your core mod via Gradle (easiest would be using a compiled jar and potentially shading it), Gradle has no idea if they exist.

I understand that, but how can i say to gradle "grab more class files there"? Or i could use shaded jar method, but i don't know how to do this either.

shadowfacts · October 26, 2015

I'm not sure about the first method, but the easiest way is probably to shade your dependency. This is the official tutorial. You will only be able to shade your library mod into your actual mod if the library mod doesn't have an @Mod class.

Elix_x · October 27, 2015

First of all, coremod has classes, that my mods use to interact with each other in case they are installed.

Second of all, coremod is a mod and not just common classes, as for their functionality it has to setup things at runtime.

So i cannot use shading, because if i use it - minecraft will just crash, because

new mod1.lib.CommonClass()

is not

new mod2.lib.CommonClass()

.

I'll try to google for other solutions myself, but anymore ideas?

Elix_x · October 27, 2015

I succesfully did it! And it is pretty easy actually.

Here's little tutorial of how to add eclipse's linked sources to gradle:

-Now open build.gradle file of project.

-In

dependencies

add

	compile files("linkedSourceClassFilesDir"){
	 builtBy 'compile'
}

and replace

linkedSourceClassFilesDir

with folder containing compiled class files of linked source. In case when linked source is another mod, they are in

modDir/bin

. In my case, it is

C:/my/mcmodding/mods/excore/1.7.10/bin

.

-Somewhere else in build.gradle (in the end, or just below

dependencies

) add this line:

task compile {}

.

-How does this work?

--In dependiencies you tell gradle, to take files in

linkedSourceClassFilesDir

and compile them by running task

compile

--

task compile

line is compile task itself which is going to be run to compile files.

--But because we take already compiled class files, there's no need of doing anything with them. That's why

task compile

is empty.

-Here's example of what you should end up with:

dependencies {
compile files("C:/my/mcmodding/mods/excore/1.7.10/bin"){
	 builtBy 'compile'
}
}

task compile {}

Thanks for help everybody!

You could also add the compiled library mod jar as a compile time dependency and just not shade it.

I could... And it is what i tried first... But exporting jar every time core mod is update... I'm too lazy for that ...

Bit of a bump here, but you you mind providing an example of this? I'm working with sqlite-jdbc and I've tried a few ways to compile it with a mod unsuccessfully so far, it downloads from maven repos if I include it in the buildscript dependencies but beyond that I'm not sure where it downloads to; I've no issue with Java but Gradle is a new one for me. I do also have the sqlite-jdbc jar file but again, gradle is alien right now.

Using the above from Elix compiles and runs but the server crashes as soon as it hits the code requiring JDBC with a classNotFound exception, as expected really.. And of course the mod works if I include JDBC in the Mods directory on the server but I'm trying to avoid that.

What i was doing is compiling required dependency which was developed in separate folder.

What you is trying to do is to compile optional dependency. Independently of how you compile it, you either make it required or use reflection and

@Optional

annotations everywhere where referencing it.

http://forgegradle.readthedocs.org/en/FG_1.2/user-guide/shading/

If you do shade it into your jar, you need to read the project's license and make sure you have permission to redistribute it before doing so.

@Optional

wouldn't work because sqlite-jdbc isn't a mod.

Yeah luckily I'm able to distribute this under their terms for non-profit reasons and I think maybe a reference to their original jar file in the manifest. I've managed to shade it in using a method (given a lot of reading) that was actually fairly simple and obvious once you showed me it:

Taken and studied from the link provided:

configurations {
shade
compile.extendsFrom shade
}

dependencies {
shade 'org.xerial:sqlite-jdbc:3.8.11.2'
}

jar {
configurations.shade.each { dep ->
	from(project.zipTree(dep)) {
		exclude 'META-INF', 'META-INF/**'
	}
}
}

The only issue I have now is that the server acts as though it's not there; I'm assuming that since the shading happens at the reobfuscation period that references to sqlite-jdbc use the regular package names whilst developing so I'm not sure where to stand with this.. Thanks for the poke in the right direction so far, though
