Greetings all! I have been creating an API for my mod so that I can use it to create add-ons. I have been looking at code from Galacticraft and others in order to get Gradle to build the API into a separate jar. I have added a new task to Gradle called packApi but when I go to build I only get the main and sources jar, no API jar. Is there something I am missing?

 

Here's my build.gradle file:

buildscript {
    repositories {
        jcenter()
        maven { 
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.2-SNAPSHOT'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'
//Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.

sourceSets.main {
    java {
        srcDirs = ['src/main/java']
    }
    resources {
        srcDirs = ['src/main/resources']
    }
}


def mcVersion = "1.11.2"
def spVersion = "0.1.0"
version = "${mcVersion}-${spVersion}"
group = "net.coolsimulations.SurvivalPlus" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "SurvivalPlus"

sourceCompatibility = targetCompatibility = "1.8" // Need this here so eclipse task generates correctly.
compileJava {
    sourceCompatibility = targetCompatibility = "1.8"
}

minecraft {
    version = "1.11.2-13.20.1.2454"
    runDir = "run"
    
    // 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 = "snapshot_20161220"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.
}


// Keep a list of main mod files/directories for easy jar packing
ext.coreFiles = ['net/coolsimulations/SurvivalPlus/core/**',
					'assets/sp/**']

// Keep a list of core files/directories for easy jar packing
ext.apiFiles = ['net/coolsimulations/SurvivalPlus/api/**']

dependencies {
    // you may put jars on which you depend on in ./libs
    // or you may define them like so..
    //compile "some.group:artifact:version:classifier"
    //compile "some.group:artifact:version"

    // the 'provided' configuration is for optional dependencies that exist at compile-time but might not at runtime.
    //provided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // the deobf configurations:  'deobfCompile' and 'deobfProvided' are the same as the normal compile and provided,
    // except that these dependencies get remapped to your current MCP mappings
    //deobfCompile 'com.mod-buildcraft:buildcraft:6.0.8:dev'
    //deobfProvided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

}

processResources {
    // this will ensure that this task is redone when the versions change.
    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    // replace stuff in mcmod.info, nothing else
    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'
                
        // replace version and mcversion
        expand 'version':project.version, 'mcversion':project.minecraft.version
    }
        
    // copy everything else except the mcmod.info
    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
}

task packApi(type: Jar, dependsOn: "classes") {
    // Jar will always be updated
    outputs.upToDateWhen {false}
    // Set the jar's base name
    baseName = "SurvivalPlus-API"

    from (sourceSets.main.output) {
        // Add necessary files, remove unnecessary ones.
        includes.addAll(project.ext.apiFiles)
        //includes.addAll('LICENSE.txt')
        excludes.addAll(project.ext.coreFiles)
        excludes.addAll('**/*.info')
        excludes.addAll('assets')
    }
}

 

Any help here would be appreciated.

you need to compile the jar by putting the jar:{} or something like that and then in that put the compile tags. I could never find a good explanation on how it works so I used hard coded version to compile the dependencies.

So I've added this above task packApi. However, I still don't get an API jar when I build.

jar
{
	// Add necessary files, remove unnecessary ones.
	includes.addAll(project.ext.coreFiles)
	includes.addAll(project.ext.apiFiles)
	includes.addAll('mcmod.info')
	//includes.addAll('LICENSE.txt')
}

 

I'm still trying to get this to work with no success. I've looked at Forestry, Tough as Nails and other build.gradle files but each one does this in different ways. Does someone know what I'm missing? My build.gradle now looks like this:
