I have been trying to include an external library dependency to my mod by trying to shade it as written here: https://forgegradle.readthedocs.org/en/FG_1.2/user-guide/shading/

However when i add this to my build.gradle:

minecraft {
    srgExtra "PK:com/dependency my/mod/com/dependency"
}

 

and i do

./gradlew build

i get this error

FAILURE: Build failed with an exception.

* Where:
Build file '/home/minecraftProject/build.gradle' line: 56

* What went wrong:
A problem occurred evaluating root project 'minecraftProject'.
> Could not find method srgExtra() for arguments [PK:com/dependency my/mod/com/dependency] on root project 'minecraftProject'.

 

here's my build.gradle

 

// For those who want the bleeding edge
buildscript {
    repositories {
        jcenter()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
        
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.1-SNAPSHOT'
    }
    
}

apply plugin: 'net.minecraftforge.gradle.forge'


/*
// for people who want stable - not yet functional for MC 1.8.8 - we require the forgegradle 2.1 snapshot
plugins {
    id "net.minecraftforge.gradle.forge" version "2.0.2"
}
*/
version = "0.1"
group= "my.mod.package" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "ModName"
sourceCompatibility = 1.8 
targetCompatibility = 1.8

minecraft {
    version = "1.8.9-11.15.1.1722"
    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 allways work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = "stable_20"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.

srgExtra "PK: com/dependency my/mod/com/dependency"
}
configurations {
    shade
    compile.extendsFrom shade
}
dependencies {
    shade fileTree(dir: 'libs', include: '*.jar')
}

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

    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info' 
        expand 'version':project.version, 'mcversion':project.minecraft.version
    }
    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
    
}

 

 

how can i solve it? i've been searching all day but got no luck

Super duuuuper necro post, but for anyone who finds themselves here after trying the srgExtra line, it's been changed in newer versions of gradle (2.2-SNAPSHOT I know, but maybe even earlier).

Now instead of doing:

minecraft {
    ...
    srgExtra "PK: ..."
}

 

You have to do:

reobf {
    jar {
        extraLine "PK: ..."
    }
}
