Is this is a bug or am i doing something wrong?

We changed a lot of stuff in the 1.7 update, so to update a 1.6 workspace to 1.7 you not only have to edit the forge version, but also the forge gradle version.

Change it from 1.0 to 1.1

Ok, i changed the dependencies to

dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.1-SNAPSHOT'
    }

but do i need to change the version too:

version = "1.0"

If i run this "gradlew setupDecompWorkspace" from the command terminal:

buildscript {
    repositories {
        mavenCentral()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.1-SNAPSHOT'
    }
}
allprojects {
    apply plugin: 'forge'
    minecraft{version = "1.7.2-10.12.0.982"}
    version = "1.0"
    archivesBaseName = project.projectDir.name
}
processResources {
    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'
        expand 'version':project.version, 'mcversion':project.minecraft.version
    }
    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
}

i got this error:

Thank you!! That helped!!
