Externalize Common Gradle Functions

Content of helpers/common-methods.gradle:

// Define methods as usual
def commonMethod1(param){
    return true
}
def commonMethod2(param){
    return true
}

// Export methods by turning them into closures
ext{
    commonMethod1 = this.&commonMethod1
    otherNameForMethod2 = this.&commonMethod2
}
And this is how I use those methods in another script:

// Use double-quotes, otherwise $ won't work
apply from: "http://myhelpers.com/helpers/common-methods.gradle"

// You can also use URLs
//apply from: "https://bitbucket.org/mb/build_scripts/raw/master/common-methods.gradle"

task myBuildTask{    
    def myVar = commonMethod1("parameter1")
    otherNameForMethod2(myVar)    
}
