Question

I have folder test containing:

test
 -> groovy
     -> MyClass.groovy
 -> build.xml

The file MyClass.groovy contains:

class MyClass {
  void firstMethod(int i) {
    println i
  }

  String secondMethod(String txt) {
    return txt + "added text"
  }

  static void main(String[] args) {

  }
}

In my build.xml file I have (based on http://docs.codehaus.org/display/GROOVY/The+groovy+Ant+Task):

<target name="run-groovy-script-test">
    <groovy src="groovy/MyClass.groovy">
      <classpath>
        <pathelement location="groovy"/>
      </classpath>
        def aClass = new MyClass()
        aClass.secondMethod("asd")
    </groovy>
</target>   

Running the above gives:

 groovy.lang.MissingMethodException: No signature of method: MyClass.secondMethod() is applicable for argument types: (java.lang.String) values: [some-text]

Solution: Remove the src attribute – see below comments.

I know that I can specify a main method in the .groovy file which will automatically be executed using the above. But it could be nice to control which methods should be called directly.

Answer 1

//Declare a property in your ant.xml. 

<property name="myproperty" value=""/>

<groovy>
    //This will instantiate
    def aClass = new MyClass()

    //This will store the return value in the ant property
    properties["myproperty"] = aClass.secondMethods()
</groovy>
