You can do it like this:

def callMethod(Class c, String staticmethodname, args = null ) {
  args ? c."$staticmethodname"( args ) : c."$staticmethodname"()
}

println callMethod( String.class, 'valueOf', 1 )
println callMethod( Calendar.class, 'getInstance' )

You can certainly do it the java-way:

c.getMethod(staticmethodname).invoke(null);

Voila

void callMethod(Class c, String staticmethodname){
     c."$staticmethodname"()
}

class test {
  static someMethod() {
    println "me"
  }
}

callMethod(test, "someMethod")
