Getting Groovy's Grape Going!

Question

I've tried to use the new Groovy Grape capability in Groovy 1.6-beta-2 but I get an error message;

unable to resolve class com.jidesoft.swing.JideSplitButton

from the Groovy Console (/opt/groovy/groovy-1.6-beta-2/bin/groovyConsole) when running the stock example;

import com.jidesoft.swing.JideSplitButton
@Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,)')
public class TestClassAnnotation {
    public static String testMethod () {
        return JideSplitButton.class.name
    }
}

I even tried running the grape command line tool to ensure the library is imported. Like this;

 $ /opt/groovy/groovy-1.6-beta-2/bin/grape install com.jidesoft jide-oss

which does install the library just fine. How do I get the code to run/compile correctly from the groovyConsole?

Answer 1

There is still some kinks in working out the startup/kill switch routine. For Beta-2 do this in it's own script first:

groovy.grape.Grape.initGrape()

Another issue you will run into deals with the joys of using an unbounded upper range. Jide-oss from 2.3.0 onward has been compiling their code to Java 6 bytecodes, so you will need to either run the console in Java 6 (which is what you would want to do for Swing anyway) or set an upper limit on the ranges, like so

import com.jidesoft.swing.JideSplitButton

@Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,2.3.0)')
public class TestClassAnnotation {
    public static String testMethod () {
        return JideSplitButton.class.name
    }
}

new TestClassAnnotation().testMethod()
