Description

Trying to execute a Groovy Test Case using the Groovy Ant Tasks fails because it is complaining about a missing main() method:

groovy.lang.MissingMethodException: No signature of method: org.guilder.plugin.PluginTest.main() is applicable for argument types: ([Ljava.lang.String values: {[]}
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:54)
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:59)
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.invokeMethodN(ScriptBytecodeAdapter.java:169)
at org.guilder.plugin.PluginTest.invokeMethod(PluginTest.groovy)
at org.codehaus.groovy.runtime.InvokerHelper$2.run(InvokerHelper.java:426)
at org.codehaus.groovy.ant.Groovy.execGroovy(Groovy.java:348)

This happens when I use Ant through the command line as well as using AntBuilder. This is the build.xml script I use:

project>
<path id="my.classpath">
<fileset dir="/Java/groovy/lib">
<include name="*/.jar"/>
</fileset>
</path>
<target name="run">
<taskdef name="groovy"
classname="org.codehaus.groovy.ant.Groovy"
classpathref="my.classpath"/>
<groovy src="org/guilder/plugin/PluginTest.groovy">
</groovy>
</target>
</project>

Executing the Script through: 'groovy org/guilder/plugin/PluginTest.groovy' it works fine.

Unfortunately I could not figure out how the Groovy Command Line tool does handle that otherwise I would created a patch.

Any ideas?

And by the way I ran into another issue with the Groovy jUnit Tests. Using the GroovyTestCase does fail on me because it cannot find the jUnit Test Case class. This is an issue for me because I fire up groovy without jUnit in its class path and then add it dynamically at runtime. Unfortunately the GroovyTestCase is attached to the class loader that stated Groovy and so I cannot add the jUnit archive on the same class loader level. Thus I get a No Class Def Found Error.

I don't have the fix for the Groovy Ant task, but I'll attach an Ant script that shows a way to work around the problem for the moment.

A sample Ant script that shows a way to call a GroovyTestCase from the Groovy Ant task.

Using a slightly modified version of Jim's script:

build.xml
<project name="groovytest" default="groovy-junit">
    <property name="dep-groovy.dir" value="C:/Downloads/groovy.codehaus.org/svntrunk-groovy/groovy-core/target/install"/>

    <taskdef name="groovy"
            classname="org.codehaus.groovy.ant.Groovy">
        <classpath>
            <fileset dir="${dep-groovy.dir}/embeddable">
                <include name="groovy-all-1.6-beta-1-SNAPSHOT.jar"/>
            </fileset>
            <fileset dir="${dep-groovy.dir}/lib">
                <include name="junit-3.8.2.jar"/>
            </fileset>
        </classpath>
    </taskdef>

    <target name="groovy-junit">
        <groovy>
           def loader = new GroovyClassLoader(getClass().getClassLoader())
           def testClass = loader.parseClass(new File('TestCase.groovy'))
           println testClass
           junit.textui.TestRunner.run(testClass)
        </groovy>
    </target>
</project>

And with this file:

TestCase.groovy
class TestCase extends GroovyTestCase {
    void testPlus() {
        assert 6 == 3 + 3
    }
}

I get this result:

Now calls the GroovyShell run method if a script isn't found. The special ant properties that the normal groovy task passes through via the binding are not available in this case.
