Hi Andy :-)
You need to use normal Mojo semantics to get a hold of Maven
properties. There is no magical GString configuration to pre-load
the execution binding with Maven bits. Also, there isn't really a
need to use ant.echo() to print stuff out... so I'd recommending
using something like this instead for your simple example:
<snip>
/**
* Compiles Java Classes
*
* @goal compile
* @phase compile
*/
class JavaCompileMojo
extends GroovyMojoSupport
{
/**
* @parameter expression="${project.basedir}"
*/
File basedir
void execute() {
println('Hello Andy')
ant.echoproperties()
println("Basedir: $basedir")
}
}
</snip>
Cheers,
--jason

Hi Geeks
I just started to look into Maven 2 Groovy Plugin and I am already
stomped. It seems that I cannot retrieve Maven properties. I am
working on a Mac OS X 10.4.10 (Intel), Java 1.6.0-dp and using
Maven2 2.0.7.
I have this little groovy plugin:
package com.madplanet.m2
import org.codehaus.mojo.groovy.GroovyMojoSupport
/**
* Compiles Java Classes
*
* @goal compile
* @phase compile
*/
class JavaCompileMojo
extends GroovyMojoSupport
{
void execute() {
ant.echo( "Hello Andy" )
ant.echoproperties()
ant.echo( "Basedir: ${basedir}" )
}
}
and get this error:

Any ideas what I am doing wrong? I assume it is plain stupid but I
can't see it.
Thanks - Andy
