compileJava done before Datanucleus has enhanced classes

We're experiencing the same issue, running with: Gradle 1.0-milestone-1

That said both of the gradle commands listed above work for us. I could submit a test project (if useful), but it isn't substantively different.

As mentioned in the forum thread – I'm not seeing enhanced classes ending up in the .jar, this is easily verified by using javap to inspect them.

Is there a easy workaround?

I worked around this problem by using the datanucleus ant task. Below is how I updated build.gradle from the attached example.zip. With these changes, the test passes.

apply plugin: 'java'

repositories {
	mavenCentral()
}

configurations {
 jdo {
 	extendsFrom compile
 }
}
dependencies {
   compile 'org.datanucleus:datanucleus-core:1.1.5',
           'javax.jdo:jdo2-api:2.3-eb'
	jdo 'org.datanucleus:datanucleus-enhancer:1.1.4'
   testCompile 'junit:junit:4.7'
    
}

task jdoEnhance << {
	ant.taskdef(name: 'enhancer', classname: 'org.datanucleus.enhancer.tools.EnhancerTask', classpath: configurations.jdo.asPath) 
	ant.enhancer( dir: sourceSets.main.output.classesDir.canonicalPath.toURI().toString(), verbose: 'true') {
		classpath {
			pathelement(location: sourceSets.main.output.classesDir.canonicalPath.toURI().toString())
			pathelement(path: configurations.jdo.asPath)
		}
		fileset(dir: sourceSets.main.output.classesDir.canonicalPath.toURI().toString()) {
			include(name: '**/*.class')
		}
	}
}

classes.dependsOn jdoEnhance

Quote from http://www.datanucleus.org/products/datanucleus/enhancer.html#javac on running enhancer via annotations:
"Note that this works by waiting a period of time until all classes will have been compiled before invoking the enhancement step. We advise against using it, and better to use post-compile directly"

It looks like this is a limitation of running datanucleus enhancer via annotations rather than a gradle bug.
