Description

I ran the Groovyc Ant task to compile my classes within Gradle. My code uses the @Singleton annotation. The version I set in the classpath is 1.8.1. The following snippet shows the code I use:

def groovycClasspath = getGroovyClasspath().asPath + System.getProperty('path.separator') + getTestRuntimeClasspath().asPath
ant.taskdef(name: 'groovyc', classname: 'org.codehaus.groovy.ant.Groovyc', classpath: getGroovyClasspath().asPath)

ant.groovyc(destdir: getClassesDir().canonicalPath, includeAntRuntime: false, classpath: groovycClasspath) {
    getSrcDirs().each { srcDir ->
        src(path: srcDir)
    }
}

When I run this without the attribute fork: true I get this compilation error:

Not an ASTTransformation: org.codehaus.groovy.transform.SingletonASTTransformation declared by groovy.lang.Singleton

Running Groovyc as forked process works fine. The compilation finished without an issue. Somebody on the mailing list reported the same error except that he uses Groovyc in Ant.
