[GROOVY-3413] Grab doesn't dependencies available for compilation when class loaded via GroovyScriptEngine

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Won't Fix
• Affects Version/s: 1.6
• Component/s: Grape
• Environment: MacOS 10.5, junit tests run in maven build
• Assignee: Unassigned

Description

I have a test script which uses Grab ...

@Grab(group='commons-primitives', module='commons-primitives', version='1.0')
public class GrapeClass {
	
 def createEmptyInts() { new ArrayIntList() }

 def verify() {
   def ints = createEmptyInts()
   ints.add(0, 42)
   assert ints.size() == 1
   assert ints.get(0) == 42		
   return "ok"
 }
}

which is successfully loaded via a GroovyClassLoader as follows

public class GrapeTestCase extends GroovyTestCase {
	void testGrape() {	
		def loader = new GroovyClassLoader(this.class.classLoader)
		assert loader.parseClass(
			new File("target/test-classes/sites/thirdparty/plugins/GrapeClass.groovy"))
			.newInstance().verify()=="ok"
	}
}

but not via a GroovyScriptEngine ...

public class GroovySriptEngineGrapeTestCase extends GroovyTestCase {
	void testGrape() {	
		GroovyScriptEngine gse = new GroovyScriptEngine("target/test-classes/sites/thirdparty/plugins/");
		Class<?> clazz = gse.loadScriptByName("GrapeClass");
		assert clazz.newInstance().verify() == "ok";
	}
}

This final test cases throws the error

       ... 34 more

Which seems to indicate that the class can't be found via the classloader. If I dump the classpath of the classloader then I see that the jar is on the classpath ...

log.debug(this.class.classLoader.classPath.join(":"))

outputs
