Subject MOJO/plugin use of TestNG annocation results in an exception
Date Fri, 20 Jan 2006 18:50:34 GMT
Hi,

 

I am invoking a TestNG test from within a plugin.  The test class has a
java 1.5 language annotation when the exception took place.  Changing
the test class to a TestNG javadoc tag/annotation allowed the tests to
run without experiencing an exception.

 

I checked to make sure the annotated interface could be found at some
point.  It was!  It is in the dependent jar - TestNG.

 

Anyone experience this before?  Any suggestions?

 

Thank you, Michael

 

 

Code:

 

        ClassLoader classLoader = this.getClass().getClassLoader();

        getLog().info(classLoader.getClass().getName());

 

        try {

 
classLoader.loadClass("org.testng.annotations.Test");

 
getLog().info(org.testng.annotations.Test.class.getName());

        } catch (ClassNotFoundException e1) {

                                    getLog().error(e1.getMessage());

                                    e1.printStackTrace();

                                    throw new
MojoFailureException(e1.getMessage());

        }

 

 

Result:

...

[INFO] org.codehaus.classworlds.RealmClassLoader

[INFO] org.testng.annotations.Test

...

 

 

 

Code:

                        try {

                                    getLog().info("testing class loading
of 'org.testng.annotations.Test'");

                                    Class otat =
Class.forName("org.testng.annotations.Test");

 
getLog().info(otat.getClass().getName());

 
getLog().info(otat.getCanonicalName());

                        } catch (ClassNotFoundException e) {

                                    getLog().error(e.getMessage());

                                    e.printStackTrace();

                        }

 

...

            TestNG testng = new TestNG(xmlSuite);

            testng.setTestJar(jarFilename);

            testng.setSourcePath(srcPath.getAbsolutePath() + ";" +
testPath.getAbsolutePath());

            testng.setOutputDirectory(metadataDir.getAbsolutePath() +
"/testNG");

            testng.setVerbose(1);

            testng.setGroups("Preferred");

            testng.run();
