How to Use Java to Call Ant JUnit Target

Why don't you call JUnit directly instead of trying to trigger it by Ant?

Why don't you call JUnit directly instead of trying to trigger it by Ant?

The reason is because the Gui built by Java code needs input from the user. So I was told that Java calls to Ant are somewhat easy to do and my JUnit testing project is built by ant so it seems to me logical to call Ant by the Java Gui to build the JUnit tests if that makes sense.

Thank you again for your reply. I have just been trying to get some pieces working. I have my Ant File which when called works fine. It goes through some JUnit tests and displays results.

Now I have been doing the basic setup from the link you sent me:

1. I have included all my three jars in the Eclipse Class Path and
created my java file.
2. In the java file I have included

File buildFile = new File("build.xml"); //I specified the exact
// location of xml file
Project p = new Project();
p.setUserProperty("ant.file", buildFile.getAbsolutePath());
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());//I have also tried
//using my exact targets from the Ant File

but I get a classnotfound error. I am now thinking it might be a classpath problem but I'm not sure? Thanks!

Hello,

I know you must have resolve your issue, but would like to share the resolution which might be helpful for someone else.

I also followed the link, and get the same classnotfound error, to resolve this i just added "ant.jar" and "ant-nodeps.jar" in my classpath. You can find these jars from your Ant/lib folder.

Hope this is helpful.

Thanks & Regards,
