People,

I did a plugin that writes junit test cases from java source code.

By now, I'm starting to use reflection in my code, but the plugin can't find the classes in the java project being tested!

Is there a way to use the selected project classpath in my plug-in? How??

best regards

No, your plugin can't see stuff from a workspace through reflection, as
it hasn't been loaded into a class loader.

To manipulate a java project in a workspace from your plugin, you need
to use the JDT APIs. Like using AST to create the JUnit classes, etc.

Please have a look at the JDT Plug-in Developers Guide, and see

Hi Paul,

thanks a lot for introducing me to JDT.
I find out that many things I implemented was already done there.

A question: does JDT AST parser provide the execution paths of a method?
