Can anyone help me to figure out this issue. Thanks for your support

Answer 1

That is an impressive list of dependencies, and apparently quite a big plugin.

Let's start with this: My recommendation is to simplify this list. There are several dependencies in there, that used to be used in Liferay 6.x, but are no longer there/supported in 7.4 - for example lucene, jackrabbit, etc.

You should typically not be dependent on portal-impl at all. You seem to instantiate a GroupImpl object for your test - I'd recommend to create a mock/dummy at most: Your own tests typically don't want to use too much of the implementation of the underlying platform. And while portal-impl is part of the portal's implementation, it's not made available to client code. You'll only access the implementation indirectly through portal-kernel.

Also, with this migration, you should check first if your customization is still required, or if you can utilize some of the new built-in features. Best case, you can get rid of your custom code and rather rely on something that the platform provides, that you don't need to maintain any more.

What exactly goes wrong is hard to say without the code. But the code should be fairly minimal.
