Hi @arunkumarmsks, it looks like you’re following along with this tutorial? Is that correct? Just trying to understand the context of the question you’re asking.

If you are following the tutorial @rwhitbeck mentioned - that class is basically a hack (sorry I’ll use that word to describe it) to recreate atlassian-plugin.xml’s into a single location.

One of the problems with atlassian-spring-scanner is that if an import is annotated with @ComponentImport in one class(class A) but not in another(class B) - it still gets imported (which it should be) into both class A and B. But when you then remove class A - the import isn’t done anymore and class B breaks. This looks like to be a workaround of that by having a single trusted record.
