How to find usage of an API method in all libraries in classpath?

Question

In Eclipse, I can easily find out where is a method used in all jars in the classpath. This is very useful because I am using a library whose API is not well documented. I always need to find out how an API method is used by the library itself.

But in IntelliJ, I can only find the usage in the source code of my own project. Is it possible to do it in all jar files in my classpath? How? Thanks.

Answer 1

You can use ctrl-alt-shift-f7 to adjust the scope of your find-usages search to Project and libraries.

In addition to your project files, it will search everything under External Libraries in your project pane - i.e. maven dependencies and the jdk.

However, for some reason I can't see any project libraries or global libraries under External Libraries, and as such they seem to be excluded from this search...

Answer 2

It appears to be a bug in IDEA that Find Usages doesn't search under module libraries. See my comment here for the details and vote for the issue to get it fixed sooner.
