How to find out from which jar a class is imported?

Question

Java

Suppose class A code uses class B, whose definition is in a third-party jar library that we import into class A. How can I find out the full path to the jar file from which this class B is imported if, among other things, I import classes C, D and E?
For example, in Eclipse, in the BuildPath of the project, there are a ton of jar files and, let's say, they are named in such a way that looking at them it is impossible to understand by the package name whether the corresponding class is inside or not

Answer 1

In Eclipse, you can try to simply go to the class code (Ctrl+Click), which will result in a window with a message that means "sources for the class from jar not found" with the full path to the jar file, taking into account the order of appearance of the libraries in the classpath.

Answer 3

I came across in this context a mention of a certain Tattletale tool :
Perhaps this will help.
