Q:

How to make eclipse "File Search" to also search inside source jars containing some text?

I am working on a (Java) project in which I have many jars which have a source-jar file attached.
Is there any way to make the eclipse "File Search" search for Java files (and txt, xml etc. for that matter) containing some string literal inside these source jars, not just in the project folder?
Or is there any plugin by which this can be achieved?

A:

Recently discovered the following plugin has beta support for searching into linked source jars: https://github.com/ajermakovics/eclipse-instasearch
You have to enable searching source jars in the preferences as it is turned off by default. Depending on how much source you have, the indexing process is very slow, but then search is very fast. 
I have an Eclipse workspace with the enterprise versions of Alfresco (Explore, Share and SOLR) and Alfresco Workdesk (Vanilla, Office and Mobile). Indexing took about 8 minutes on my Early 2011 MacBook Pro. Search is almost instantanious.

A:

Searching inside a jar or finding the class name which contains a particular text is very easy with WinRar search. Its efficient and always worked for me atleast.
just open any jar in winrar, click on ".." until you reach the top folder from where you want to start the search(including subfolders).
Make sure to check the below options:
1.) Provide '*' in fields 'file names to find', 'Archive types'
2.) select check boxes 'find in subfolders', 'find in files', 'find in archives'.
