Eclipse - How to find out which libraries your project actually uses

Question

Hello all,

I installed ZK Studio plugin for eclipse and have used it to create a new ZK based webapp. However, inside my /WebContent/WEB-INF/lib folder, there are a number of .jar files that were included automatically (beloning to the zk framework). I'm assuming this was done by selecting "create a new ZK project". However, when it comes time to deploy this to the webserver, I only want to include the libraries I actually need and use. Is there a way of finding that information out so I can shrink the size of my .WAR file?

Thanks!

Answer 1

These are called "transitive dependencies" - libraries that required by libraries that you use. The libraries that you use can't work without their dependencies, so ultimately you need all of the jars in WEB-INF/lib.

Maven is a dependency-management tool that tells you what are the transitive dependencies, (via a dependency graph). I would recommend using maven, although it would require some effort to introduce it in the current project.

Answer 2

Take a look at The Content of ZK Binary Distribution then you can remove the library you don't need :)
