Using JAR resource as File in java or scala

Question

I have developed an application that basically searches its resources/runtime directory, looking for .java files.

Having fetched all .java sources, it (together with program arguments) passes their absolute paths to JavaCompiler .

Of course, this approach doesn't work when application is deployed as a JAR package. So the question - how can I work with resource files as with regular files, ie pass their absolute path and read them afterwards?

I found some related topics here:

• reading the file as a stream
• making a resource copy to some temporary file

But what if I don't know names of the files? I seek solution that allows me to search the resources/runtime directory. Moreover, I think making a copy of file somewhere and delete it later on is clumsy solution.

I use combination of Java and Scala (with sbt build system), hence solution Java or Scala would be great.

Refer to this and see if it answers your question.

Edit: How do I list the files inside a JAR file?
