Question

I have a maven project, in which, I am trying to execute a script (written in R). I put this script file in the source code directory as well. I found this script is not executed at all. However, when I move this script outside the jar file, it does execute ! Can anyone tell me why, and give me some solutions to put the script inside the jar while ensure its execution?

Thanks a lot !

Answer 1

I would do the following:

• Get InputStream for the file with ClassLoader.getResourceAsStream()
• Write this InputStream to tmp dir
• Execute it with Runtime.getRuntime().execute(..)
