There is a JVM argument
-Duser.dir
which can be used to set working directory for JVM.I found this SO post and it helped me solve my problem. Though I wanted to share something specific about IntelliJ that might trip somebody else up.
I have posted a picture below where the -Duser.dir flag is used and also the Working Directory text field is filled in.
In this situation, the Working Directory will be set to "JarLearning" rather than "2ndTry".
If it all possible I would rather use a script to run the java application and set the directory in the script:
The JNI-solution may affect all kinds of relative paths in your application; for examples the classpath you put in.
If you want to change the current directory, you'll have to use JNI and invoke a native API from your Java code. For example, for Windows you would use SetCurrentDirectory
