How to use relative-path-parameter with Spring Boot/picocli executable jar?

Question

I have a command line application, which uses Spring Boot and picocli. It is possible to pass parameter, which is a path, e.g. myApp.jar /path/to/file and it will do something with this file. I want to use this app system-wide, so I placed the executable .jar in /usr/bin/ and renamed it to myApp.

Now, when I use it with absolute path: myApp /home/user/file it works fine, but I want to pass relative path, e.g. when I am in /home/user/ I want it to be myApp ./file. The problem is that with relative path it tries to use /usr/bin/file instead of /home/user/file.

The workaround I use currently is something like this: myApp $(pwd)/file.

Do you have some idea how to fix this?

Ok, so I've managed to resolve the issue by using custom launch script for Spring Boot

I've copied original sources and removed lines responsible for working directory change:

run() {
  pushd "$(dirname "$jarfile")" > /dev/null # <-- removed
  "$javaexe" "${arguments[@]}"
  result=$?
  popd > /dev/null # <-- removed
  return "$result"
}

I am not very happy with this solution, but it is better than nothing.
