Passing arguments to eclipse through flatpak

Question

I run eclipse on linux mint. The installation uses flatpack as an envelope for execution. The exact command is: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=eclipse --file-forwarding org.eclipse.Java I want to pass the workspace path to eclipse and after googling, found that eclipse can take an argument specifying the workspace. Specifically, it is the -data argument, which takes a path to the workspace. So, I tried: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=eclipse -data <absolute path to workspace> --file-forwarding org.eclipse.Java However, flatpack returned an error stating it did not recognize -data. I then put the -data argument in both single quotes and double quotes, e.g., /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=eclipse "-data <absolute path to workspace>" --file-forwarding org.eclipse.Java Flatpack still returned the unrecognized error.

Can anyone advise me how to pass this argument to eclipse when it is executed through flatpack?

• greg-449: This seems to be flatpak not flatpack. Questions about a Linux command belong on Unix & Linux which has 150+ questions about flatpak
• nitind: Eclipse also already provides packaged downloadable tarballs that can usually update themselves. You need only unpack it into a location where your user has full permissions. No need to wait on, or trust in, whomever created that flatpak.
• rzwitserloot: The only sensible thing with the quotes would be /usr/bin/flatpak run --branch=stable --arch=x86_64 --command="eclipse -data <absolute path to workspace>".
• dnessett: @rzwitserloot: Quoting the whole command seemed to get around the unrecognized error, but now flatpak can't seem to find the eclipse executable. However, per the suggestion by greg-449, this is probable a flatpak question and I will move it to Unix & Linux.
