Package a prebuilt eclipse based app by nix

1

I knew the app is based on eclipse, so I have taken a look for built-eclipse in nixpkgs and code the wrapper. But now, it still has some problem.

The part nix expression of fixup is following.

        --prefix PATH : ${jdk}/bin
    )

I have no idea what I missed.

I solve this. Unpack the jar files and use ldd to find what I should to add into LD path. The reason is some dependencies of these depndencies are needed as well.

could you share the derivation please? I’ve tried grepping on nixpkgs, but I didn’t find anything. I’m trying to package an Eclipse-based binary as well, and I’m having a hard time with it.
