Nixpkgs: collision between groovy LICENSE openjdk LICENSE

[pmahoney-raise]

Issue description

There is a conflict installing groovy and openjdk in the same nix profile. The LICENSE file exists at the toplevel; it should probably be located elsewhere for both packages.

Steps to reproduce

$ nix-env -iA nixpkgs.groovy nixpkgs.openjdk
...
collision between ‘/nix/store/mjd2gsnx14q6n05f8fwjk0ry6kms0m40-groovy-2.4.6/LICENSE’ and ‘/nix/store/g26vd7kl13vsfpghs9pks4avrwl8drng-openjdk-7u60b30/LICENSE’; use ‘nix-env --set-flag priority NUMBER PKGNAME’ to change the priority of one of the conflicting packages

Technical details

• System: OS X 10.10.5 Yosemite
• Nix version: (run nix-env --version) nix-env (Nix) 1.11.4
• Nixpkgs version: (run nix-instantiate --eval '<nixpkgs>' -A lib.nixpkgsVersion) 17.03pre94294.a057dfc

I think you could make a pull request, where you delete LICENSE in both package, within postInstall.

May be related to what I am seeing with bind in #19761

[sternenseemann]

Wouldn't it be more sensible to move it to, say, ${out}/share/<pkgname>/LICENSE in postInstall?

[vcunat]

Yes, this stuff should not be installed in top level.

[sternenseemann]

Okay, I will fix that. (Can someone assign me?)

[NeQuissimus]

I think only people with commit access can be assigned. But it's yours :)

@pSub: It looks like this can be closed, unless you want to cherry pick to 16.09
