project-info.json missing "authenticated" flag sometimes if dependency has already been fetched into local maven repository

[trentonstrong]

My current workaround is to use the following one liner:

mvn -Dmaven.repo.local=mktemp -d -t maven org.nixos.mvn2nix:mvn2nix-maven-plugin:mvn2nix

[Profpatsch]

Can confirm, for local dependencies that are not available online.

Same here -- trying to build a project-info.json on a big project with no local repo is a bit painful.

The workaround given above does indeed work: mvn -Dmaven.repo.local=$(mktemp -d -t maven) org.nixos.mvn2nix:mvn2nix-maven-plugin:mvn2nix.

Could we change the title of this issue to something slightly more descriptive? e.g.

project-info.json missing "authenticated" flag sometimes if dependency has already been fetched into local maven repository.

Unfortunately the workaround does not work for me. I've even tried deleting the default local Maven repository but have had no luck. I'd appreciate any help if someone knows what the problem is.

---EDIT---

I tested the workaround on my system with Maven 3.2.5 in addition to Maven 3.3.9, but am still getting the attribute 'authenticated' missing error.

This is causing trouble for me too

[copumpkin]

I think this is just caused by this line being hidden behind if (res.getRepository() instanceof RemoteRepository), which I guess is not always the case.

[copumpkin]

The better solution though is probably just to amend the builder in nixpkgs to not assume it's there. Something like .authenticated or false would probably be all that it takes. I'll experiment and maybe push up a fix.

[joelthompson]

The workaround also doesn't work for exhibitor, as it has two modules in the top-level project, exhibitor-core and exhibitor-standalone, the latter of which depends on the former, and so it'll always be a local repo.

[datakurre]

@copumpkin Did you manage to experiment with fixing missing "authenticated" as you mentioned in June?

[ttuegel]

I followed up with @copumpkin's suggestion of .authenticated or false, but I found that a large number of dependencies on this project (kframework/k) also do not specify url or sha1.

[asymmetric]

@ttuegel Is it dependencies of dependencies that have no url and sha1?

e.g. maven-install-plugin > maven-project
