Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/leiningen) and found it was in an excellent condition.

@conda-forge/help-java Hello, ready for review

We need the statically bundled third-party licenses for this. There is at least a maven plugin that can produce these lists, but I'm unsure whether it will work here.

This recipe simply installs the standalone JAR. There are licenses in an XML format in most of the packages in the archive, but I think that one does not have a license.

My understanding is that I should build the JAR from source and collect the licenses from the pom.xml. I did try a few times to build from source but failed, then gave up and went the JAR repackaging - Do you think that I am missing/misunderstanding something?

I will come back to this later - currently, I am struggling with zig and getting close to a sbcl linux recipe

@xhochy This recipe now has the third-party licenses. Since this is a java package, is the noarch: generic correct?
I get the licenses from the source directory pom.xml file, then build the uberjar and install that over the upstream one

Thank you for doing this so throroughly!
