Thanks for your PR! Good work.

Missing settings.gradle causes composite builds to fail

I'm not really sure what you mean here. I cannot reproduce this. Can you please elaborate? Thanks.

GPG signing fails without a key property set

I also cannot reproduce this. Can you tell me, which Gradle command you executed and which error you got?

Missing settings.gradle causes composite builds to fail

To reproduce this you need to add the project, in my case as a git submodule, to another project and include it in your build as a composite build in the root projects settings.gradle like so:

includeBuild("gradle-download-task")

This results in an error about the build cache if I recall correctly and stems from not having a settings.gradle to isolate the project.

Gradle Composite Builds

We make use of composite builds extensively in our project and from experience, this is atypical to most project setups so I would not expect users attempting to contribute to this project would ever run into this issue.

GPG signing fails without a key property set

This has come up a few times such as Gradle 16597 which partially fixed the problem. Without a signing keyId you receive an error when trying to run publishToMavenLocal even though the the gradle documentation implies you should not. Gradle 5064 has the workaround I included in this PR to check if the keyId is set as part of the onlyIf evaluation.

Can you tell me, which Gradle command you executed and which error you got?

Yes, I apologize for the poorly described PR. I was actually trying to figure out why this plugin is hanging up my projects migration to Kotlin 2.0 (still have not figured that out) and ran into these issues in the process of that effort. I took the Gradle tasks from the workflow file to emulate your validation process.

./gradlew publishToMavenLocal test

I believe the issues encountered came from publishing and not testing which worked without issue for me.

OK. Got it. Thanks for the explanation.
