Update Grengine to 3.1.2 (group ID and package ch.grengine)

[alainstalder]

Hi, I'm the author of Grengine. I recently found out that Nextflow uses it, which I'm very glad to see!

As of version 3.1.0 (September 2024), Grengine moved back from ch.artecat.grengine to ch.grengine, both as the Maven group ID and as the Java package. Nextflow is still on ch.artecat.grengine:grengine:3.0.2. Sorry for the inconvenience of that move; had I known that Nextflow used Grengine, I would have thought twice about it.

This PR updates Nextflow to the new ch.grengine:grengine:3.1.2:

• modules/nextflow/build.gradle: ch.artecat.grengine:grengine:3.0.2 → ch.grengine:grengine:3.1.2. The exclude group: 'org.codehaus.groovy' is dropped because the published POM of Grengine 3.1.2 has no Groovy dependency.
• import ch.artecat.grengine.Grengine → import ch.grengine.Grengine in 7 files (5 main, 2 test).

Apart from the package name, the API of 3.1.2 is identical to 3.0.2's. The changes since then are all related to Grape and publishing, so they probably don't matter for Nextflow:

• Grengine's workaround for the Grape concurrency issue GROOVY-7407 now also works with Groovy 6 (3.1.1).
• The published POM no longer declares a runtime dependency on Groovy, which had slipped in with 3.1.0 (3.1.2).
• A workaround for GROOVY-12458, @Grab with the Maven Grape engine of Groovy 6 (3.1.2).

Grengine 3.1.2 is tested with Groovy 2.5 to 6 on Java 8 to 25.

For the old coordinates, I've published a relocation POM ch.artecat.grengine:grengine:3.1.1 → ch.grengine:grengine:3.1.1. Dependabot or Renovate may therefore propose that version, which would not compile because of the package change. This PR is the proper way to update.

Tested locally: the build succeeds and TaskRunTest and TaskDirectiveReadsTest, which use Grengine directly, pass.

If anything comes up, just ping me here.

Comment:

Updated to Grengine 3.1.2, released today: its published POM no longer declares a runtime dependency on Groovy (which had slipped in with 3.1.0), and it adds a workaround for GROOVY-12458. Title and description are updated accordingly.

(the branch name is grengine-3.1.1, but meant is now 3.1.2)

Hi! Thanks a lot, very appreciated

@pditommaso Sorry for the force push right after your approval: it only added the missing DCO sign-off to the last commit. CI workflows would need approval again it seems...

No pb!
