Upgrade to gradle 8

[maths22]

This allows local development to work with java 17.

I have tested that publishing to maven local works correctly
with javas 8, 11, and 17. I have not tested publishing to
maven central/staging as I do not have access to do so. I
have tested publishing to a different repository with a
custom repository block, and that appeared to work correctly,
but I wouldn't be surprised if this needs tweaks to be happy
for maven central.

Hi @maths22,
We'll know when the next version of JavaPackager is released 😅
Thanks so much!!

[fvarrui]

Now it seems to be a little better organized, because Gradle is not my thing.

Merged in branch pr-310

Thanks so much!!! It worked like a charm. I was able to release JP 1.7.1. to Maven Central with minor changes. Merged into devel.

Hi @maths22! Maybe you can throw some light, because I'm having a problem when releasing the plugin to Maven Central. My minor changes in build.gradle broken the Gradle compatibility (but fixes the next problem), so I revert those minor changes. Now, the problem is that the publish task uploads JP jar, source jar, docs and some other necessary files, but it also uploads a folder called plugin, which is detected as a bad thing when releasing .... so, I have to access to OSS Sonatype web interface, delete this folder, and finally close and release the repo manually. Do you know how we can avoid to upload this folder?

[maths22]

Hmm I'll look into this.

@fvarrui if you are able to provide a screenshot or log of the error message I think that would be helpful. Since I can't try publishing to the repo I can't directly reproduce it myself, and it doesn't seem to publish a plugin directory when i push to mavenlocal

[fvarrui]

As you can see here, it generates a plugin directory into my local repo (maybe needed if the plugin is released to Gradle plugin portal) ... but it's detected as a wrong artifact when releasing to Maven Central.

But when releasing to Maven Central:

> Task :closeRepository
DEPRECATION WARNING. The staging repository ID is not provided. The fallback mode may impact release reliability and is deprecated. Please consult the project FAQ how it can be fixed.
Requested operation was executed successfully in attempt 13 (maximum allowed 21)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':closeRepository'.
> Wrong 'iogithubfvarrui-1060' repository state 'open' after transition (expected [closed]). Possible staging rules violation. Check repository status using Nexus UI.

* Try:

And this is the error message in Nexus Repository Manager:

And when I delete this folder (1) and manually close the repo (2), the plugin is released successfully:

I filed #327 to hopefully deal with this. Thanks for the additional info-that was helpful in tracking down the POM and figuring out which part of the gradle docs to look at.
