Support for Jib extensions

[ryandens]

I know this is explicitly called out in your README, so feel free to close if not, but do you have any interest in having this project support the Jib extension API?

This is a powerful mechanism to allow users to opt into more specialized optimizations for their projects. I maintain two such extensions/plugins

• https://github.com/ryandens/javaagent-gradle-plugin/
• https://github.com/ryandens/jlink-gradle-plugin/

This plugin can support this API using the same techniques as the upstream Jib project. The only tweak that would be needed is to not support the usage of the GradleData parameter offered by this extension point, as usage of Project APIs at task execution time makes a task incompatible with the configuration cache

I was able to prototype this and validate this can work in a configuration cache compatible manner with the extensions I'm aware of. If you're open to accepting external contributions, I'd be happy to tidy it up and contribute it.

Thanks for making a great project!

I'm generally open to the contribution. Test coverage of that functionality would be a must, because none of my projects have any use for this. Would you be willing to work on issues related to the functionality going forward? Not that I expect much.

Excellent, thanks!

💯 My tenative plan is to add tests leveraging some of google's first party extensions and/or my third party extensions.

Defintiely! I've maintained my plugins/extensions in this area for several years at this point, and would be happy to assist with maintenance and future improvements in this area.

I'll update this issue as I make progress towards this enhancement

Great, feel free to create a draft pr early, if you think that's valuable.
