add support for compiler participants ?

[foreveremain]

Thanks so much for creating this new ecj plugin ! Do you think there's a possibility to allow execution of ecj compiler participants ? These are normally bundled as regular eclipse plugins, and the one I'm familiar with is https://github.com/java2script/java2script/ - which transpiles Java code to .js files, allowing Java swing apps to run in the browser (I develop this one: https://www.jalview.org/jalview-js/JalviewJS.shtml but the plugin's main developer is @BobHanson, who also develops https://chemapps.stolaf.edu/jmol/jsmol/jsmol.htm ).

Hi! I've taken a brief look at Eclipse JDT's compilation participants but I'm not sure what is required to set them up. This plugin is invoking ECJ via its command line interface and all I can find are docs about how to set it up programmatically. This is something I am not willing to change since a programmatic solution would require using a lot of unstable Gradle internals.

Also note that if it's possible to add participants via CLI, you should already be able to do that by modifying the freeCompilerArgs of the JavaCompile task. It is possible that I'm misunderstanding something, so if you have more information, please let me know.

Due to the lack of follow-up and the reasons stated above, this will not be worked on for now. I might revisit this at some point if Gradle opens up the API for custom Java compilers.

Nice to see some activity here. The news that gradle 8 might not support ecj meant I didn't pursue this further - and somehow I missed your july 21 comment about freeCompilerArgs. We're still working with the java2script compiler participant - perhaps I'll find some time to experiment.
