Re: [tycho-dev] Tycho 3.0 release

I really think we should only update to java 17 if there are dependencies in Tycho requiring it.

Requiring build systems to update their java version often brings some rumor and I currently do not see we can take advantage of any Java 17 feature in tycho that would justify that given that people can always run Tycho with Java 17, 18, ... whatever they like already.

    I would add say the following should considered breaking:

    - changing the java version to run the build
    - requiring a new minimum maven version (e.g. once we require maven 4)
    - requiring to change their pom.xml in a non trivial way (e.g. beside
    changing some configuration value in an existing mojo)

I agree with this view. And I would like to see Tycho 3.0 requiring Java 17 at runtime . So I repeat my proposal - work on 3.0 branch for any such change now if needed although some of the deletions (e.g. pack200) can happen easily once 3.0 branch is merged in master. Which should happen after Tycho 2.x release based 2022-03, I can't say right now what fixes (if any!) will land in p2/ecj but I expect at least some PGP related changes and Probably Java-18 target support (but not producing Java 18 bytecode) being added by that time. These could happen to be critical for projects willing to go more the PGP way and/or just being able to build running Java 18 thus I consider them important for regular releases.

    I think everything listed under milestone 3.0 is a breaking change,
    maybe the fixSWT could be considered as non breaking) one.
