Hello fellow java package maintainers! We are planning to bump the JDK from java-1.8.0-openjdk to java-11-openjdk for F33. Please see https://fedoraproject.org/wiki/Changes/Java11 Short Story: * if you have some java package, be aware that we are bumping JDK in rawhide * Ensure your package builds and runs fine with JDK11 (see the https://copr.fedorainfracloud.org/coprs/jvanek/java11/builds/) * there is special tooling ready for this, before mass rebuild is launched ** See https://fedoraproject.org/wiki/Changes/Java11#copr_preliminary_rebuild * If you do not want Fedora rotten with JDK8 for ever, continue reading Long Story: We ran a preliminary mass rebuild of javastack in copr repo https://copr.fedorainfracloud.org/coprs/jvanek/java11/builds/ (select "all" instead of "25" at the bottom), on packages requiring java,javac, java-devel, maven-local, ant, ivy & comp for build. You can see, the result was quite dramatic: 1225 total; attempted to rebuild 483 failed; from those 191 are trivial failures (but if you fix it, there is no guarantee real troubles are not hidden behind that) 186 succeeded 556 orphans or dead or otherwise tragic so the build did not even start I would kindly ask you to search yourself in this list: https://jvanek.fedorapeople.org/java11/people If you are here, please check status of your package in https://jvanek.fedorapeople.org/java11/init (pain text of https://copr.fedorainfracloud.org/coprs/jvanek/java11/builds). * If your package is "succeeded", congratulations nothing to do, and just keep en eye on JDK bump * If there is "failed" but contains "- -" then it is probably orphan. If you wish to resurrect it, please ensure it runs against JDK11 (see lower) * If there is "failed" but failed in "seconds", then those packages failed so quickly, that the build was in initial phases. That usually mean that you build with source/target lower then 1.6 JDK11 supports 1.6 and up. We recommend to bump the source/target to 1.8, to allow existence of compact 1.8 packages alongside main javastack. See https://fedoraproject.org/wiki/Changes/Java11#Wrong_source.2Ftarget_version. Don't forget to upstream the patch, or maybe it is enough to update to more fresh upstream release which supports JDK11? it may happen, that after the fix, your build will fail in more terrible way (see below) * If there is "failed", and its none of above, then your package simply failed. Very often the scary error may be fixed by bump to latest upstream version. JDK 11 is out for several years. Please, try to fix the package. Don't hesitate to ask on devel@xxxxxxxxxxxxxxxxx or java-devel@xxxxxxxxxxxxxxxxx or directly to me jvanek@xxxxxxxxxx. If you fix the fail, feel free to share your fix, it may help others. We are trying to gather the most common issues at https://fedoraproject.org/wiki/Changes/Java11#common_issues_packagers_can_face_and_gathered_solutions . Feel free to enhance the page, or write us your case (possibly both with solution and without) so we can add it here. Debugging Your failures. The copr repo we maintain, contains builds of java-11-openjdk as system JDK, javapackages-tools honoring that, and java-1.8.0-openjdk as non system JDK. Also it contains successfully rebuilt packages. You can directly use this copr repo in several ways. * first glance on error. On https://copr.fedorainfracloud.org/coprs/jvanek/java11/builds/ find your build (select "all" instead of "25" at the bottom), ** Click its number, select chroot (currently fedora-32-x86_64 ) and check the logs. Main log is build.log.gz. * anything you push to rawhide, will automatically rebuild here in f32 chroot (we have a JDK in rawhide broken a bit currently) ** It is the best approach. If you can fix your package in rawhide directly, without breaking the rawhide too much, go for it ** If yo need to experiment, I have a mock config for you (generated from copr-cli mock-config jvanek/java11 fedora-32-x86_64) which you can copy to your /etc/mock and use - https://jvanek.fedorapeople.org/java11/jvanek-java11-fedora-32-x86_64.cfg . Eg: sudo cp downloaded-fedora-32-x86_64.cfg /etc/mock/jvanek-java11-fedora-32-x86_64.cfg # change spec, bump sources, apply patches fedpkg srpm mock -r jvanek-java11-fedora-32-x86_64 *.src.rpm Or any other packaging workflow you use, and you can use against the copr repo. Thank you very much for your help, there are 500 failures, and 1000 java packagers, but only 2 active members of java sig. Without your help, the JDK bump will be very hard. Thank You!
