It is visible in current GHA runs that building jtreg in all worker at once sometimes break on dependencies checkout, for example:
[build.sh][INFO] CYGWIN_OR_MSYS=0 [build.sh][INFO] JAVA_HOME: /usr/lib/jvm/temurin-17-jdk-amd64 [build.sh][INFO] Downloading https://archive.apache.org/dist/ant/binaries/apache-ant-1.10.8-bin.zip to /home/runner/work/jdk/jdk/jtreg/src/make/../build/deps/apache-ant-1.10.8-bin.zip Error: sh][ERROR] wget exited with exit code 4 Error: Process completed with exit code 1. I suppose this is a side-effect of pulling lots of dependencies all at once. Building jtreg on every platform exposes us to these issues more often. Additionally, we had problems with building jtreg on various platforms. We do not have to build jtreg for every platform. We can just have a job step that does it once, and stores it in the cache for all dependent jobs to use. It would also save some build time across various jobs. ------------- Commit messages: - Fix - Rename select -> prepare - Fix Changes: https://git.openjdk.org/jdk/pull/21692/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21692&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8342988 Stats: 65 lines in 6 files changed: 28 ins; 7 del; 30 mod Patch: https://git.openjdk.org/jdk/pull/21692.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21692/head:pull/21692 PR: https://git.openjdk.org/jdk/pull/21692
