Using a version older than Java 16 with the original BuildTools causes the build to fail as Minecraft 1.17 requires Java 16 and Tool preparations are done without telling the tool a version to build (until now).
Additionally the test builds in this repo have been updated to use java 16 for the latest build.
Running it twice shows how fast the Action can be, when skipping versions that already exist inside the local maven repository.
