I assume the build is using Java 11 because all of the plugins have sourceCompatibility, targetCompatibility as Java 11. @stuartmorgan-g is that correct?

[stuartmorgan-g]

build_all_packages_legacy is run on a machine that installs Java 11 because we needed it still; see here and here. You'd need to bump that in the PR.
