Adding the `-only` suffix does indeed disable dependencies, so you have to manually set up your build directory state to have all the dependencies built already. This would be a reasonable sequence for getting relevant timings. First make sure all dependencies have been built: $ make java.desktop-libs Then delete only the things you want to rebuild and run the part of the build that is relevant. This can be repeated. $ rm -rf build/<your-build-dir>/support/modules_libs/java.desktop $ time make java.desktop-libs-only JOBS=1 ------------- PR Comment: https://git.openjdk.org/jdk/pull/23332#issuecomment-2636960207
