Java build systems (Ant, Maven, Gradle) used to require "java-devel" because their typical usages involves code compilation, which requires full JDK. In Fedora 23 I've just replaced hard requirement on "java-devel" with recommends. From now on Ant, Maven and Gradle require "java-headlesss" and recommend "java-devel", which means that by default they will still be installed with full JDK, but it will be possible to install and use them with just headless JRE. -- Mikolaj Izdebski Software Engineer, Red Hat IRC: mizdebsk -- java-devel mailing list java-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/java-devel
