https://bugzilla.redhat.com/show_bug.cgi?id=1810950 Bug ID: 1810950 Summary: Maven package requires JDK 8 specifically and ignores alternatives Product: Fedora Version: rawhide Hardware: All OS: Linux Status: NEW Component: maven Severity: medium Assignee: stewardship-sig(a)lists.fedoraproject.org Reporter: tristandeloche(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: decathorpe(a)gmail.com, java-sig-commits(a)lists.fedoraproject.org, mhroncok(a)redhat.com, mizdebsk(a)redhat.com, msrb(a)redhat.com, sochotni(a)redhat.com, stewardship-sig(a)lists.fedoraproject.org Target Milestone: --- Classification: Fedora Description of problem: Version-Release number of selected component (if applicable): at least since Fedora 31 How reproducible: always reproducible Steps to Reproduce: 1. Install any JDK package that's not 8 (and its "-devel" version) 2. Install maven package (which requires JDK 8) 3. Set the "java" and "javac" alternatives to that other JDK 4. Check "mvn -v", see that it still uses JDK 8 forcefully Actual results: Maven is executed with JDK 8 Expected results: Maven is executed with the JDK set using alternatives (reasonably the one of "javac", but maybe should be another alternative alias as its a jdk reference rather than one to the javac binary) Additional info: Assuming no JAVA_HOME, no .mavenrc etc, the /usr/bin/mvn script has the following line: if [ -f /usr/share/java-utils/java-functions ] ; then . /usr/share/java-utils/java-functions set_jvm set_javacmd fi And in /usr/share/java-utils/java-functions we have, amongst others: ... case "${_prefer_jre}" in 1|[Yy][Ee][Ss]|[Tt][Rr][Uu][Ee]) dirs="/usr/lib/jvm/jre-1.8.0-openjdk:/usr/lib/jvm/java-1.8.0-openjdk" ;; *) dirs="/usr/lib/jvm/java-1.8.0-openjdk:/usr/lib/jvm/jre-1.8.0-openjdk" ;; esac ... Meaning that assuming no override, we will always use the JDK 8 installed as a dependency of maven, ignoring any user system-wide Java alternative setting. -- You are receiving this mail because: You are on the CC list for the bug.
