Re: Maven won't pick up JAVA_HOME
Case closed. Turns out I had improper JAVA_HOME defined in ~/.mavenrc which overrides user env and that is why it worked as root. I had to debug the mvn bash script to get to the core of it. Too bad maven fails with not much info in case like this. If you run with -X it could at least tell you the current config and where it is taking the vars. :sadface: Thanks everyone for given help. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
Re: Maven won't pick up JAVA_HOME
Small update: I nuked all presence of java and maven with dnf autoremove and then reinstalled maven and it did indeed install all the necessary packages and now I also see the jre folder in the /usr/lib/jvm/... but still! the same error. What is more interesting though is that if I switch to root user, maven suddenly works. So it must be something going on with my user shell.

FWIW, I restored the snapshot of my VM so that no java packages or maven was installed. I then did a "dnf install maven" and these are the packages it installed.

I noticed the same thing today while reconciling a few config files with
their ".rpmnew" versions for packages updated via dnf. I can't recall
which package it was though but I saw that "/usr/lib/jvm/jre" does't
exist ("/usr/lib/jvm/java" does).

Maven won't pick up JAVA_HOME
Perhaps I am just going crazy but maven just won't pick up JAVA_HOME on F27. 1. sudo dnf install maven 2. echo $JAVA_HOME returns /usr/lib/jvm/java-9-openjdk-9.0.0.181-7.fc27.x86_64 (which includes bin dir with JDK tools such as javac, keytool etc so it is JDK for sure) 3.
