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. Any mvn command results in
The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE
Also tried JDK8 and Oracel Java 9
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-1.b12.fc27.x86_64
export JAVA_HOME=/usr/java/jdk-9.0.1
..same result. I feel like there is some hidden config messing me up
or some weird stuff happening. Anyone has an idea what it could be? Last time I was still on F26 and it worked.

then it should usually works out of the box. As Ed wrote, $JAVA_HOME should point to the JRE. But in my case, there is no $JAVA_HOME defined, maven uses the defaults from /etc/alternatives. So you can try to unset JAVA_HOME.

I have a "default" F27 KDE system on a testing laptop. I don't know if you have a requirement to use java-9. But in the "default" system java 1.8 is installed.
I just installed maven and it added

That can't be true because I used maven with java 9 in F26 from updates-testing with absolutely no problems. And I have same problem with java 8 anyway.
After removing all versions of java and maven with dnf I tried to do a fresh install and now even that fails:

2 things. First, you noticed that part of the message you got during the install says....

Which is telling you that maven is depending on java-1.8.
Second, a question. When you ran the command did you have JAVA_HOME set? If you did, how about trying it again without it being set?

Yes, apparently I did have JAVA_HOME set. After unsetting the variable and reinstalling maven again it completed successfully. However, problem persists:
mvn -version /usr/bin/mvn: Failed to set JAVACMD The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE
One other thing I found after install is this: pwd /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-1.b12.fc27.x86_64/bin ./java -version Error: could not find libjava.so Error: Could not find Java SE Runtime Environment.
So this java 8 install as a weak maven dependency seems to be borked.

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.

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. Investigating further..
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.

- Any mvn command results in
The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE
Also tried JDK8 and Oracel Java 9

export JAVA_HOME=/usr/java/jdk-9.0.1
..same result. I feel like there is some hidden config messing me up
or some weird stuff happening. Anyone has an idea what it could be? Last time I was still on F26 and it worked.
The last time I did anything with java the JAVA_HOME variable needed to be pointing to the jre (java runtime engine) directory.
Also, you should be using /usr/lib/jvm/java since your path will become invalid on upgrades.
Hm, there is no jre directory.

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).
