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.

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.

It is indeed.
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 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).

sorry i did not read your post correctly. especially that you are using

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

I suppose I could give it a try with java-9 on a VM. If that is what you require.

Installing java-9 on a VM shows there to be no jre supplied with java-9. So, I think
one must be content with running java-1.8 with maven.

2 things. First, you noticed that part of the message you got during the install
says....
The following packages have to be installed:
java-1.8.0-openjdk-devel-1:1.8.0.151-1.b12.fc27.x86_64 OpenJDK Development
Environment
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?

2 things. First, you noticed that part of the message you got during the install
says....
The following packages have to be installed:
java-1.8.0-openjdk-devel-1:1.8.0.151-1.b12.fc27.x86_64 OpenJDK Development
Environment
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.

2:42 p.m.
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..
3:16 p.m.
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.
