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

As previously noted.  I got....

[egreshko@acer ~]$ mvn -v
Apache Maven 3.5.0 (Red Hat 3.5.0-6)
Maven home: /usr/share/maven
Java version: 1.8.0_151, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-1.b12.fc27.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.13.15-300.fc27.x86_64", arch: "amd64", family: "unix"

on my default testing system.

Note that the Java home points to a "jre" directory.

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.

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:

Install package 'maven' to provide command 'mvn'? [N/y] y

/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


Something on my system seems to be off and I have no idea what.
