[FIXED] Bamboo fails with JAVA_HOME should point to a JDK not a JRE in Maven task on CentOS 7

Issue

I am running Bamboo on CentOS 7. My JAVA_HOME/bin/java and java commands refer to the same thing, and they are set properly:

~$ echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre
~$ 

I am also setting my JAVA_HOME variable in .bash_profile. I have put it in <bamboo installation dir>/bin/setenv.sh too. However, in my Maven tasks in Bamboo fail with:

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

I don't know how to debug this and how can I provide any further information. When I ssh into the server that Bamboo is installed, I can run mvn commands without any issues.

Solution

So, it is not about how you set the JAVA_HOME variable for Bamboo, but it's about how Bamboo sets its JAVA_HOME variable for it's java executable. It is in the database. It was the value before I made an update to java and deleted the old version and I have changed it from Bamboo administration > JDKs to /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre and done, the issue is resolved.
