No JAVA_HOME variable detected even if defined.

[Karim Ennassiri]

I'm trying to change the default database connector in Jira software. It is already installed, so I found that I can change the DB connector via the config. sh script. When I try to lunch the script, I have a Jira error which tolds me that there is no JAVA HOME variable is defined. 

No JRE_HOME or JAVA_HOME environment variable is set - attempting to just run java command
Wrong JVM version! You are running with java version "11" 2018-09-25.. but JIRA requires at least 1.8 to run

 Instead the variable is well defined : 

echo $JAVA_HOME
/opt/jdk/jdk-11

 And i think that Jira is not happy with the last version of Java too. 

Thank you for your help.

Hello,

Jira does not work with Java 11. You should either intall Java 8 or use the inbuild jre into Jira. Set the JAVA_HOME to the correct JVM
