Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
Root Cause
The issue is happening because of incorrect logic in the script setjre.sh :
if [ -z "$JAVA_HOME" -a -z "$JRE_HOME" ]; then echo "Neither the JAVA_HOME nor the JRE_HOME environment variable is defined" echo "At least one of these environment variable is needed to run this program" exit 1 fi fi if [ -z "$JAVA_HOME" -a "$1" = "debug" ]; then echo "JAVA_HOME should point to a JDK in order to run in debug mode." exit 1 fi if [ -z "$JRE_HOME" ]; then JRE_HOME="$JAVA_HOME" fi echo "Setting JRE_HOME...." JRE_HOME="/opt/atlassian/confluence/jre/"; export JRE_HOME
When the execution will got into the condition {{ if [ -z "$JAVA_HOME" -a -z "$JRE_HOME" ]}} it terminates with exit 1; so JRE_HOME="/opt/atlassian/confluence/jre/"; export JRE_HOME will never be executed.
There's a bug in the shell script. If there's a /usr/bin/java file, then JRE_HOME will be temporarily set to /usr and then it will be corrected at the end of the script. So this issue happens on a Linux machine that doesn't have the default JVM installed.
Workaround(s)
- Set JAVA_HOME="/opt/atlassian/confluence/jre/" explicitly before starting Confluence (keep in mind that /opt/atlassian/confluence/jre is the path to Confluence installation direcotry and should be adapted if you are using your own path)
- Use Confluence with external Oracle JDK (recommended)
- Remove the exit 1 lines
- Move JRE_HOME="/opt/atlassian/confluence/jre/"; export JRE_HOME to the top of setjre.sh
