Though I have Java enabled in the server, I'm facing java path issue

[vijay cvs]

I'm generating war file using Gradle using shell script but  I'm getting the below error.

ls
cd ClaimCenter1003
javac -version
chmod 777 gwb.sh
./gwb.sh warTomcatDbcp

05-Jun-2020 13:22:54	ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

05-Jun-2020 13:22:54	Please set the JAVA_HOME variable in your environment to match the
05-Jun-2020 13:22:54	location of your Java installation.

Java is set in all the bamboo servers though not working in many server through the console but when I triggered the build from command Line it is working fine. 

The build is working in some servers giving me the output as I needed: 

javac 1.8.0_161
build	05-Jun-2020 13:18:01	Downloading file:/opt/bamboo-agent-home/xml-data/build-dir/GUID-GCCA-VAR/ClaimCenter1003/gradle/wrapper/./gradle.zip

build	05-Jun-2020 13:18:04	 - Control which dependencies can be retrieved from which repositories
build	05-Jun-2020 13:18:04	 - Production-ready configuration avoidance APIs

Build going through when did in CLI

Please help me through this. Thank you

Find out what user Bamboo is running, if so then try logging in with that user and typing the command "java -version". If you can't, then you have to log in as Root to give access to the Bamboo user.
