Jenkins wont start-CodePudding

I am attempting to start and getting the following error

root@ip-172-31-80-112 ~]# systemctl start jenkins

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details

I have java installed as can be seen from the java version below

[root@ip-172-31-80-112 ~]# java -version

below is my bash profile showing my JAVA_HOME variable

can anyone help me with this issue. Thank you in advance. It looks to be some issue with Jenkins not being able to find my java version on my server, possibly some link pointing to the wrong location

I am getting the same error.

Journalctl log: invalid Java version: openjdk version "1.8.0_342"

java -version openjdk version "1.8.0_342" OpenJDK Runtime Environment (build 1.8.0_342-b07) OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode)

CodePudding user response：

It seems like you have multiple java versions available on your machine. Can you update correct version by simply running sudo update-alternatives --config java to avoid jenkins and java version mismatch?
