Solution for “Not able to find Java executable or version” in Jenkins

This is the solution for the error I met in Jenkins when practicing the InClass exercise today. Hope it helps anyone who is also facing it.

After setting up everything as instruction for Jenkins -> Build Now -> I got an error (red progress bar) and when looking at Console output:

Not able to find Java executable or version. Please check your Java installation.
errorlevel=2

Note: My Java_Home, JRE_Home is still configured correctly in the environment variables.

Solution:

1. From Jenkins dashboard -> Manage Jenkins -> Global Tool Configuration

2. JDK installations -> Add JDK manually: JDK-1.8, JAVA_HOME= path to JDK folder (ex: C:\Program Files\Java\jdk1.8.0_202)

• Some people said we should also add:
• JAVA_HOME in Manage Jenkins -> Configure System -> Global properties: Add Environment variables.
• But I don’t do this step, it still works. If after step 2 above your Jenkins hasn’t worked yet, try this step.
