JAVA_HOME path not pointing to correct path

Question

I am using a VPN environment for code. Everything was working fine, but now I am not able to execute maven commands.

The error that I get is :

NB: JAVA_HOME should point to a JDK not a JRE

Now when I run the following : %JAVA_HOME% I get the following : C:\Program Files\apache-maven-3.6.3\bin instead of C:\Program Files\Java\jdk1.8.0_251

And running : java -XshowSettings:properties version

The Java_Home path seems to be an admin settings which I cannot change myself. So, is there anything which I can do for this problem from my side?

Answer 1

Changed the

Environment Variables

Hope the problem will be solved

New System Variable

In my cases, it looks like

Answer 2

You can override the JAVA_HOME variable setting it in the Maven script file.

To do so, edit mvn.cmd and add the following line in the beginning of the file:

set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_251"

Answer 3

Add jdk physical path to environmental variable. It should resolve the problem
