Hi Guys, I have configured Maven in Jenkins. But it is showing me the below error when I tried to run any job.

[maven] $ /maven/bin/mvn -f pom.xml clean package
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
Build step 'Invoke top-level Maven targets' marked build as failure
Finished: FAILURE

How can I solve this error?

You may get java_home should point to a jdk not a jre error if you didn't set your java path in .bashrc file. First try to check the Maven version using the below given command.

[root@localhost ~]# mvn -version

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

Maven home: /maven

Java version: 1.8.0_221, vendor: Oracle Corporation, runtime: /usr/java/jdk1.8.0_221-amd64/jre

Default locale: en_US, platform encoding: UTF-8

OS name: "linux", version: "4.18.0-80.el8.x86_64", arch: "amd64", family: "unix"

You can see java home in your output. Copy the path till /usr/java/jdk1.8.0_221-amd64 and set this path in .bashrc file.

JAVA_HOME=/usr/java/jdk1.8.0_221-amd64
