How to change "which java" path to the desired Java version

- open .bash_profile and add the following to make java version as needed ( I needed this for jenkins and maven project as mvn install was failing from the ci_workflow job

 export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.9.11-0.el7_9.x86_64

export PATH=$JAVA_HOME/bin:$PATH

- simply source the .bash_profile

[root@katello ~]# which java

/usr/lib/jvm/java-11-openjdk-11.0.9.11-0.el7_9.x86_64/bin/java

[root@katello ~]# java -version

openjdk version "11.0.9" 2020-10-20 LTS

OpenJDK Runtime Environment 18.9 (build 11.0.9+11-LTS)

OpenJDK 64-Bit Server VM 18.9 (build 11.0.9+11-LTS, mixed mode, sharing)

 Installing maven and setting JAVA_HOME on CentOS7.

download binary tar.gz from - https://maven.apache.org/download.cgi

move it to /usr/local/src/

- Run below command to untar the file

# tar -xvzf apache-maven-3.6.3-bin.tar.gz

- Rename the default directory 

# mv apache-maven-3.6.3/ apache-mvn/

- Go to /etc/profile.d

# vi maven.sh

#!/bin/bash

# Apache Maven Environment Variables

# MAVEN_HOME for Maven 1 - M2_HOME for Maven 2

export M2_HOME=/usr/local/src//apache-mvn/

export PATH=${M2_HOME}/bin:${PATH}

- change the permission to executable

# chmod +x maven.sh

# source maven.sh

[root@katello ~]# mvn -version

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

Ran into this error - I had two versions of JDK installed jdk1.8.0_271-i586 and java-11-openjdk-11.0.9.11-0.el7_9.x86_64 

- Simply followed the JAVA_HOME to set to the latest Java version

# .bashrc

# User specific aliases and functions

alias rm='rm -i'

alias cp='cp -i'

alias mv='mv -i'

# Source global definitions

if [ -f /etc/bashrc ]; then

        . /etc/bashrc

fi

#export JAVA_HOME=/usr/java/jdk1.8.0_271-i586

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.9.11-0.el7_9.x86_64

- This fixed the issue.
