[maven] How to change maven java home

Great helps above, but if you having the similar environment like I did, this is how I get it to work.

  • having a few jdk running, openjdk, oracle jdk and a few versions.
  • install apache-maven via yum, package is apache-maven-3.2.1-1.el6.noarch

Edit this file /etc/profile.d/apache-maven.sh, such as the following, note that it will affect the whole system.

$ cat /etc/profile.d/apache-maven.sh
MAVEN_HOME=/usr/share/apache-maven
M2_HOME=$MAVEN_HOME
PATH=$MAVEN_HOME/bin:$PATH
# change below to the jdk you want mvn to reference.
JAVA_HOME=/usr/java/jdk1.7.0_40/
export MAVEN_HOME
export M2_HOME
export PATH
export JAVA_HOME
