Also, you don't need to change it later when updating Java. share|improve this answer edited Jul 18 '15 at 23:46 answered Feb 24 '15 at 1:48 rbento 2,58612333 What if I want to make this persistent between launches? –Igor Ganapolsky Apr 6 at 13:09 add a comment| up vote 7 down vote JAVA_HOME should be /usr/lib/jvm/java-7-oracle/jre/. share|improve this answer answered Dec 5 '14 at 15:42 talex 3,941732 Right, you need to remove the trailing "/bin/java" from your path .. meaning: JAVA_HOME="/usr/lib/jvm/java-7-oracle/jre/" –dariusz May 25 '15 at 15:09 add a comment| up vote 4 down vot

When I type java -version I am getting: java version "1.7.0" Java(TM) SE Runtime Environment is not defined (build 1.7.0-b147) This is correct. And I tried to install maven, and added to etc/environment file: JAVA_HOME=/usr/lib/jvm/jdk1.7.0 M2_HOME=/usr/local/apache-maven/apache-maven-3.0.4 MAVEN_HOME=/usr/local/apache-maven/apache-maven-3.0.4 M2=/usr/local/apache-maven/apache-maven-3.0.4/bin Now When I type mvn I am getting: Error: JAVA_HOME is not defined correctly. We cannot execute ”/usr/lib/jvm/jdk1.7.0”/bin/java However I am not putting " mark for JAV_HOME var in environment file. It is trying to run from ”/usr/lib/jvm/jdk1.7.0”/bin/java path, Actually it should be /usr/lib/jvm/jdk1.7.0/bin/java When I command $JAVA_HOME I am getting: bash: ”/usr/lib/jvm/jdk1.7.0”: No such file or directory I am sure the path(/usr/lib/jvm/jdk1.7.0) is correct.
