How to get Maven 3.0.4 to use Java7?

Question

I've just updated maven from 3.0.3 to 3.0.4 using the compiled binaries from the official site.Now when I run mvn -version , it says that it uses the old java 6 version , instead of the java 7 version that I have installed on my machine (macbook pro). If I run the 3.0.3 version maven binary from inside its folder it uses the java 7 version. How can I configure maven 3.0.4 so that it uses the Java 7 version? Thank you.

PS : Java 7 is the default java version at my system (mountain lion).

Answer 1

Set the JAVA_HOME environment variable. and path as $JAVA_HOME/bin

From Apache maven:

Unix-based Operating Systems (Linux, Solaris and Mac OS X)

Extract the distribution archive, i.e. apache-maven-3.0.4-bin.tar.gz to the directory you wish to install Maven 3.0.4. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.0.4 will be created from the archive. In a command terminal,

add the M2_HOME environment variable, e.g. export M2_HOME=/usr/local/apache-maven/apache-maven-3.0.4.

Add the M2 environment variable, e.g. export M2=$M2_HOME/bin.

Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

Add M2 environment variable to your path, e.g. export PATH=$M2:$PATH.

Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.* and that $JAVA_HOME/bin is in your PATH environment variable.

Run mvn --version to verify that it is correctly installed.
