I installed java jdk hotspot 1.7. When I type java -version I am getting:

java version "1.7.0"
Java(TM) SE Runtime Environment (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.

JAVA_HOME should be set to the name of the directory that contains the bin directory that contains the Java executables (in particular, java itself).

Assuming you do have a /usr/lib/jvm/jdk1.7.0 directory, it probably contains a jre subdirectory that contains the bin directory that contains java and related executables.

So you should probably be setting JAVA_HOME to /usr/lib/jvm/jdk1.7.0/jre rather than /usr/lib/jvm/jdk1.7.0.
