Maven cannot find compiler on Linux

Problem:

I installed the new Fedora, Maven, and Eclipse system. I checked the project and now I am trying to download all the dependencies manually using the terminal.
Execution mvn clean installI get:

which: no javac in (/home/user/apache-maven-3.2.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/user/.local/bin:/home/user/bin)
Warning: JAVA_HOME environment variable is not set.

// ... successfully downloading all dependencies ...

Additional Information:

I have not installed Java yet, I am using what is already supplied with Fedora.
The /usr/lib/following folders are located:

  • Java
  • Java 1.5.0
  • Java 1.6.0
  • Java 1.7.0
  • Java 1.8.0
  • Jvm

Except jvm, all other folders look empty.

jvm contains the following folders:

  • Java-1.7.0-OpenJDK-1.7.0.60-2.4.3.0.fc20.x86_64
  • jre-1.7.0-openjdk-1.7.0.60-2.4.3.0.fc20.x86_64 (link to java-1.7.0-openjdk-1.7.0.60-2.4.3.0.fc20.x86_64/jre)
  • jre-1.7.0-openjdk (link to /etc/alternatives/jre_1.7.0_openjdk)
  • jre-1.7.0 (link to /etc/alternatives/jre_1.7.0)
  • jre-openjdk ( /etc/alternatives/jre_openjdk)
  • jre ( /etc/alternatives/jre)

Eclipse- > - > Java- > JRE /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.3.0.fc20.x86_64

$ vi ~/.bash_profile export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.3.0.fc20.x86_64.
