Maven Projects Cannot Find Java.

[dpkg-i-foo-deb]

When I create a Maven project and try to run it, it cannot be run because it doesn't find the java executable.
This is the generated output:

[ERROR] Command execution failed.
java.io.IOException: Cannot run program "java" (in directory "/home/dpkg/Workspace/Java/Estructuras_Datos/Red_Social/RedSocial"): error=2, No such file or directory
