I’m not a Java developer and don’t have to compile much Java. Unfortunately sometimes I do, and on those rare occasions it usually goes wrong.
Today my problem was with Maven 3. I installed using apt-get install maven 3, however when I tried to use the mvn command I got the error “program mvn not found”. This is a because the command is mvn3! So there are two options.
1) Use mvn3 install
2)create a symbolic link like so:
sudo ln -s /usr/share/maven3/bin/mvn /usr/bin/mvn
