  <p>I have installed OpenJDK 7 and it runs well on my Ubuntu 14.04 machine. I want to add Java sources to my Eclipse. When I go to <code>/usr/lib/jvm/java-7-openjdk-amd64</code> there is a symlink called <code>src.zip</code> but it's broken. How do I fix this? Do I have to manually download sources and add them? </p>
