title: Purpose of the "Build Automatically" option in eclipse
body: <p>What is the purpose of <strong>Build Automatically</strong> option in <code>Eclipse</code> (<code>Project</code><em>--></em><code>Build Automatically</code>)? Mine will always be checked. But when ever I have some java code changes I still have to do a full build. I was told that it should always be checked. I don't see any benefit in doing so. Please somebody explain.</p>
