title: How do you build a Java project in Eclipse when no options are available
body: <p>I am trying to build a Java project I found on Github using Eclipse. The project has no maven &amp; gradle files and no .jar files in the repo. I am getting the following error when I try to build the project within Eclipse. "No actions available." Also, When I select the option, Right-click the project and choose Configure > Configure and Detect Nested Projects, this is not working. Please see the images attached. This is the current repo I am trying to run, <a href="https://github.com/copley/def-guide-to-java-swing.git" rel="nofollow noreferrer">https://github.com/copley/def-guide-to-java-swing.git</a></p>
