To solve the problem: -click right botton on the project package you want to work on (run) -choose Run As -choose Run Configurations... -choose DocsConnectionPropsHelper - if in the Project box you see not correct title just remove it. Also remove anything what is in the Main Class box. -click Apply -the best option is to close Eclipse and reopen it to make sure that all the settings were configured It worked for me. Hopefully it will work for you too.

Your update indicates the issue is actually running the wrong project. To avoid that you may want to close projects you're not working on (right click them in package explorer and select close).

If you do need multiple projects open then when clicking the run icon (which defaults to re-run whatever was ran last among your open projects) make sure you have open in the editor window something that can be ran (and is from the project you want to run).

Then click the drop down arrow to the right of the icon. This will open up a small menu with options to change your build configurations or how it should run your program (i.e. as an application or on a server).
