Here is my Gradle Tasks view:
There is a ThisProj project which is not in the eclipse workspace but it is in the Gradle Tasks. The problem was that while the project was in the workspace it appeared twice in this view so I removed it from the workspace in attempt to import it so it will show only once.
If the project is in the workspace I get 2 "open" icon directories with the same name. If it is not I get 1 "closed" icon directories like above. None of the tasks can be executed - they are all grayed out. How do I clean this list or remove the project?

Go to command prompt and
First:
run
gradle cleanEclipseto clean the Eclipse configuration completelyThen
gradle eclipseto rebuild the Eclipse configurationThis will clean the Gradle Tasks list
