gen already exists but is not a source folder

Question

I am developing my Android project, After I removed a unused library, I got the error:

myproject/gen already exists but is not a source fold         


        

Answer 1

I get the same problem.

Two actions, first:

1.Right click on the project and go to "Properties"

2.Select "Java Build Path" on the left

3.Open "Source" tab

4.Click "Add Folder..." and check "gen" and "src"

second: (because the previous action asked me to remove something... I do not remember what it was...)

1. Right click on the project and go to "Properties"

2. Select "Java Build Path" on the left

3. Open Libraries "tab"

4. Add an external JAR. Add the Google API that is in your android directory (android-sdk\platforms\android-yourversion

And now it works for me!

Answer 2

I had SVN configured for a project with the same problem, deleted all folders and files, retrieved it again from SVN and still no luck. The only thing that helped was reverting the changes, and deleting/re-importing projects to the workspace. Hope this helps

Answer 3

The last time I had this issue, it was because I switched the source to another branch behind the scenes. Once I closed Eclipse and relaunched, the issue went away.
