Eclipse.Error.gen already exists but is not a source folder.

在Eclipse ADT来开发Android App时会遇到以下问题:
"myproject/gen already exists but is not a source folder. Convert to a source folder or rename it"

解决办法是:

    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"
