Answer 1

I had a similar problem:

enum can't be resolved to a type

Eclipse offered to import Enum instead.

I went to

• Preferences->Java->Installed_JREs->Execution_environment;
• Selected JavaSE-1.6 in "Execution Environments" pane; and
• Checked jre6 in Compatible JREs pane.

After rebuild enum was recognized properly.
