我在Eclipse中尝试启动Haskell项目时遇到错误。
以下是错误详情：
The selected wizard could not be started.
Plug-in net.sf.eclipsefp.haskell.ui was unable to load class net.sf.eclipsefp.haskell.ui.wizards.NewHaskellProjectWizard.
An error occurred while automatically activating bundle net.sf.eclipsefp.haskell.ui (504).
我有什么想法可以解决它？
