playframework Debug模式 DuplicateMemberException

Question

过去几天我一直在运行我的游戏框架，并决定尝试 Debug模式。我只是运行 play eclipsify 并刷新我的 java 项目，然后右键单击 playtmp.launch 并运行为，然后“将 JPDA 连接到我的启动”并调试为并连接调试器(尽管我必须在 playtmp 中将挂起调整为“y”) .启动告诉)。

注意:每次启动时，我都会收到“项目中存在错误”，但“问题”选项卡中没有错误？？？

sooo，然后我进入了第一页，我得到了以下异常:( :( (上次我遇到这个问题是因为我把 play jar 放在 lib 文件夹中，这样我的 eclipse 就能编译，但我已经将它移出了那里，并且它可以与 play.bat 一起运行)

解答:我的启动文件是 playtmp.launch，而我的项目已重命名并作为 premonitionx checkin 到 CVS，因此它使用 eclipse 中另一个名为 playtmp 的项目。启动器仅适用于特定项目...如果您重命名它，您可能会被搞砸(我讨厌那样的环境)。
