Eclipse Oxygen和Scala IDE 4.7与play framework 2.6.6项目在工作区中崩溃

Question

当Play/Maven项目处于工作区时，我的eclipse ide或scala ide（直接从scala站点下载）有两种情况会崩溃。

问题是：

1）安装Scala IDE 4.7。导入现有的Play/Maven项目。注意到IDE错误日志中的Scala编译器错误。重新启动时，您会发现eclipse不能引导相同的工作区。它可以引导其他工作区。即使我从play-maven项目中删除所有eclipse文件(.settings、.classpath、.project)，它也会崩溃。只有soln从工作区删除。元数据并重新导入项目。但下次重新启动后，问题再次发生。

2）安装Eclipse氧气。导入现有的Play/Maven项目。安装Scala IDE4.7插件，该插件需要Eclipse重新启动。重新启动时，该工作区将崩溃。

PS-正如我在上面提到的，如果我选择任何其他没有play-maven项目的工作区，eclipse/scala-id启动良好。

如果我需要分享任何其他细节，请告诉我。

我不知道您所说的“安装eclipse Oxyow”是什么意思，但我认为如果出现这种问题，最好从这里下载Scala IDE http://scala-ide.org/download/sdk.html作为zip并解包。希望能有所帮助
