Eclipse编辑器在编辑Xtend文件时保持挂起状态（'；更新编辑器状态（休眠）'；）
最近，我的Eclipse编辑器在编辑Xtend文件时开始变得非常迟钝。我在Xtext框架的上下文中使用Xtend（它使用Xtend提供某些接口）。我认为这与我的Eclipse安装有关，所以我将它完全从MacBook上删除，并重新安装了最新版本（Eclipse 2019-09）。然而，它在编辑Xtend文件时仍然非常缓慢。它每隔几秒钟执行一次（加载图出现，它挂起几秒钟，然后重复此序列）。我注意到Eclipse编辑器中的进度选项卡在停止挂起后显示消息“更新编辑器状态（睡眠）”。这种情况只发生在Xtend文件中（其他文件，如java，在Eclipse中工作正常，无需挂起）。我正在使用的Xtend文件目前大约有500行代码。不是一个小文件，但这可能是我的EclipseIDE一直挂起的原因吗？我已经尝试解决这个悬而未决的问题：Eclipse编辑器在编辑Xtend文件时保持挂起状态（'；更新编辑器状态（休眠）'；）,eclipse,eclipse-plugin,xtext,xtend,Eclipse,Eclipse Plugin,Xtext,Xtend,最近，我的Eclipse编辑器在编辑Xtend文件时开始变得非常迟钝。我在Xtext框架的上下文中使用Xtend（它使用Xtend提供某些接口）。我认为这与我的Eclipse安装有关，所以我将它完全从MacBook上删除，并重新安装了最新版本（Eclipse 2019-09）。然而，它在编辑Xtend文件时仍然非常缓慢。它每隔几秒钟执行一次（加载图出现，它挂起几秒钟，然后重复此序列）。我注意到Eclipse编辑器中的进度选项卡在停止挂起后显示消息“更新编辑器状态（睡眠）”。这种情况只发生在Xte
- 在我的MacBook上完全删除并重新安装Eclipse（仅安装我需要的必要插件：Palladio PCM框架和Xtext框架）
- 为Eclipse环境及其VM提供额外内存（最多6000 MB）（使用Eclipse.ini文件中的内存参数（例如XmX））
- 挂起Eclipse环境中的所有验证器（禁用覆盖此选项）
