使用 Repast Simphony 2.0 eclipse 在关闭透视图和关闭应用程序后不再打开

Question

StackOverflow 的新手，如果我违反了约定，请告诉我。我已经搜索了论坛，但找不到任何关于我的问题的帮助，所以这里......

我正在使用 Repast Simphony（2.0 版）并且遇到了可怕的 Eclipse 崩溃，这意味着 Eclipse 现在根本拒绝打开。我记得的事件顺序是这样的：

1. 我注意到特定包不再显示在 Eclipse Package Explorer 透视窗口中（在主窗口的左侧。
2. 我尝试关闭并重新打开透视图，但没有任何乐趣。
3. 我尝试了“窗口”菜单上的“关闭所有透视图”选项，假设我可以从头开始重新打开透视图。
4. 无法重新打开透视图，因此我关闭了应用程序。
5. Eclipse 将不再打开。
6. 检查了日志文件，有一个异常被复制到帖子末尾。

如果我能在我的项目完好无损的情况下再次打开 Eclipse，我将不胜感激。

Answer 1

对我来说，帮助将 Repast Simphony 文件夹 /plugins/repast.simphony.relogo.ide_2.0.0 移动到安全的地方，重新启动 eclipse，将文件夹移回原来的位置 /plugins 并再次启动 eclipse。

Answer 2

您可以尝试将 /.metadata/plugins/org.eclipse.ui.workbench/workbench.xml 移动到安全位置（以防万一）并启动 Eclipse。然后应该使用默认设置重建工作台布局。
