我无法启动我的 STS 3.3。它无法通过给出以下异常开始

!ENTRY org.eclipse.osgi 4 0 2013-09-30 10:22:40.079

这通常是插件保存的临时文件的问题。这些步骤应该可以帮助您：

  • 检查YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.jdt.core/有很多索引文件。有时删除它们会有所帮助。还可以使用-clean.
  • 根据您的问题，我认为您已经从文件系统中移动了一些文件，可能是一个新位置，这导致了这个错误。尝试检查它们。
  • 刷新所有项目。
  • 尝试创建一个新的工作区并检查。
  • 如果没有任何效果，请尝试重新安装它。

此外，如果您决定不使用 STS，您可以随时使用带有 STS 插件的 Eclipse IDE。

希望能帮助到你。:)
