选择要启动的工作空间后，弹出一个窗口，显示“发生了错误。请参阅日志文件* my_work_space.metadata.log”

日志为：

搜索了一段时间后，我找到了一种在命令行中启动它的方法：

.\eclipse.exe -data C:\*\my_work_space

但是，我不想永远以这种方式启动它。任何帮助表示赞赏！

环境：

  • Windows 10 64位
  • Eclipse 2018-12（4.10.0）

eclipse.ini：

-startup
plugins/org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar
--launcher.library

-product
org.eclipse.epp.package.jee.product
-showsplash
org.eclipse.epp.package.common
--launcher.defaultAction
openFile
--launcher.appendVmargs

2 个答案:

答案 0 :(得分：5)

从eclipse.ini文件中注释以下行。

  

-Dosgi.dataAreaRequiresExplicitInit = true

答案 1 :(得分：1)

我突然对Eclipse 2020-06犯了同样的错误。在关闭Eclipse并重新打开相同的工作空间之后，发生了相同的错误。在Bug 540316中，我找到了使用“ -clean”选项开始蚀的提示。

因此，通过eclipse.exe -clean开始蚀似乎可以解决问题，至少我可以重新打开工作空间。但是我不知道是什么原因导致此问题及其解决方案。
