我好几天都遇到这个问题。有时 Eclipse 工作正常，但有时 Eclipse 无法启动。可能是工作区出了问题，当我更改工作区时，它工作正常。但为什么它无法在我的旧工作区启动呢？
我也尝试解决方案 1，但没有任何成功。
当我启动 Eclipse 时它看起来像这样
但过一段时间它就会变成这样
我在 /workspace/.metadata/.log 文件中发现错误

答案1
删除元数据是一种非常激进的方式——本质上，它会杀死工作区（这就是为什么您需要重新导入项目）。
一个更温和的方法是使用-干净的旗帜：
eclipse -clean
答案2
转到你的工作区目录并删除'.metadata'目录并重新启动你的 eclipse。
它将重置你的 Eclipse 设置，一旦启动，将工作区切换到你的工作区并再次导入你的项目
答案3
尝试在终端中执行此命令。然后启动 eclipse。
命令：
rm -r ~/.eclipse
答案4
我认为您面临的问题和我一样。原来是默认工作区出了问题。如果我删除默认工作区（/home/<name>/workspace），然后启动 eclipse，那么一切都会正常。因此，我将默认工作区更改为其他地方，效果很好。
在 Eclipse 中，转到
文件 >切换工作区并在某处创建另一个工作区...窗口 > 首选项 > 常规 > 启动和关机 > 工作区然后在最近的工作区窗口中，删除默认工作区并应用新创建的工作区
希望这可以帮助
