昨晚打开Eclipse软件截图写了一篇博客，就关掉了软件，后来电脑也没有关机就去睡觉了，早晨点击Eclipse发现，人工呼吸也不能救活了。
出现这个弹框：
查看.log日志文件也不是很懂：

由于不清楚Eclipse打不开的原因，所以就查找各种解决方法，发现并不管用
最粗暴有效的解决方法:
1.可以选择重新安装Eclipse，解决100%问题
2.如果还有Eclipse安装文件，可以选择重新建一个文件夹作为Workspaces，然后再重启Eclipse，也能解决问题
但是我不想错过这样一个锻炼自己解决错误的机会，所以上面简单粗暴的方法，我并没有采用
先总结一下失败的方法：
网上查到我尝试的方法
查看log文件，发现有这样的信息： !MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes. 解决方案： 删除\.metadata\.plugins\org.eclipse.core.resources\*.snap这个文件， 重启Eclipse，会成功。
失败原因：我对应文件夹里面没有这个文件
查看log文件，发现有这样的错误信息： !MESSAGE FrameworkEvent ERROR 解决方案：cmd命令进eclipse，运行命令 eclipse.exe -clean后会自动打开软件，启动成功
失败原因：提示eclipse.exe -clean不是内部命令，Eclipse更没有自动打开
eclipse版本太新会出现这样的问题， 解决方法： 1，打开eclipse安装目录下的eclipse.ini文件； 2，打开的文本文件最后添加一行 --add-modules=ALL-SYSTEM 3，保存重新打开Eclipse。
失败原因：Eclipse依然打不开，并且.ini文件添加的内容在我重新打开Eclipse的时候自动消失了
1.打开eclipse工作空间D:\eclipse\workspace\.metadata\.plugins\org.eclipse.core.resources找到.projects文件 2.打开.projects文件，删除该目录下所有工程里的.markers.snap和.syncinfo.snap文件 3.再次启动eclipse就OK了！
失败原因：.projects文件下所有工程里只找到了.markers文件，删除后Eclipse依然打不开
将configuration\org.eclipse.osgi\.manager路径下的.fileTableLock删除， 重新启动就正常了。
失败原因：这种原因解决成功是因为Eclipse没有正常关闭导致的锁了，很明显我的不是这个原因，再次失败。
当然还有一些是因为jdk版本的问题，我没有动我的jdk所以应该不是这个问题了
好了，说一下我是怎么解决的，经历过上面的种种操作，我把电脑关机，上午关机一直到晚上才打开，点击Eclipse发现可以打开了，我也懵逼中，所以建议大家节省时间，去用简单粗暴的方法
