1、先在命令行下进入Eclipse目录，执行 eclpise -clean，如果仍报错，尝试2.

2、在新安装了软件或者修改了环境变量容易出现这个问题，查看之前配置好的环境变量jdk路径是否出错，若无，将jdk bin 路径提前至 path的最前，然后打开Eclipse看能否正常进入。

3、如果执行前两条仍不奏效，你或许遇到了跟我一样的问题：你的jdk由于种种原因损坏了（之前Eclipse可用的话，说明版本没问题，一直无法打开Eclipse的童鞋也可能是jdk的版本问题），重进安装jdk即可解决该问题。

①删除/.metadata/.plugins/org.eclipse.core.resources/.snap(若执行了这个就解决的话，不需要第二个方法) 
②删除/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
