How to resolve:
1. By typing "where Java" in the command line, find all Java-related programs except the JDK directory, and delete them directly (usually under C:\WINDOWS\system32)
2. Out of memory, open Eclipse.ini in Eclipse directory and change the-xmx512m inside to-xmx256m
3. Check the environment variables, and place the JDK path in the path variable at the front (".;" at the beginning). Directly behind)
4. Check the environment variables, and place the JRE path in the JDK at the front (".;" At the beginning of the path variable. Directly behind)
5. Rumors of the almighty scheme (but not all-in-all): Copy the JRE directory under the JDK directory directly to the Eclipse directory
6. Delete file: [Workspace]/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi (This article thanked hundred Xiaofeng contribution, likes one!) )
