Myeclipse struts2 model load fail

Yesterday, I worked very hard to compile the code. I used myeclipse and didn't install any software or other things. It worked very well all day. It was also very useful in the past. Today, a strange thing happened. Once myeclipse is enabled, an error is reported. Other functions can be used. I didn't care about it at first. I continued to write my code. However, struts needs to be enabled at last. Xml. When I add something to it, I find that the file cannot be opened. The error message "struts2 model loading error" is displayed. The specific English prompt cannot be remembered. This should be the case when translating Chinese characters.

Why? I found it online and couldn't find it. In a sigh of relief, I uninstalled and reinstalled myeclipse, which is still the same. I feel this error is dropping from the sky without any warning.

It took me a lot of time to reinstall myeclipse and set it.

What should we do? I changed the project location. It was strange that the myeclipse startup error was not prompted. It is estimated that the project file may be damaged. It is not clear how the project is damaged.

If you encounter any problems in the future, never reload them. After all, myeclipse has been used for so long and it takes some time for some configurations to be re-implemented. For example, a package version of its built-in struts2 is lower than that of hibernate, and it needs to be deleted, very troublesome. I used it now. I haven't made lunch yet. Whow.

Remember Later, if there is such an error, do not reinstall it, try to change the location, find this error.

I don't know if anyone has the same error as me.
