"org.eclipse.wst.validation" has been removed

導出maven工程遇到的問題，"org.eclipse.wst.validation" has been removed，還以為是工程本身的問題，后來發現是eclipse的問題。

 

解決辦法：

 把D:\kaola\kaolaWorkSpace\.metadata\.plugins\org.eclipse.core.runtime\.settings 下的org.eclipse.wst.validation.prefs 刪除就可以了

參考以下解決辦法，未能解決：

Same probleme here, there the solution I fix it

• Open the .project file with your prefered text editor.

• delete the node that is about "org.eclipse.wst.validation"

• Close your project

• Open your project

• Launch Maven Update...

Should be good.

Another way to fix it, if you don't want to change your .project config (or if you had several projects that must be fixed)

• Close your workspace (or eclipse)

-move out <WorkspaceDir>\.metadata\.plugins\org.eclipse.core.resources\.projects from the workspace directory

-reopen you workspace

• close it again

-move back the .projects dir (say yes to replace questions ? )

• open you workspace

• Launch Maven Update

Should be good

 

參考以下答復，解決問題：

It appears that deleting the file org.eclipse.wst.validation.prefs in the directory .metadata/.plugins/org.eclipse.core.runtime/.settings (default settings for workspace) or .settings in each individual project will cause the settings for validation to be reset to their original settings. You can then use validation without getting error messages and try resetting the options from there. However, I'm not sure what combination of settings would cause the problem to reappear. However, if it does, you can repeat the process.
