Same probleme here, there the solution I fix it

同样的问题在这里，我修复它的解决方案

• Open the .projectfile with your prefered text editor.

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

• Close your project

• Open your project

• Launch Maven Update...

• .project使用您喜欢的文本编辑器打开文件。

• 删除关于“org.eclipse.wst.validation”的节点

• 关闭你的项目

• 打开你的项目

• 启动 Maven 更新...

Should be good.

应该不错。

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)

另一种修复方法，如果您不想更改 .project 配置（或者如果您有几个必须修复的项目）

• Close your workspace (or eclipse)

• 关闭您的工作区（或日食）

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

-<WorkspaceDir>\.metadata\.plugins\org.eclipse.core.resources\.projects从工作区目录中移出

-reopen you workspace

- 重新打开你的工作区

• close it again

• 再次关闭它

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

- 移回 .projects 目录（说是来替换问题？）

• open you workspace

• Launch Maven Update

• 打开你的工作区

• 启动 Maven 更新

Should be good

应该不错

I was using Eclipse Mars and in my case, just close and reopen my IDE did the work.

我正在使用 Eclipse Mars，就我而言，只需关闭并重新打开我的 IDE 即可完成工作。

Dont know, if you still have this problem, but here is the solution worked for me:

不知道，如果你仍然有这个问题，但这是对我有用的解决方案：

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.

似乎删除目录 .metadata/.plugins/org.eclipse.core.runtime/.settings（工作区的默认设置）或 .settings 中的文件 org.eclipse.wst.validation.prefs 将导致验证设置重置为其原始设置。然后您可以使用验证而不会收到错误消息并尝试从那里重置选项。但是，我不确定哪种设置组合会导致问题再次出现。但是，如果是这样，您可以重复该过程。

in my case i didnt have the mentioned file in this folder, but i had a bunch of other org.eclipse.wst.* files. deleting them all did the trick for me.

就我而言，我在这个文件夹中没有提到的文件，但我有一堆其他 org.eclipse.wst.* 文件。删除它们都对我有用。

Another Solution is too simple , deleting .project file then clean the project and maven update will success surely

另一个解决方案太简单了，删除.project文件然后清理项目，maven更新肯定会成功

回答by CCC

The problem is not related to the .projectsfolder as mentioned in another answer. The solution is to add a file called org.eclipse.wst.validation.prefsin the .settingsfolder. This will restore the eclipse validation node.

该问题与.projects另一个答案中提到的文件夹无关。解决方法是org.eclipse.wst.validation.prefs在.settings文件夹中添加一个名为的文件。这将恢复 eclipse 验证节点。

The content of the file, depending on your eclipse version, might look like this:

根据您的 eclipse 版本，文件的内容可能如下所示：

disabled=06target
eclipse.preferences.version=1

I think this is one error that could be caused by multiple different sources. I just had the same error however, and just figured out why. In my situation, I just tried to force update some code by deleting a few temporary files. Turned out I accidentally deleted that file as well. I thankfully had it under source control, so I pulled the file back and updated the project with Maven. I also made sure any other errors were fixed so that the project would clean / update successfully.

我认为这是一个可能由多个不同来源引起的错误。然而，我只是遇到了同样的错误，只是想出了原因。在我的情况下，我只是尝试通过删除一些临时文件来强制更新一些代码。原来我不小心删除了那个文件。幸运的是，我将它置于源代码控制之下，因此我将文件拉回并使用 Maven 更新了项目。我还确保修复了任何其他错误，以便项目成功清理/更新。

I'm not sure if this will solve your problem, but I hope it helps! Good luck!

我不确定这是否能解决您的问题，但我希望它有所帮助！祝你好运！
