而且当我第一次在我的计算机中配置 Maven 时，我检查了 Maven 是否使用mvn --version命令正确配置并且工作正常。但是在重新启动我的计算机并检查 Maven 后是否正常工作。然后它说：

C:\Users\User Name>mvn --version
'mvn' is not recognized as an internal or external command,

Try the following steps:

尝试以下步骤：

1. Make sure you have connectivity (you can browse) (This kind of error is usually due to connectivity with Internet)

2. Download Maven and unzip it

3. Create a JAVA_HOMESystem Variable

4. Create an M2_HOMESystem Variable

5. Add %JAVA_HOME%\bin;%M2_HOME%\bin;to your PATHvariable

6. Open a command window cmd. Check: mvn -v

7. If you have a proxy, you will need to configure it

1. 确保您有连接（您可以浏览）（这种错误通常是由于与 Internet 连接）

2. 下载Maven并解压

3. 创建JAVA_HOME系统变量

4. 创建M2_HOME系统变量

5. 添加%JAVA_HOME%\bin;%M2_HOME%\bin;到您的PATH变量

6. 打开命令窗口cmd。查看：mvn -v

7. 如果您有代理，则需要对其进行配置

http://maven.apache.org/guides/mini/guide-proxies.html

1. Make sure you have .m2/repository(erase all the folders and files below)

2. If you are going to use Eclipse, You will need to create the settings.xml

8. 确保你有.m2/repository（擦除下面的所有文件夹和文件）

9. 如果您打算使用 Eclipse，您将需要创建 settings.xml

Maven plugin in Eclipse - Settings.xml file is missing

Eclipse 中的 Maven 插件 - Settings.xml 文件丢失

Try the following :

尝试以下操作：

1. Make sure you add M2_HOMEvariable to your environment variables. It looks like you might have set M2_HOMEtemporarily in a cmdwindow and not as a permanent environment variable. Also append M2_HOMEto the PATHvariable.

2. Go to the m2folder in your user directory.

   Example: On Windows, for user bot, the .m2directory will be under C:\Users\bot. Look for the settings.xmlfile in this directory and look for the repository url within this file. See if you are able to hit this url from your browser. If not, you probably need to point to a different maven repository or use a proxy.

3. If you are able to hit the repository url from the browser, then check if the repository contains the maven-resource-pluginversion 2.6. This can be found by navigating to org.apache.maven.pluginsfolder in the browser. It's possible that your pomhas hard-coded the dependency of the plugin to 2.6 but it is not available in the repository. This can be fixed by changing the depndency version to the one available in the repository.

1. 确保将M2_HOME变量添加到环境变量中。看起来您可能已经M2_HOME在cmd窗口中临时设置而不是作为永久环境变量。还附加M2_HOME到PATH变量。

2. 转到m2用户目录中的文件夹。

   示例：在 Windows 上，对于 user bot，.m2目录将在C:\Users\bot. settings.xml在此目录中查找文件并在此文件中查找存储库 url。看看您是否可以从浏览器中访问此 url。如果没有，您可能需要指向不同的 Maven 存储库或使用代理。

3. 如果您能够从浏览器访问存储库 url，请检查存储库是否包含maven-resource-plugin2.6 版。这可以通过导航到org.apache.maven.plugins浏览器中的文件夹找到。您可能pom已将插件的依赖项硬编码为 2.6，但它在存储库中不可用。这可以通过将依赖版本更改为存储库中可用的版本来解决。

This helped me: I created a new maven project which was working fine in my old workspace, but gave above errors in the new workspace. I had to do the following: - Open old workspace on Eclipse - open Preferences tab - Search Maven in filter - Copy the path for settings.xml from User Settings - User Settings - Switch to new workspace - Update the preferences - Maven - User Settings - User Settings path

这对我有帮助：我创建了一个新的 maven 项目，该项目在我的旧工作区中运行良好，但在新工作区中出现了上述错误。我必须执行以下操作： - 在 Eclipse 上打开旧工作区 - 打开首选项选项卡 - 在过滤器中搜索 Maven - 从用户设置复制 settings.xml 的路径 - 用户设置 - 切换到新工作区 - 更新首选项 - Maven - 用户设置- 用户设置路径

After the build is completed, all errors are resolved.

构建完成后，所有错误都解决了。

I had a similar problem in spring tool suite(sts). THE .m2 repository was not completely downloaded in the local system which is the reason why I was getting this error. So I reinstalled stsand deleted the old .m2 repository from the system and created a new mavenproject in stswhich downloaded the complete .m2 repository. It worked for me.

我在spring 工具套件（sts）中遇到了类似的问题。.m2 存储库未完全下载到本地系统中，这就是我收到此错误的原因。所以我重新安装了sts并从系统中删除了旧的 .m2 存储库，并在sts 中创建了一个新的maven项目，该项目下载了完整的 .m2 存储库。它对我有用。
