Try the following steps:

试试下面的步骤:

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

确保你有连接(你可以浏览)(这种错误通常是由于连接到互联网)
Download Maven and unzip it

下载Maven并解压它
Create a JAVA_HOME System Variable

创建一个JAVA_HOME系统变量。
Create an M2_HOME System Variable

创建一个M2_HOME系统变量
Add %JAVA_HOME%\bin;%M2_HOME%\bin; to your PATH variable

添加% JAVA_HOME % \ bin;% M2_HOME % \ bin。你的路径变量
Open a command window cmd. Check: mvn -v

打开命令窗口cmd。检查:mvn - v
If you have a proxy, you will need to configure it

如果您有一个代理，您将需要配置它

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

确保有.m2/储存库(删除下面所有文件夹和文件)
If you are going to use Eclipse, You will need to create the settings.xml

如果要使用Eclipse，需要创建settings.xml

Maven plugin in Eclipse - Settings.xml file is missing

Eclipse中的Maven插件-设置。xml文件丢失

#2

Delete all files under the .m2 repository folder and rebuild the project.

删除.m2存储库文件夹下的所有文件并重新构建项目。

#3

Try the following :

试试以下:

Make sure you add M2_HOME variable to your environment variables. It looks like you might have set M2_HOME temporarily in a cmd window and not as a permanent environment variable. Also append M2_HOME to the PATH variable.

确保将M2_HOME变量添加到环境变量中。看起来您可能暂时在cmd窗口中设置了M2_HOME，而不是将其作为永久环境变量。还将M2_HOME追加到PATH变量。
Go to the m2 folder in your user directory.

转到用户目录中的m2文件夹。

Example: On Windows, for user bot, the .m2 directory will be under C:\Users\bot. Look for the settings.xml file 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.

例子:在Windows上,对于用户机器人,将面临C:\Users\bot. .m2目录寻找的设置。此目录中的xml文件，并在此文件中查找存储库url。看看你是否能够从浏览器点击这个url。如果没有，您可能需要指向不同的maven存储库或使用代理。
If you are able to hit the repository url from the browser, then check if the repository contains the maven-resource-plugin version 2.6. This can be found by navigating to org.apache.maven.plugins folder in the browser. It's possible that your pom has 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.

如果您能够从浏览器中访问存储库url，那么请检查存储库是否包含maven-resource-plugin 2.6版本。这可以通过导航到org.apache.maven找到。浏览器中的插件文件夹。您的pom可能已经将插件的依赖性硬编码为2.6，但在存储库中不可用。可以通过将深度查询版本更改为存储库中可用的版本来修复这一点。

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

这对我很有帮助: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，但是在新的工作区中出现了上述错误。我必须做以下工作:-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 -复制设置路径。xml从用户设置-用户设置-切换到新的工作空间-更新首选项- Maven -用户设置-用户设置-用户设置路径

After the build is completed, all errors are resolved.

构建完成后，所有错误都得到解决。

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 sts and deleted the old .m2 repository from the system and created a new maven project in sts which downloaded the complete .m2 repository. It worked for me.

我在spring tool suite(sts)遇到了类似的问题。.m2存储库没有完全在本地系统中下载，这就是为什么我得到这个错误的原因。因此，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。它为我工作。
