当我尝试构建项目时，它会给出此错误。

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'ProjectName'.
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

我的Java版本是1.8，Maven版本是3.2.5

而且，当我第一次在我的计算机中配置Maven时，我检查Maven是否正确配置了命令，它工作正常。但是在重新启动计算机并检查Maven是否正常工作后。然后它说：mvn --version

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

答案 1

请尝试以下步骤：

确保您已建立连接（可以浏览）（此类错误通常是由于与 Internet 的连接造成的）
下载 Maven 并解压缩它
创建系统变量JAVA_HOME
创建系统变量M2_HOME
添加到变量%JAVA_HOME%\bin;%M2_HOME%\bin;PATH
打开命令窗口。检查：cmdmvn -v
如果您有代理，则需要对其进行配置

确保你有（删除下面的所有文件夹和文件）.m2/repository
如果您要使用 Eclipse，则需要创建settings.xml

Eclipse 中的 Maven 插件 - 设置.xml文件丢失

您可以在

答案 2

删除 .m2 存储库文件夹下的所有文件并重新生成项目。
