Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'ProjectName'.

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上配置 Maven 时，我检查 Maven 使用 mvn --version 命令配置是否正确，它工作正常。但是在重新启动我的计算机并检查 Maven 是否正常工作之后。然后它说:

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

Answer 1

尝试以下步骤:

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

2. 下载Maven并解压

3. 创建一个JAVA_HOME系统变量

4. 创建一个M2_HOME系统变量

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

6. 打开命令窗口 cmd。检查:mvn -v

7. 如果您有代理，则需要对其进行配置

1. 确保你有 .m2/repository(清除下面所有的文件夹和文件)

2. 如果您打算使用 Eclipse，则需要创建 settings.xml

Maven plugin in Eclipse - Settings.xml file is missing
