如何在Windows中安装Maven？

您好我只是下载maven二进制文件并在设置了所有环境变量之后,我正在运行mvn -versioncmd并获得此异常.

Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.codehaus.plexus.util.Os.OS_NAME from class org.apache.maven.cli.CLIReportingUtils at org.apache.maven.cli.CLIReportingUtils.showVersion(CLIReportingUtils.

在这里下载Maven .

解压缩,例如: C:\tools\

按Windows+ R,键入systempropertiesadvanced,按Enter

设置环境:MAVEN_HOME=C:\tools

添加到PATH环境变量:;%MAVEN_HOME%\bin

关闭所有

调用cmd,运行命令:

mvn -v
