我正在尝试为Windows 7配置maven 3.0.3。我在D盘根目录上有它。我真的很喜欢： 环境变量 - ＆gt;系统变量 - ＆gt; MAVEN_HOME = D \ apache-maven-3.0.3和系统变量 - ＆gt; PATH =％JAVA_HOME％\ BIN;％MAVEN_HOME％\ BIN。
I want to know if it's configured or there is some problem.
当我在命令行输入mvn --3.0.3时，它输出为：

我正在关注的教程说它应该打印出你安装的Maven版本，例如：
Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)
Maven home: D:\apache-maven-3.0.3\bin\..
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Java home: E:\Program Files\Java\jdk1.6.0_25\jre
Default locale: nl_NL, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
答案 0 :(得分：1)
尝试mvn -v或mvn --version。
可以看出-v或--version是要使用的选项参数（而不是版本号本身）。如果您查看打印输出的第一行，maven会通知您一个未知选项：
无法解析命令行选项：无法识别的选项： - 3.0.3
答案 1 :(得分：0)
尝试
mvn -version
要轻松使用maven，只需将其bin文件夹添加到PATH即可。
答案 2 :(得分：0)
- 3.0.3不是一个有效的目标，因此它会显示所有可能的maven参数。
尝试：
mvn install
这也应该给你一个错误。但是它应该开始下载一些文件。 之后，您的用户的个人目录中应该有一个.m2文件夹。
