安装 Maven [英] Installing Maven

问题描述

我无法正确安装 Maven 3.0.3.我已阅读 无法在 Windows 上安装 Maven:"JAVA_HOME 设置为无效目录" 但没有一个答案能够解决我的问题.

I am having trouble getting Maven 3.0.3 to install properly. I have read over Unable to install Maven on Windows: "JAVA_HOME is set to an invalid directory" but none of the answers were able to solve my problem.

这就是我所做的:

• 去http://maven.apache.org/download.html下载apache-maven-3.0.3-bin.zip
• 解压文件到 C:Program Files，所以我现在有一个名为 apache-maven-3.0.3 的目录
• 进入我系统的环境变量并创建用户变量M2_HOME，值为C:Program Filesapache-maven-3.0.3in
• JAVA_HOME变量设置正确，可以从命令行获取版本
• 编辑了 PATH，所以现在的值为 %SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;%SYSTEMROOT%System32WindowsPowerShellv1.0;C:Program FilesTortoiseHg;%JAVA_HOME%;%M2_HOME%

• Went to http://maven.apache.org/download.html and downloaded apache-maven-3.0.3-bin.zip
• Extracted files to C:Program Files, so I now have a directory called apache-maven-3.0.3
• Went to my system's environment variables and created user variable M2_HOME, value is C:Program Filesapache-maven-3.0.3in
• JAVA_HOME variable is set properly, can get version from cmd line
• Edited PATH so the value is now %SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;%SYSTEMROOT%System32WindowsPowerShellv1.0;C:Program FilesTortoiseHg;%JAVA_HOME%;%M2_HOME%

当我进入 cmd 时，我得到的是这样的:

When I go to cmd, I this is what I get:

   D:>java -version
    java version "1.6.0_25"
    Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
    Java HotSpot(TM) 64-Bit Server VM (build 20.0-b11, mixed mode)

    D:>mvn --version
    'mvn' is not recognized as an internal or external command,
    operable program or batch file.

但是，如果我实际上在目录中，我可以执行以下操作:

However, if I am actually in the directory I can do the following:

D:>cd C:Program Filesapache-maven-3.0.3in

D:>C:

C:Program Filesapache-maven-3.0.3in>mvn --version
Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
Maven home: C:Program Filesapache-maven-3.0.3
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Java home: C:Program FilesJavajdk1.6.0_25jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

这实际上应该如何工作?据我所知，我不应该在这样的目录中使用任何 mvn 命令.感谢您的宝贵时间！

Is this how it should actually work? From what I have been told I should not have to be in the directory like that to use any mvn commands. Thank you for your time!

推荐答案

请记住这两点:

• 任何文件系统路径包含之间的空格应该是用双引号括起来.例如set M2_HOME="C:Program Filesapache-maven-3.0.3"
• PATH 应该包含目录您的可执行文件所在的位置.如果 M2_HOME 是您的 C:Program Filesapache-maven-3.0.3，则 PATH 应该是 %M2_HOME%垃圾箱

• Any filesystem path containing whitespaces in between should be surrounded with double quotes. e.g. set M2_HOME="C:Program Filesapache-maven-3.0.3"
• PATH should contain the directory in which your executable exists. If M2_HOME is your C:Program Filesapache-maven-3.0.3, the PATH should be %M2_HOME%in
