安装Maven [英] Installing Maven

问题描述

我无法使Maven 3.0.3正确安装。我已阅读无法在Windows上安装Maven：JAVA_HOME设置为无效目录但是没有一个答案能够解决我的问题。

这就是我所做的：

• 要 http://maven.apache.org/download.html并下载apache-maven-3.0.3-bin.zip


• 将文件提取到C：\Program文件，所以我现在有一个名为apache-maven-3.0.3


• 进入系统的环境变量并创建用户变量 M2_HOME ，值为 C：\Program Files\\ \\apache-maven-3.0.3\bin


• JAVA_HOME 变量设置正确，可以得到版本从cmd行


• 已编辑 PATH ，所以该值现在是％SystemRoot％\system32;％SystemRoot ％;％SYSTEMROOT％\System32\Wbe m;％SYSTEMROOT％\System32 \ Windows \\ Windows \\ Windows \\ b $ b

当我去找cmd，我就是这样：

 code> D：\> java -version 
 java版本1.6.0_25
 Java（SE）运行时环境（build 1.6.0_25-b06）
 Java HotSpot （TM）64位服务器VM（构建20.0-b11，混合模式）
 
 D：\> mvn --version 
'mvn'不被识别为内部或外部命令，
可操作的程序或批处理文件。 
  

但是，如果我实际上在目录中，我可以执行以下操作：

  D：\> cd C：\Program Files\apache-maven-3.0.3\bin 
 
 D：\> C：
 
 C：\Program Files\apache-maven-3.0.3\bin> mvn --version 
 Apache Maven 3.0.3（ $ 10 
 Maven主页：C：\Program Files\apache-maven-3.0.3 
 Java版本：1.6.0_25， Sun Microsystems Inc. 
 Java home：C：\Program Files\Java\jdk1.6.0_25\jre 
默认语言环境：en_US，平台编码：Cp1252 
操作系统名称： Windows 7，版本：6.1，arch：amd64，family：windows
  

这是怎么实际工作的？从我被告知，我不应该在这样的目录使用任何mvn命令。谢谢你的时间！

解决方案

只要牢记这两件事：

• 其间包含
  的空格的任何文件系统路径应为
  ，用双引号括起来。例如设置M2_HOME =C：\Program Files\apache-maven-3.0.3


• PATH 应该包含您的可执行文件所在的目录
  。如果 M2_HOME 是您的 C：\Program Files\apache-maven-3.0.3 ， PATH 应为％M2_HOME％\bin

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.

This is what I did:

• 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 Files\apache-maven-3.0.3\bin
• JAVA_HOME variable is set properly, can get version from cmd line
• Edited PATH so the value is now %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\TortoiseHg\;%JAVA_HOME%;%M2_HOME%

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.

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

D:\>cd C:\Program Files\apache-maven-3.0.3\bin

D:\>C:

C:\Program Files\apache-maven-3.0.3\bin>mvn --version
Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
Maven home: C:\Program Files\apache-maven-3.0.3
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Java home: C:\Program Files\Java\jdk1.6.0_25\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

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!

解决方案

Just keep these two things in mind :

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