设置Maven 3.0.4，win7的路径 [英] Setting up the path for Maven 3.0.4, win7

问题描述

我一直试图在我的计算机win 7上第一次安装Maven v 3.0.4.设置路径环境时遇到问题系统变量我有以下4个条目:

I have been trying to install Maven v 3.0.4 on my machine win 7 for the first time.I have a problem setting the path environment System variable I have the following 4 entries :

PATH
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04;C:\Program Files\apache-maven-3.0.4\bin;M2_HOME;%M2%


M2_HOME
C:\Program Files\apache-maven-3.0.4\bin

M2
%M2_HOME%\bin

JAVA_HOME
C:\Program Files\Java\jdk1.7.0_04\bin

当我做mvn --version

我得到了错误:

JAVA_HOME not found in your environment, please set the JAVA_HOME variable in your environment to match the location of your java installation

java -version可以正常显示Java版本，

The java -version displays the java version fine,

我到底在做什么错呢?路径没问题吗?

what am I doing so horribly wrong? Is the PATH ok?

感谢您的帮助，谢谢.

推荐答案

仅需要正确设置Maven二进制文件和JDK的路径:

It is only necessary to set the path to the Maven binary and to the JDK correctly:

set PATH %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04\bin;C:\Program Files\apache-maven-3.0.4\bin

此外，您需要正确设置JAVA_HOME，这是在像这样的窗口下完成的:

Furthermore you need to set the JAVA_HOME correctly which is done under windows like this:

SET JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04

请注意将JAVA_HOME设置为已安装JDK的根目录，而不是将其bin文件夹. 不需要设置M2和M2_HOME.

Be aware of setting JAVA_HOME to the root of the installed JDK and not to bin folder it. The settings of M2 and M2_HOME is not necessary.
