问题描述

我的机器上安装了maven 3.3.1和java 1.7，Windows 8.1。

I have maven 3.3.1 and java 1.7 installed on my machine, windows 8.1.

MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75
Path=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%MAVEN_HOME%\bin;

我试图访问mvn命令行，在C：\ Users \ {myusername}下>，它运作良好：

I've tried to access mvn command line, under C:\Users\{myusername}>, it works well:

C:\Users\{myusername}>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

C:\Users\{myusername}>mvn -version
Apache Maven 3.3.1 (cab6659f9874fa96462afef40fcf6bc033d58c1c; 2015-03-13T13:10:2
7-07:00)
Maven home: C:\Program Files\Apache\apache-maven-3.3.1\bin\..
Java version: 1.7.0_75, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.7.0_75\jre
Default locale: en_US, platform encoding: GBK
OS name: "windows 8.1", version: "6.3", arch: "amd64", family: "windows"

但是当我改变了命令路径为D：，我机器中的另一个磁盘，输出变为：

But when I change the command path to D:, another disk in my machine, the output becomes:

D:\>mvn --version
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -d32          use a 32-bit data model if available
    -d64          use a 64-bit data model if available
    -server       to select the "server" VM
    -hotspot      is a synonym for the "server" VM  [deprecated]
                  The default VM is server.

D:\>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

除此之外当我使用Intellij创建maven项目时，就像quickstart一样，发生了类似的错误：

Besides, when I use Intellij to create maven project, just like quickstart, the similar error happened:

-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.[ERROR] Maven execution terminated abnormally (exit code 1)

我尝试过像mvn -version，mvn -d。但他们仍然无法工作。
有人可以帮忙吗？谢谢!!

I've tried like mvn -version, mvn -d. But they still do not work.Could anyone please help? Thanks!!

更新：
现在我的环境变量设置为：

Updated:Now my environment variables is set to:

JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75;
CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
M2_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
PATH=%JAVA_HOME%\bin;%M2_HOME%\bin;{others...}

问题仍然存在。

更新：

每当我输入mvn命令后D：路径，命令行只返回java提示;似乎忽略了mvn之后的所有事情。
就像这样：

Whenever I type after mvn command in D: path, the command line will just return java hint; it seems all the things after mvn are ignored.Just like this:

D:\>mvn fewadsfe
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -d32          use a 32-bit data model if available
    -d64          use a 64-bit data model if available
    -server       to select the "server" VM
    -hotspot      is a synonym for the "server" VM  [deprecated]
                  The default VM is server.

    -cp <class search path of directories and zip/jar files>

    -version      print product version and exit

推荐答案

我和Maven 3.3.1有同样的问题，但是当我尝试3.2.5版时问题得到解决。我不知道Windows 7/8和maven 3.3.1有什么问题。

I had the same issue with Maven 3.3.1 but when I tried version 3.2.5 the problem fixed. I don't know what's wrong with windows 7/8 and maven 3.3.1.
