I entered mvn command in windows, but the command line return a java hint

Question

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;

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

Default locale: en_US, platform encoding: GBK
OS name: "windows 8.1", version: "6.3", arch: "amd64", family: "windows"

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

D:\>mvn --version

           (to execute a class)
   or  java [-options] -jar jarfile [args...]

                  The default VM is server.

D:\>java -version
java version "1.7.0_75"

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)

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

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...}

And the problem still exists.

Updated:

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)

Answer 1

I had the same problem in Windows Server 2012 R2 with Apache Maven 3.6.0. It was a strange issue.

I had to delete C:\.mvn Folder and it worked!

Answer 2

I too have this problem with maven 3.3.1 and windows 7 and I have found this answer in a forum. In this version of maven there is a problem with the command line being issued in the root directory of a drive (c:\, d:\, ...). Issuing the command on any other directory works.
