java - Maven not working on windows -

-

when ran mvn -v, didn't version. got following 

c:\>mvn -v usage: java [-options] class [args...]            (to execute class)    or  java [-options] -jar jarfile [args...]            (to execute jar file) options include:     -cp <class search path of directories , zip/jar files>     -classpath <class search path of directories , zip/jar files>                   ; separated list of directories, jar archives,                   , zip archives search class files.     -d<name>=<value>                   set system property     ......

i believe set path correct. here path

c:\>path path=c:\java7\bin;c:\maven\apache-maven-3.3.3\bin  c:\>echo %java_home% c:\java7  c:\>java -version java version "1.7.0" java(tm) se runtime environment (build pwa6470sr8fp10-20141219_01(sr8 fp10))ibm j9 vm (build 2.6, jre 1.7.0 windows 7 amd64-64 compressed references 20141216_227497 (jit enablebled)

any idea did wrong?

set following environment variables. works me charm.

java_home - c:\program files\java\jdk1.7.0  m2_home-    d:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0  path-       c:\program files\java\jdk1.7.0\bin;d:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0\bin;  maven_home -d:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0

check mvn -v in command prompt.

c:\>mvn -v apache maven 3.1.0 (893ca28a1da9d5f51ac03827af98bb730128f9f2; 2013-06-28 07:45:32+0530) maven home: d:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0 java version: 1.7.0, vendor: oracle corporation java home: c:\program files\java\jdk1.7.0\jre default locale: en_us, platform encoding: cp1252 os name: "windows 7", version: "6.1", arch: "x86", family: "windows" c:\>
