mvn command is not recognized as an internal or external command

Question

I am getting the mvn command not recognized as an internal or external command.

I have setup the M2_HOME, JAVA_HOME and added %M2_HOME%/bin to the path

Answer 1

I had this same error but my problem was I had the following:

M2_HOME = C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;

Which meant my PATH = %M2_HOME%\bin; (etc)

...became C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;\bin

i.e. a semicolon was where it shouldn't be.

Which I discovered because Michael Ferry suggested using 'ECHO %PATH%' to see what the actual PATH output was.
