I am having this problem in the image:

even if in the path displayed is correct and exists. I tryed anyway to change this variable and the files in C:\\Program Files\Java\apache-maven-2.2.1 or C:\\Program Files\Java\apache-maven-2.2.1\bin or C:\\Program Files\apache-maven-2.2.1\bin as I read in different forums.
My enviroment variables are set up as follow:
Path=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;%ROO_HOME%\bin;%M2_HOME%\bin;
M2_HOME=C:\Program Files\apache-maven-2.2.1
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_18
ROO_HOME=C:\spring-roo-1.1.0.RC1
Must I do something extra?
Thanks in advance
Actually, what I did was uninstall and reintall, the old ‘trick’.
Worked :s
