Getting 401 Access denied in Maven when downloading using artifactory

Hi,

I am using Maven to download artifactory which has credentials and i have to use proxy settings also. I created a master password for my real password and i sent it settings-security.xml. and I added this password in servers along with my ID.
But I am getting 401 access denied error and when i tried to download manually i am able to do it. please help me with this.
