Only granted nx-repository-admin-*-*-* privileges to a new role can't upload a jar

Hi all,

I'm trying to upload a jar with a new role and a new user which granted this role.In the role I granted the privileges of nx-repository-admin-*,but the upload with mvn deploy was failed.Then I changed the user to admin of nexus,the upload is success.

At last,to my suprise,when I granted the  nx-repository-view-*,the upload with this new user is OK.

In my opinion，the nx-repository-view is relation to the web operation of nexus,so I want to know why this privileges must be granted when upload a jar to the nexus server,is this a bug?

BTW,if this is not a bug,I suggested to add some description about thease available privileges of the role page.It'll be helpful to know how to granted privileges can meet the demand of us.
