I recently installed the Sonatype OSS 3.14.0-04. I new to nexus and I am creating roles stuff. I have seen nexus 2, but I did not have any involvement in setting it up or administrative work. What I seem to be having issues with now is deleting assets as the default admin. I added a package to the hosted maven-snapshot repo and I want to delete it using the GUI. When I click on Browse this is all I see. I did read the old post here in stackoverflow How to delete a Sonatype Nexus OSS(3) Component from a Repository. But the user was able to see The components under browse.
If you click into the repository you uploaded it to, you should get a list view of all components and assets within that repository.
If you click on the item you want to delete or if it's a folder, the contents of the folder you should be able to delete them from there.
See https://help.sonatype.com/display/NXRM3/Browsing+Repositories+and+Repository+Groups for more information (specifically the last screenshot shows the delete asset button).
