Creating a Proxy repository on Nexus that proxies Oracle Maven Repo (http://download.oracle.com/maven/) marks the Oracle Repo as "Attempting to Proxy and Remote Unavailable"
The problem might be that Oracle disabled directory listing and every attempt to get the content without the full GAV returns a 404 code.
How to workaround this on Nexus?
Using Nexus OS Edition 1.9.2.2
Configuration:
Remote Storage Location = http://download.oracle.com/maven/
Download Remote Indexes = True
Auto Blocking Active = False
File Content Validation = True
CheckSum Policy = Warn
