I have an artifactory within a corporate network. I configured a http proxy for each remote repository. It doesn't work. How could I possibly find out why it doesn't work? Are there any log settings which I could tweak?
Using the same proxy within Firefox works just fine.
Artifactory 2 uses logback for logging, you can find its configuration in $ARTIFACTORY_HOME/etc/logback.xml
If you can access the repository through the browser, it's likely the problem is in your Maven configuration. If you've a proxy configuration defined, you'll need to ensure the proxy is set to exclude your internal http proxy server.
If you run Maven with the -X switch, it will give you more details on the connection attempts Maven is making.
Could you solve it?
It seems that issue comes from the remote repositories (e.g. repo1.maven.org) in combination with proxies. The remote repository server response is an 403 Forbidden, if I connect with wget. A request with Firefox delivers the requested file.
