I also successfully tested a connection to an external URL behind a proxy using
this test program:
public class TestProxy {
public static void main(String[] args) throws Exception {
System.setProperty("http.proxyHost", "<host>");
System.setProperty("http.proxyPort", "<port>");
URL u = new
URL("http://repo1.maven.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom";);
URLConnection c = u.openConnection();
c.connect();
}
}
When a proxy host/port is not set then I'm getting an UnknownHostException.
Setting a network proxy in Archiva or for the whole JVM (via -Dhttp.proxyHost
and -Dhttp.proxyPort) has no effect...

Subject: Network proxy doesn't work (UnknownHostException)
Hello,
I'm getting an UnknownHostException when trying to access an artifact from a
remote repository via Archiva:
central: Download failure on resource
[http://repo1.maven.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom]:Error
transferring file: repo1.maven.org (cause: java.net.UnknownHostException:
repo1.maven.org)
org.apache.maven.archiva.policies.ProxyDownloadException: Failures occurred
downloading from some remote repositories:
central: Download failure on resource
[http://repo1.maven.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom]:Error
transferring file: repo1.maven.org (cause: java.net.UnknownHostException:
repo1.maven.org)
The URL:
http://<hostname>:8080/archiva/repository/internal/junit/junit/3.8.1/junit-3.8.1.jar<http://%3chostname%3e:8080/archiva/repository/internal/junit/junit/3.8.1/junit-3.8.1.jar>
I configured proxy settings under "Network Proxies" (Archiva is running behind
a corporate proxy).
I'm able to access the artifact directly (from the same machine where Archiva
is running):
http://repo1.maven.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom
The same proxy configuration works both in Nexus and when using Maven
Repository Manager.
Apache Archiva (version 1.3.5) is running off Tomcat 7.0.12 on Windows Server
2008 Enterprise (SP2).
Has anyone encountered this issue?
Thanks,
Lukasz
