maven error transferring file blacklisted

Question

i cannot download artifacts from my nexus server through maven but i can access the urls from my browsers without proxy. I am getting

    java.net.ConnectException: Connection timed out:connect
       at java.net.PlainSocketImpl.socketConnect...
    Repository will be blacklisted

I am using maven 2.2.1

Answer 1

Try mvn -U to force updates, even if they are blacklisted.

Did you specify your repository in your pom.xml? It could be a DNS problem. Try to specify your repository with your IP instead of the hostname.

Answer 2

You may have forgotten to add repository credential in you settings.xml, if it require authentication (that you fulfill wia your browser, even whithout knowing it):

Settings.xml :

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  ...
  <servers>
    <server>
      <id>corporate-nexus</id>
      <username>login</username>
      <password>password</password>
    </server>
  </servers>
  ...
</settings>

pom.xml

<repositories>
    <repository>
      <id>corporate-nexus</id>
      <name>My Corporate repository</name>
      <url>http://url.to.your.repo.corp</url>
    </repository>
</repositories>

Be carefull, the id tags must have the same value.
