Maven 2 links

This document is intended as a quick reference of some of m2 aspects. If you are not yet comfortable with M2 you should check Maven2 guides. There is also a great Maven 2 book: Better Builds with Maven. The book is for free but it requires a registration.

Finding dependencies

There are two sites you may use to find libraries:

You may of course just google for artifact-id site:www.ibiblio.org/maven2 :)

Maven 2 repositories

Maven repository is a HTTP website containing various jars and their descriptors. There are some maven repositories out there:

  • http://repo1.maven.org/maven2/ - the primary Maven2 repository, maintained by the Maven2 crew. Implicitly used by maven 2, you don't have to add it into the settings.xml file.
  • http://www.ibiblio.org/maven2/ - a BIG repository of nearly all java libraries
  • http://maven.sateh.com/repository - a mirror located in Amsterdam, Europe. Quite a fast mirror, I must say
  • http://julien.dubois.free.fr/maven2/ - fearlessly contains some SUN proprietary libraries which cannot be hosted on an official repository
  • http://dist.sourcelabs.com/sash/m2 - contains Eclipse plugins jars
  • delo.dcs repository - an experimental repository hosted on Comenius University Bratislava. Contains libraries developed by the Baka.sk crew, and some eclipse plugins.

    If you are behind a proxy please see this maven proxy guide. You have to put the settings.xml file into $HOME/.m2 directory and add the repository. To add a repository to maven edit the $HOME/.m2/settings.xml file and add the following profiles section:

    <settings>
 
 ...
 
 <profiles>
   <profile>
     <id>default</id>
     <repositories>
       <repository>
         <id>ibiblio</id>
         <name>www.ibiblio.org</name>
         <url>http://www.ibiblio.org/maven2</url>
       </repository>
     </repositories>

     <!-- add this to register a plugin repository -->
          <pluginRepositories>
            <pluginRepository>
         <id>baka</id>
         <name>baka.sk</name>
         <url>http://delo.dcs.fmph.uniba.sk/sioux/maven2</url>
       </pluginRepository>
          </pluginRepositories>
   </profile>
 </profiles>
 <activeProfiles>
   <activeProfile>default</activeProfile>
 </activeProfiles>
 
 ...
 
</settings>

    Please note that the <id> element must not contain characters such as path_separator (/), colon : etc. Try to use alphanumeric characters only.
