            &lt;p&gt;
              This element describes all of the dependencies associated with a
              project.  Each dependency is described by a
              &lt;code&gt;dependency&lt;/code&gt; element, which is then described by
              additional elements (described below).
            &lt;/p&gt;
            &lt;p&gt;
              These dependencies are used to construct a classpath for your 
              project during the build process.
            &lt;/p&gt;
            &lt;p&gt;
              Maven can automatically download these dependencies from a 
              &lt;a href="/user-guide.html#Remote%20Repository%20Layout"&gt;remote repository&lt;/a&gt;.
            &lt;/p&gt;
            &lt;p&gt;
              The filename that Maven downloads from the repository is 
              &lt;code&gt;artifactId-version.jar&lt;/code&gt; where &lt;code&gt;artifactId&lt;/code&gt; 
              corresponds to the &lt;code&gt;artifactId&lt;/code&gt; element and 
              &lt;code&gt;version&lt;/code&gt; corresponds to the &lt;code&gt;version&lt;/code&gt; element.
            &lt;/p&gt;
            &lt;p&gt;
              When Maven goes looking for a dependency in the remote repository, 
              it uses the dependency element to construct the URL to download 
              from. This URL is defined as:
            &lt;/p&gt;
            &lt;div class="source"&gt;
              &lt;pre&gt;${repo}/${groupId}/${type}s/${artifactId}-${version}.${type}&lt;/pre&gt;
            &lt;/div&gt;
            &lt;p&gt;
              Where
            &lt;/p&gt;
            &lt;dl&gt;
              &lt;dt&gt;repo&lt;/dt&gt;
              &lt;dd&gt;
                is the remote repository URL specified by 
                &lt;code&gt;${maven.repo.remote}&lt;/code&gt;
              &lt;/dd&gt;

            &lt;p&gt;
              This element describes all of the dependencies associated with a
              project.  Each dependency is described by a
              &lt;code&gt;dependency&lt;/code&gt; element, which is then described by
              additional elements (described below).
            &lt;/p&gt;
            &lt;p&gt;
              These dependencies are used to construct a classpath for your 
              project during the build process.
            &lt;/p&gt;
            &lt;p&gt;
              Maven can automatically download these dependencies from a 
              &lt;a href="/user-guide.html#Remote%20Repository%20Layout"&gt;remote repository&lt;/a&gt;.
            &lt;/p&gt;
            &lt;p&gt;
              The filename that Maven downloads from the repository is 
              &lt;code&gt;artifactId-version.jar&lt;/code&gt; where &lt;code&gt;artifactId&lt;/code&gt; 
              corresponds to the &lt;code&gt;artifactId&lt;/code&gt; element and 
              &lt;code&gt;version&lt;/code&gt; corresponds to the &lt;code&gt;version&lt;/code&gt; element.
            &lt;/p&gt;
            &lt;p&gt;
              When Maven goes looking for a dependency in the remote repository, 
              it uses the dependency element to construct the URL to download 
              from. This URL is defined as:
            &lt;/p&gt;
            &lt;div class="source"&gt;
              &lt;pre&gt;${repo}/${groupId}/${type}s/${artifactId}-${version}.${type}&lt;/pre&gt;
            &lt;/div&gt;
            &lt;p&gt;
              Where
            &lt;/p&gt;
            &lt;dl&gt;
              &lt;dt&gt;repo&lt;/dt&gt;
              &lt;dd&gt;
                is the remote repository URL specified by 
                &lt;code&gt;${maven.repo.remote}&lt;/code&gt;
              &lt;/dd&gt;
              
              &lt;dt&gt;groupId&lt;/dt&gt;
              &lt;dd&gt;is taken from the dependency element&lt;/dd&gt;
              
              &lt;dt&gt;type&lt;/dt&gt;
              &lt;dd&gt;is taken from the dependency element&lt;/dd&gt;
              
              &lt;dt&gt;artifactId&lt;/dt&gt;
              &lt;dd&gt;is taken from the dependency element&lt;/dd&gt;
