title: How to specify a maven repository
body: <p>I am taking over a project left by previous colleague. The project is mavenized and I'm having a hard time building it. There is a  inside  block, which generates error when I ran mvn install. The error shows that plugin cannot be found in maven central repo. I checked and it's not there. I happened to find another internal repository that has the plugin jar file. So outside the  block, I specified a  to point at that internal repo. However, when I ran mvn install again, it still goes to maven central repo to look for the plugin. How do I make it look for the jar file at the right repo? I thought by specifying the  list, it would automatically check that list? Other than the repo I added, there was no repository list set up previously.</p>
  
  <p>The missing plugin that I can't get it to work is like this:</p>
  
  <pre><code>    &lt;build&gt;
          &lt;plugins&gt;
              &lt;plugin&gt;
              &lt;groupId&gt;com.totsp.gwt&lt;/groupId&gt;
              &lt;artifactId&gt;maven-googlewebtoolkit2-plugin&lt;/artifactId&gt;
             &lt;version&gt;2.0-SNAPSHOT&lt;/version&gt;
              &lt;configuration&gt;
                  &lt;gwtVersion&gt;2.0.0&lt;/gwtVersion&gt;
                  &lt;style&gt;OBF&lt;/style&gt;
                  &lt;gen&gt;target/gwtgen&lt;/gen&gt;
                  &lt;runTarget&gt;/&lt;/runTarget&gt;
                  &lt;extraJvmArgs&gt;-Xmx512m&lt;/extraJvmArgs&gt;
                  &lt;port&gt;8088&lt;/port&gt;
                  &lt;useHtmlUnit&gt;true&lt;/useHtmlUnit&gt;
                  &lt;htmlUnitBrowsers&gt;
                      &lt;param&gt;FF3&lt;/param&gt;
                  &lt;/htmlUnitBrowsers&gt;
              &lt;/configuration&gt;
              &lt;executions&gt;
                  &lt;execution&gt;
                      &lt;goals&gt;
                          &lt;goal&gt;test&lt;/goal&gt;
                      &lt;/goals&gt;
                  &lt;/execution&gt;
              &lt;/executions&gt;
          &lt;/plugin&gt;
          &lt;/plugin&gt;
      &lt;/build&gt;
