During life of your project you can change the ivy.xml file or <a href="maven.html">maven pom.xml</a> and change the configuration you want to use. These properties can be accessed by contextual menu of the IvyDE class path container: <center><img src="../images/cp_configuration.jpg"></center> You can also edit it via the build path configuration. Open the build path configuration dialog, select the "Libraries" panel and select the IvyDE classpath container. Then you will be able to click on the button "Edit": the IvyDE classpath container configuration dialog will pop up. This is particularly useful when Eclipse hides the empty classpath containers (since Eclipse 3.3), and then this is only way to trigger a resolve. <br/><br/> <center><img src="../images/build_path_edit.jpg"></center> <br/>
