| <h1>Modifying the Ant classpath</h1> |
| <p>When using an optional or custom task it is usually necessary to add extra libraries to the classpath. The Ant |
| classpath can be modified globally or per launch configuration.</p> |
| <p>To modify the Ant classpath globally:</p> |
| <ol> |
| <li>Open the <a class="command-link" href= |
| 'javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.ant.ui.AntRuntimePreferencePage)")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="command link"> <b>Ant > Runtime</b></a> |
| preference page.</li> |
| <li>If you are not on it already, click the <b>Classpath</b> tab.<br> |
| <br> |
| <img src="../images/ant_runtime_classpath.png" alt="Ant runtime classpath global preferences" border="0"></li> |
| <li>To add a JAR file to the classpath, click <b>Add Jar</b> and select the JAR file.</li> |
| <li>To add a folder to the classpath, click <b>Add Folder</b> and select the folder.</li> |
| <li>To remove an item from the classpath, select it and click <b>Remove</b>.</li> |
| <li>To restore the classpath to the default, click <b>Restore Defaults</b>.</li> |
| </ol> |
| <p>To modify the Ant classpath for a launch configuration:</p> |
| <ol> |
| <li>Click <a class="command-link" href= |
| 'javascript:executeCommand("org.eclipse.ui.externalTools.commands.OpenExternalToolsConfigurations")'><img src= |
| "PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="command link"> <b>Run > External Tools > External |
| Tools...</b></a>.</li> |
| <li>Select the Ant configuration whose classpath you wish to modify</li> |
| <li>Select the <b>Classpath</b> tab<br> |
| <br> |
| <img src="../images/ant_classpath_tab.png" alt="Ant launch configuration classpath tab" border="0"></li> |
| <li>To add a JAR file to the classpath, click <b>Add Jar</b> and select the JAR file.</li> |
| <li>To add a folder to the classpath, click <b>Add Folder</b> and select the folder.</li> |
| <li>To remove an item from the classpath, select it and click <b>Remove</b>.</li> |
