| <h1 class="topictitle1">Working with Ant</h1> |
| <div><div class="section"> <p>Ant support is provided as a built-in feature of the workbench. |
| If you right-click any XML file and select <span class="uicontrol">Run Ant</span> from |
| the pop-up menu, the Execute Ant Script dialog shows the available Ant targets. |
| You can check, in sequence, which ones are to be executed, and the execution |
| sequence will be shown beside each target. You can also select <span class="uicontrol">Display |
| execution log to Ant console</span>, which will cause any Ant messages |
| to be displayed in the Ant Console view (<span class="uicontrol">Perspective</span><span class="uicontrol">Show |
| View</span><span class="uicontrol">Other</span><span class="uicontrol">Ant</span><span class="uicontrol">Ant |
| Console</span>).</p> |
| <p>In addition, an Arguments field lets you pass |
| arguments, such as <samp class="codeph">-verbose</samp>, to the Ant program. If the Ant |
| script invokes the Ant <samp class="codeph">javac</samp> task, then a special <samp class="codeph">-Dbuild.compiler=org.eclipse.pde.internal.core.JDTCompilerAdapter</samp> argument must be passed or you will get a <samp class="codeph">Cannot use classic compiler</samp> error. </p> |
| <p>If |
| you use the the <samp class="codeph">deprecation="on"</samp> option for the <samp class="codeph">javac</samp> Ant |
| task, WebSphere<sup>®</sup> Studio |
| will crash. You should either specify nothing or use <tt>deprecation="off"</tt>.</p> |
| </div> |
| <ol><li class="stepexpand"><span>Create the following <samp class="codeph">echo.xml</samp> file inside any |
| project in your workspace:</span> <pre><?xml version="1.0"?> |
| <project name="Echo" default="echo" basedir="."> |
| <target name="echo"> |
| <echo message="HELLO from echo"/> |
| </target> |
| <target name="dir"> |
| <echo message="dir of ${basedir}:"/> |
| <exec dir="${basedir}" executable="cmd.exe"> |
| <arg line="/c dir"/> |
| </exec> |
| </target> |
| </project></pre> |
| </li> |
| <li class="stepexpand"><span>Right-click <samp class="codeph">echo.xml</samp> and select <span class="uicontrol">Run |
| Ant</span>.</span></li> |
| <li class="stepexpand"><span>The Run Ant dialog shows that you have two targets, echo and dir, |
| and that echo[1] is the default target that will be executed. If you also |
| select dir, it will change to dir[2] and it will be run as the second target. |
| Ensure that <span class="uicontrol">Display execution log to Ant console</span> is |
| checked and click <span class="uicontrol">Finish</span>. The script will then be run.</span> The results are displayed in the Ant Console.</li> |
| <li class="stepexpand"><span>Right-click <samp class="codeph">echo.xml</samp> and select <span class="uicontrol">Run |
| Ant</span> to run it again. This time enter <tt>-verbose</tt> in the |
| arguments entry field, then click <span class="uicontrol">Finish</span>.</span></li> |
| </ol> |
| <div class="example">Try editing your <samp class="codeph">echo.xml</samp> file to include the following <samp class="codeph">bad</samp> target |
| with a nonexistent task <samp class="codeph">propertyBad</samp>:<pre><target name="bad"> |
| <propertyBAD name="MyName" value="MyValue"/> |
| </target></pre> |
| <p>Right-click <samp class="codeph">echo.xml</samp> and select <span class="uicontrol">Run |
| Ant</span> to run it again. Select <span class="uicontrol">bad</span> as your |
| target and click <span class="uicontrol">Finish</span>. You will receive the following |
| error message, listed twice: "Could not create task of type: <samp class="codeph">propertyBad</samp>" |
| in the Problems view. You can partly fix this by changing <samp class="codeph">propertyBad</samp> to |
| property, and then saving <samp class="codeph">echo.xml</samp>. The errors in the Task |
| view will remain, because the errors are Ant runtime errors. If you run Ant |
| again, the error messages will disappear.</p> |
