在我的插件調用Ant任務和輸出重定向到控制檯

在我的Eclipse插件，我試圖執行一個Ant任務，並輸出到Eclipse控制檯這裏重定向是我的代碼：在我的插件調用Ant任務和輸出重定向到控制檯

AntRunner runner = new AntRunner(); 
    runner.addBuildLogger("myplugin.AntLogger");   

    String projectPath = getProject().getLocation().toString(); 
    String buildFileLocation = projectPath + File.separator + "build.xml"; 
    runner.setBuildFileLocation(buildFileLocation); 
    runner.setExecutionTargets(new String[] { "build-for-device" });

的AntLogger代碼是：

public class AntLogger extends org.apache.tools.ant.DefaultLogger { 

private IOConsole console = new IOConsole("Ant", null); 
private IOConsoleOutputStream outputStream = console.newOutputStream(); 

public AntLogger() { 
    ConsolePlugin.getDefault().getConsoleManager() 
      .addConsoles(new IConsole[] { console }); 
} 

@Override 
protected void printMessage(String message, PrintStream stream, int priority) { 
    super.printMessage(message, stream, priority); 
    try { 
     outputStream.write(message + "\n"); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
}

}

和我增加了的ant.jar到plugin.xml

<extension 
    point="org.eclipse.ant.core.extraClasspathEntries"> 
    <extraClasspathEntry 
     library="ant.jar"> 
    </extraClasspathEntry> 
</extension>

不管我做什麼，我不斷收到類未發現異常：

你在classpath有ant.jar文件？ – oers 2012-03-01 10:47:04

是的，它是在擴展點中添加的，我一遍又一遍地檢查了它。 – Chen 2012-03-01 12:41:23

也許在運行時無法找到它？或者ant.jar不包含那個類？ – oers 2012-03-01 14:38:26

在這個撞我的頭後，我終於找到了解決辦法：

的AntLogger類不能插件項目的一部分。我感動AntLogger給它命名爲EclipseAntLogger不同的Java項目，然後我加入這個項目罐子的插件擴展點是這樣的：

<extension 
    point="org.eclipse.ant.core.extraClasspathEntries"> 
    <extraClasspathEntry 
     library="lib/EclipseAntLogger.jar"> 
    </extraClasspathEntry> 
</extension>

它是否有助於增加ant.jar和其他必要的罐子到AntRunner實例？

public void setCustomClasspath(URL[] customClasspath)

謝謝，但這不起作用。 – Chen 2012-03-06 12:42:44
