java – buildFinished和buildStarted将无法正常工作

public class ExtendedLogger extends DefaultLogger {
    // My stuff
}

我拿了信息here.

所以我从DefaultLogger重载了一些方法：

@Override
public void targetStarted(BuildEvent event){
    System.out.println("Logger : "+"[TARGET STARTED]n");
}

@Override
public void targetFinished(BuildEvent event){
    System.out.println("Logger : "+"[TARGET FINISHED]n");
}

哪个效果很好(我可以看到输出).

这些方法也有效：

public void taskStarted(BuildEvent event);
public void taskFinished(BuildEvent event);

但是我遇到了麻烦：

@Override
public void buildFinished(BuildEvent event) {
    System.out.println("Logger : "+"[BUILD FINISHED]n");
}

@Override
public void buildStarted(BuildEvent event) {
    System.out.println("Logger : "+"[BUILD STARTED]n");
}

不可能进入这些方法！

我哪里错了？

谢谢.

我刚尝试了一个像@Vaspar这样简单的testBuild.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project name="MyProject" default="Init" basedir=".">



<target name="Init">
    <!-- Create the time stamp -->
    <tstamp/>
    <!-- Create the build directory structure used by compile -->
    <echo message="INIT-ING"/>
</target>


<!-- targets used in my project -->
<target name="Clean" description="Clean output directory.">
    <echo>Clean</echo>
</target>

<target name="CleanAutogenerated" description="Clean auto-generated folder.">
    <echo>CleanAutogenerated</echo>
</target>

<target name="AutoGenerateTopics" description="Manual specific targets.">
    <echo>AutoGenerateTopics</echo>
</target>

<target name="BuildDocument" description="Build full documentation">
    <echo>BuildDocument</echo>
</target>



</project>

输出是：

Logger : [TARGET STARTED] org.apache.tools.ant.BuildEvent[source=Clean]
Logger : [TASK STARTED] org.apache.tools.ant.BuildEvent[source=org.apache.tools.ant.UnknownElement@12f33e1]

Logger : [TARGET FINISHED] org.apache.tools.ant.BuildEvent[source=BuildDocument]
DocumentTask DONE

请注意,CleanDocumentTask DONE,DocumentTask DONE等等是我项目中的纯Java输出(不是ant).

如您所见,targetStarted或targetFinished仍然没有输出：/
