构建已完成和构建已开始将不起作用

Question

我从DefaultLogger到org.apache.tools.ant.DefaultLogger:创建了一个子类

public class ExtendedLogger extends DefaultLogger {
    // My stuff
}

我在这里获取了信息。

所以我重载了DefaultLogger:中的一些方法

@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");
}

效果很好（我可以看到输出）。

这些方法也起作用：

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

但我有问题与：

@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");
}

用这些方法是不可能的！

我哪里错了？

谢谢。

我刚刚尝试了一个简单的testBuild.xml，比如@Vaspar说：

<?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>

输出为：

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]

     [echo] AutoGenerateTopics

     [echo] BuildDocument

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

请注意，CleanDocumentTask DONE、DocumentTask DONE等…都是来自我的项目（而非ant）的纯Java输出。

正如您所看到的，targetStarted或targetFinished:/仍然没有输出

令人惊讶。我使用了你的代码示例，我也可以获得buildStarted/buildFinished日志。

自定义记录器

import org.apache.tools.ant.BuildEvent;
import org.apache.tools.ant.DefaultLogger;
public class CustomLogger extends DefaultLogger{
    @Override
    public void targetStarted(BuildEvent event){
        System.out.println("Logger : "+"[TARGET STARTED] " + event);
    }
    @Override
    public void targetFinished(BuildEvent event){
        System.out.println("Logger : "+"[TARGET FINISHED] " + event);
    }
    @Override
    public void taskStarted(BuildEvent event) {
        System.out.println("Logger : "+"[TASK FINISHED] " + event);
    }
    @Override
    public void taskFinished(BuildEvent event) {
        System.out.println("Logger : "+"[TASK FINISHED] " + event);
    }
    @Override
    public void buildFinished(BuildEvent event) {
        System.out.println("Logger : "+"[BUILD FINISHED] " + event);
    }
    @Override
    public void buildStarted(BuildEvent event) {
        System.out.println("Logger : "+"[BUILD STARTED] " + event);
    }
}

build.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>
</project>

下面是输出。

输出
