是否有可能调试外部Ant任务？ [英] Is it possible to debug an external ant task?

问题描述

我有一个调用外部Ant任务的Ant脚本：

I have an ant script which calls an external ant task:

    <taskdef name="runStoriesAsEmbeddables" classname="org.jbehave.ant.RunStoriesAsEmbeddables"         
    classpathref="project.classpath" />

     <runStoriesAsEmbeddables includes="**/Ant*Stories.java" ignoreFailureInStories="true" 
     ignoreFailureInView="false" 
     systemProperties="story.path=.,qr.host=*,qr.port=*" generateViewAfterStories="true" />

和我想用-Xdebug启动JVM上的Unix机器。
在Java的任务Xdebug的，但对外部的任务......我不知道如何使用它 - 我读了几文档使用其jvmarg值=。
谢谢！

And I want to use -Xdebug to launch JVM on an unix box. I read several doc which using "jvmarg value="-Xdebug"" in "java" task but for external task...I don't know how to use it. Thanks!

推荐答案

设置ANT_OPTS环境变量。假设你使用的Bash shell：

Set the ANT_OPTS environment variable before running Ant. Assuming you use the Bash shell:

对于Java 1.4：

For Java 1.4:

export ANT_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=y

对于Java 1.5和更高版本：

For Java 1.5 and later:

export ANT_OPTS=-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=y

运行Ant脚本，然后连接到端口5005与调试器。

Run your Ant script and then attach to port 5005 with your debugger.
