Question

我正在编译代码并生成我的桌面应用程序jar。但我无法调试代码。我想放置断点并使用Eclipse F6和F5函数逐步进行。有没有办法做到这一点？谢谢你的帮助？我的蚂蚁脚本如下：

<project name="R - 09 - tester">

<property name="app.name" value="Tester" />
<property name="app.version" value="2.0" />
<property name="dir.root" value="C:/.../trunk" />

<target name="run" description="Run the Application" depends="build">

</target>

Answer 1

您应该使用<java>标记启用远程调试。

<java ....>
 <jvmarg value="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5555"/>
</java>

现在运行你的ant脚本。它将启动java进程并等待，直到您将调试器连接到porr 5555。

如果您不想等到suspend=y更改为suspend=n。

Answer 2

antscript的最终状态如下：

<target name="compile">
    <javac  srcdir="src" destdir="${dir.class}/${app.name}" debug="true" debuglevel="lines,vars,source" >
        <classpath>
            <pathelement location="..." />
        </classpath>
    </javac>
</target>

<target name="debug" description="Debug the Application" depends="compile">
    <java jar="${dir.binary}/${app.name}-${app.version}.jar" fork="true">
        <jvmarg value="-Xdebug" />
        <jvmarg value="-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5555" />
    </java>
</target>
