ant警告 “warning: 'includeantruntime' was not set”解决方法

将

<target name="compile" depends="init">
    <javac srcdir="${src}" destdir="${dest}" />
</target>

修改为

<target name="compile" depends="init">
    <javac srcdir="${src}" destdir="${dest}" includeantruntime="on" />
</target>

也就是添加 includeantruntime="on" 。
