Java 蚂蚁清理，如果不是最新的

在ANT中，我有一个包含以下目标的构建文件：

INIT您的示例非常接近-您可能需要调整映射器并注意绝对路径与相对路径。也许：

<uptodate property="tests.unnecessary">
    <srcfiles dir="src" includes="**/*.java"/>
    <mapper type="glob" from="*.java" to="../${build.dir}/classes/*.class"/>
</uptodate>

非常感谢。这就是我一直在寻找的D
<uptodate property="tests.unnecessary">
    <srcfiles dir="src" includes="**/*.java"/>
    <mapper type="glob" from="*.java" to="../${build.dir}/classes/*.class"/>
</uptodate>

<target name="check" depends="init">
    <uptodate property="tests.unnecessary">
        <srcfiles dir="src" includes="**/*.java"/>
        <mapper type="glob" from="*.java" to="${build.dir}/classes/*.class"/>
    </uptodate>
</target>

<target name="init">
    <echo message="Running init" />
</target>

<target name="clean" depends="check" unless="tests.unnecessary">
    <echo message="Running clean" />
</target>

<target name="compile" depends="clean" unless="tests.unnecessary">
    <echo message="Running compile" />
</target>

<target name="test" depends="compile" unless="tests.unnecessary">
    <echo message="Running test" />
</target>
