使用Ant构建当前构建目标的依赖关系

Question

假设我有一个库和二进制目标，我们称之为MyLib和MyBin，MyBin依赖于MyLib。

我正在尝试为MyBin创建一个Ant构建文件，它首先构建MyLib，然后在构建MyBin时将其包含在类路径中。

我在Building other, dependent projects with Ant尝试过使用Ant任务。

然而，它不起作用，从ant -v我认为MyBin build-deps目标甚至没有建立MyLib。好像它混淆了MyBin和MyLib属性？我不知道如何防止这种情况。

我只倾倒下面的MyBin/build.xml，但是MyLib几乎是相同的，除了它没有build-deps目标。

<project name="MyBin" default="main" basedir=".">
    <property name="projectName" value="MyBin" />
    <property name="src.dir" location="src" />
    <property name="build.dir" location="bin" />
    <property name="dist.dir" location="dist" />
    <property name="dist.lib.dir" location="dist/lib" />
    <property name="lib.dir" value="lib" />


<target name="build-deps" depends="init">
<!-- MyLib main target does clean -> build -> jar to dist folder -->
<!-- Its build.xml uses many of the same property values as above -->
        <ant antfile="../MyLib/build.xml" target="main"/>
</target>

<path id="classpath">
    <fileset dir="${basedir}/">
        <include name="../MyLib/dist/**/*.jar" />
    </fileset>
</path>

<!-- Need classpath to run this -->
<target name="compile" depends="build-deps" description="compile the source ">
    <javac includeantruntime="false" srcdir="${src.dir}"
                   destdir="${build.dir}" classpathref="classpath" />
</target>

<!-- Group all dependencies into a big dependency-all.jar -->
<target name="copy-dependencies">

    <mkdir dir="${dist.lib.dir}" />

    <jar jarfile="${dist.lib.dir}/dependencies-all.jar">
        <zipgroupfileset dir="${lib.dir}">
            <include name="**/*.jar" />
        </zipgroupfileset>
    </jar>

</target>

<!-- jar it, extract above dependency-all.jar and zip it with project files -->
<target name="jar" depends="compile, copy-dependencies"
            description="package, output to JAR">

    <mkdir dir="${dist.dir}" />
    <mkdir dir="${dist.lib.dir}" />

    <jar jarfile="${dist.dir}/${projectName}.jar" basedir="${build.dir}">
        <manifest>
            <attribute name="Main-Class" value="${main-class}" />
        </manifest>
        <zipfileset src="${dist.lib.dir}/dependencies-all.jar"
                            excludes="META-INF/*.SF" />
    </jar>

</target>

<target name="clean" description="clean up">
    <delete dir="${build.dir}" />
    <delete dir="${dist.dir}" />
</target>

<!-- Default, run this -->
<target name="main" depends="clean, compile, jar" />
</project>

我在ant -v in MyBin看到的是：

build-deps:
Project base dir set to: /MyBin
      [ant] calling target(s) [main] in build file /MyLib/build.xml
