Building other, dependent projects with Ant

Question

Let me preface by saying that I am new to Ant. As in, I just started learning it 2 days ago in order to accomplish this task.

What I\'m trying to do is create a \"m

Here are some general guidelines (not rules, Ant is quite liberal):

• a build.xml is generally designed to be run on a specific project, so it is not 'imported' in other builds
• the import task is generally used to share some comme piece of build mechanic, not a piece of build workflow like you are doing. For instance a target to build jar, parameterized by some properties like the target directory.
• the subant and ant tasks are preferred used to trigger builds of other project

So here is what would look like a build.xml for project D:

<project name="CommonJava" default="makeCommonJavaJar" basedir=".">

    <target name="build-deps">
        <ant antfile="../Common/build.xml" target="makeCommonJar"/>
        <ant antfile="../CommonAndroid/build.xml" target="makeAndroidJar"/>
    </target>

    <target name="makeCommonJavaJar" depends="build-deps">
        <mkdir dir="build" />
        <jar jarfile="./build/commonjava.jar" includes="*.class" />
    </target>

</project>
