running specific target in different ant scripts in different directories

Question

We have a large amount of apps. They all have a build.xml file located in the projects base directory. I am trying to create an ant script that will go through

Answer 1

Is it possible to run the target in the all the build files concurrently ?

E.g.

<project name="Dry run" default="run">
    <target name="run">
        <subant target="test">
            <filelist dir="projects" files="one/build.xml,two/build.xml,three/build.xml,four/build.xml"/>
        </subant>
    </target>
</project>

In this example, is there any way to run target "test" present in all the build files (one/build.xml,two/build.xml,three/build.xml,four/build.xml) concurrently ?

Answer 2

You specified the antfile attribute, so ANT was expecting to a single build.xml file.

The subant documentation describes how you can use a fileset as child parameter.

Here's an example:

<project name="Subant demo" default="run-debug-target">
    <target name="run-debug-target">
        <subant target="debug">
            <fileset dir="." includes="**/build.xml" excludes="build.xml"/>
        </subant>
    </target>
</project>

Update

Alternatively a filelist could be used:

<project name="Dry run" default="run">
    <target name="run">
        <subant target="test">
            <filelist dir="projects" files="one/build.xml,two/build.xml,three/build.xml,four/build.xml"/>
        </subant>
    </target>
</project>

Processing the following build files:

• projects/one/build.xml
• projects/two/build.xml
• projects/three/build.xml
• projects/four/build.xml
