maven-ant-tasks doesn't resolve the latest artifact version from the local repository

Question

probably it will sound like silly question but I'm stuck. I have ant build.xml which has maven-ant-tasks

<target name="downloadDependencies">
    <artifact:dependencies filesetId="dependency.fileset" useScope="runtime">
        <dependency groupId="<my_artifact_group_id>" artifactId="<my_artifact_id>" version="latest"/>
    </artifact:dependencies>

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

    <copy todir="${build.dir}/lib">
        <fileset refid="dependency.fileset" />
        <mapper type="flatten" />
    </copy>
</target>

I need to provide the latest version because it's my own artifact, seems like the ant maven task doesn't know to resolve it. The error I get

BUILD FAILED .../build.xml:20: Unable to resolve artifact: Missing: ---------- Try downloading the file manually from the project website.

Then, install it using the command: mvn install:install-file -DgroupId= -DartifactId= -Dversion=latest -Dpackaging=jar -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId= -DartifactId= -Dversion=latest -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

Question: How can I force the ant maven plugin to resolve the latest version?

"The error I get" and then it's cut off... What error are you getting exactly? Please edit that into your question. — TT., Jan 20 '16 at 20:39

I think your issue is with how you have published the version

mvn install:install-file .... -Dversion=latest ...

To the best of my knowledge Maven doesn't have any special handling or a "latest" string. You must explicitly set a valid version number when installing the artifact. For example

mvn install:install-file .... -Dversion=1.1 ...

I thought that maven does support this feature This link explains this stuff pretty good http://stackoverflow.com/questions/30571/how-do-i-tell-maven-to-use-the-latest-version-of-a-dependency – Denis Voloshin Jan 20 '16 at 21:42
@Denis It doesn't. I have revised my answer to make that statement more explicit – Mark O'Connor Jan 20 '16 at 21:44
Thanks for reply, I got the error. I had to use RELEASE because the dependancy isn't snapshot. – Denis Voloshin Jan 20 '16 at 22:01
