artifact:deploy - The name of deploying element in snapshot repository is wrong

The zip file contains test with Ant.
To launch it : ant test.
I try to deploy a snapshot artifact in repository
So, my pom.xml contains a version with the extension '-SNAPSHOT'
And in my build file Ant i do this :
<artifact:deploy file="lib/$

{pom.artifactId}.jar">
<remoteRepository url="file:./repository" />
<pom refid="pom" />
</artifact:deploy>

In the repository the name of the artifact is <artifactId><version>SNAPSHOT.<packaging> instead of <artifactId><version><date>.<time><buildNumber><packaging>


Another problem, i try to upload 2 attachments with my artifact (javadoc and java-source), and the buildNumber in the meta-data.xml increment by 3 instead of 1
<artifact:deploy file="lib/${pom.artifactId}

.jar">
<remoteRepository url="file:./repository" />
<pom refid="pom" />
<attach file="./lib/$

{pom.artifactId}-src.jar" type="java-source"/>
<attach file="./lib/${pom.artifactId}

-api.zip" type="javadoc"/>
</artifact:deploy>
You can test it with : ant testWithAttach
