Maven hangs forever when uploading a SECOND package with SAME artifactId

Question

Maven all of a sudden hangs forever at release:perform when trying to upload a file:

15:30:30 Build was aborted

I then added -X to maven command and then I found it hangs at this command:

 /usr/local/jdk1.6.0_45/jre/bin/java -Dclassworlds.conf=/usr/local/apache-maven-2.2.1/bin/m2.conf -Dmaven.home=/usr/local/apache-maven-2.2.1 -classpath /usr/local/apache-maven-2.2.1/boot/classworlds-1.1.jar org.codehaus.classworlds.Launcher -Durl=http://mavenrepo:8081/nexus/content/repositories/idc-releases -DrepositoryId=mvnp01.repo.com deploy:deploy-file -DuniqueVersion=false -DgroupId=com.mycompany.impaxdatacenter -Dversion=3.1.1.0.0-77_testing_ken2 -DartifactId=$1 -DgeneratePOM=false -Dfile=..//$2 -Dpackaging=$3 -B -X

This is also equivalent to this maven deploy:deploy-file command:

 mvn -X deploy:deploy-file  org.codehaus.classworlds.Launcher -Durl=http://mavenrepo:8081/nexus/content/repositories/idc-releases -DrepositoryId=mvnp01.repo.com deploy:deploy-file -DuniqueVersion=false -DgroupId=com.mycompany.impaxdatacenter -Dversion=3.1.1.0.0-77_testing_ken2 -DartifactId=$1 -DgeneratePOM=false -Dfile=$2 -Dpackaging=$3 -B

artifactId - $1
path to file - $2
package type - $3

I played around with this command and found that maven hangs forever when uploading a SECOND package with SAME artifactId.

Is this a bug in maven-deploy-plugin:2.4 ??
