Maven 突然在release:perform尝试上传文件时永远挂起：

然后我将 -X 添加到 maven 命令，然后我发现它挂在这个命令上：
/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
这也相当于这个 maven deploy:deploy-file 命令：
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
文件路径- $2
包类型- $3
我玩弄了这个命令，发现在上传带有SAME artifactId的SECOND包时，maven 永远挂起。
这是 maven-deploy-plugin:2.4 中的错误吗？
