maven deploy does not work for versions

Hi I am a beginner for maven build tool. I built a simple maven JavaEE project and I tried to build it remote nexus repository. But i can deploy successfully only for snapshots. Releases deploying gives 400 bad request error.

here is my Setting.xml configuration

     <servers>
            <server>
                    <id>****</id>
                    <username>****</username>
                    <password>****</password>
            </server>
    </servers>

    <mirrors>
        <mirror>
                <id>nexus</id>
                <mirrorOf>central</mirrorOf>
                <url>http://******:8081/nexus/content/groups/net.******.timetrack/</url>
        </mirror>
    </mirrors>

<profiles>
    <profile>
            <id>nexus</id>
            <repositories>
                <repository>
                    <id>*****</id>
                    <url>http://******:8081/nexus/content/groups/net.*******.timetrack/</url>
                    <releases><enabled>true</enabled></releases>
                    <snapshots><enabled>true</enabled></snapshots>
                </repository>
            </repositories>

            <pluginRepositories>
                <pluginRepository>
                    <id>******</id>
                    <url>http://******:8081/nexus/content/groups/net.******.timetrack/</url>
                    <releases><enabled>true</enabled></releases>
                    <snapshots><enabled>true</enabled></snapshots>
                </pluginRepository>
            </pluginRepositories>
        </profile>
</profiles>

<activeProfiles>
            <activeProfile>nexus</activeProfile>
</activeProfiles>

and here is my pom.xml's distribution management

<distributionManagement>
        <repository>
            <uniqueVersion>false</uniqueVersion>
            <id>*****</id>
            <name>******</name>
            <url>http://*******:8081/nexus/content/groups/net.******.timetrack/</url>
            <layout>default</layout>
        </repository>
        <snapshotRepository>
            <uniqueVersion>true</uniqueVersion>
            <id>*****</id>
            <name>***** Snapshots</name>
            <url>http://******:8081/nexus/content/repositories/snapshots/</url>
            <layout>legacy</layout>
        </snapshotRepository>
    </distributionManagement>

If I run mvn clean deploy with (for a snapshot)

<groupId>net.*****.*****</groupId>
<artifactId>*****-**-****</artifactId>
<version>1.4-SNAPSHOT</version>
<packaging>war</packaging>

then successfully deploy in to nexus repository snapshot directory.

If it I run mvn clean deploy with (for a release)

<groupId>net.*****.****</groupId>
<artifactId>****-***-*****</artifactId>
<version>1.4.1</version>
<packaging>war</packaging>

then it gives 400-bad request error

Here is the log for the error

Thanks.

You can deploy a release version of a given artifact exactly once to a given Nexus instance.

If the same version already exists in your Nexus, you'll get an error like the one you're seeing.
