Can not perform a release with clearcase as a scm

[邓 <ne...@163.com>]

Hi
   I have some troubles when working with maven and clearcase.
   In order to release a project, I type 'mvn release:prepare --batch-mode' and the commond success.but when I type 'mvn release:perform' a BUILD ERROR occurs,I'm using maven in SunOS and in my project's pom I have the following configure
 <scm>
       <connection>scm:clearcase:load /bmf_core/src/bmf-core</connection>
 </scm>
   <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-release-plugin</artifactId>
        <configuration>
          <workingDirectory>/tmp/release_build_working</workingDirectory>
        </configuration>
      </plugin>
    </plugins>
  </build>
