How to create maven build on bamboo ? Unable to create build by using profile as in pom.xml

[pp]

I have already configured job with maven command as "clean install -Psample"  (sample is my profile name in pom.xml as shown below) . But I started running the build it is giving issue as  " Non-readable POM /appl/bamboo-agent/xml-data/build-dir/project/pom.xml (No such file or directory)  The build could not read the project [Help 1]" 

1)  How to configure bamboo job to generate maven build ?

2) How to run build with "sample" profile as shown below ? Can you suggest step by step configuration ?

3) Can we run "clean install" only to generate bamboo build ? 

4) How to integrate third party dependencies in build plan if we require ?

My pom.xml with "sample " profile name ::

<profile>
    <id>sample</id>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <goals>
       <goal>exec</goal>
    </goals>
    <activation>
       <activeByDefault>true</activeByDefault>
    </activation>
</profile>
