This might be the cause for the cyclic reference. Your parent pom
contains a dependency on and has a module defined as 'agentcommon'
...
<dependency>
<groupId>com.sinosafe.pcies</groupId>
<artifactId>agentcommon</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
<modules>
<module>agentcommon</module>
<module>agentwar</module>
<module>agentapp</module>
</modules>
...

HI,
Guys!I have set up a parent project which has three sub project.(see
the attachments please).Both the agentapp project
and the agentwar project is dependence agentcommon project. I have
installed the agentcommon project to the local repo.
and run mvn -N install under the parent project agent directory.so I
can package the other subproject agentapp and agentwar,
But when I package the agentcommon again,maven has reported the error
message like this:
