@*Sean* & @Manuel, Thanks for your replies.
I solved this problem by adding a lower version of mahout-examples to
dependencies of mahout-integration, since maven is identify a unique
project by its groupId, artifactId and version, so we can avoid Maven
Circular Dependency by specify a different version of A to dependency of B
since B is dependency of A.
For example, Now i am run mahout 0.9-SNAPSHOT, there already has a
dependency in *mahout-examples/pom.xml* like this:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mahout-integration</artifactId>
</dependency>
The version of this dependency is 0.9-SNAPSHOT implicitly. So, if i just
add below code into *mahout-integration/pom.xml*:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mahout-examples</artifactId>
</dependency>
The Maven Circular Dependency problem will arise. But if we specify a
different version of mahout-examples as mahout-integration's
dependency(lower that 0.9, for example, 0.8), that will be fine:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mahout-examples</artifactId>
<version>0.8</version>
</dependency>
Regards.
