Objet : Cyclic dependency problem
Hi all.
I have just joined the list, so please forgive me if the exact same question
has already been posted.
Here is my use case :
I have a project CORE_A which exposes a facade in the form of an EJB, which is
built in a separate project EJB_A.
I have a project CORE_B which exposes a facade in the form of an EJB, which is
built in a separate project EJB_B.
CORE_A needs to call remote EJB_B, so it has a dependency on the client jar of
EJB_B.
CORE_B needs to call remote EJB_A, so it has a dependency on the client jar of
EJB_A.
EJB_A depends on CORE_A for its build.
EJB_B depends on CORE_B for its build.
In my CORE_A and CORE_B POM files, I have tried to avoid getting a cyclic
dependency error in the build phase
by :
- using a client classifier for the depency of CORE to EJB client
- using an exclusion
e.g. for the pom.xml of the CORE_A project :
<dependency>
<groupId>com.acme</groupId>
<artifactId>EJB-B</artifactId>
<version>${applicationVersion}</version>
<classifier>client</classifier>
<exclusions>
<exclusion>
<groupId>com.acme</groupId>
<artifactId>CORE-B</artifactId>
</exclusion>
</exclusions>
</dependency>
But when I launch the install goal, I immediately get a cyclic dependency error
message, which seems to indicate that Maven
is ignoring my <classifier> or <exclusion> modifiers, and basing its graph
calculation solely on the list of depencies.
I use Maven 2.0.7.
Has anyone got a solution ?
