Dependency conflict in maven subprojects

I have dependency problems. I have a maven project, with a number of subproject.

• com.mycompany.utility1
• com.mycompany.application1
• com.mycompany.application2

Application1 depends on Utility1 and works perfectly. For Application2 I have added the dependency for a new feature. Using it, gives me...

Exception in thread "main" java.lang.ExceptionInInitializerError
    ...
    at Foo.main(Foo.java:27)
Caused by: com.google.inject.CreationException: Unable to create injector, see the following errors:

  while locating com.google.api.ads.common.lib.soap.SoapClientHandlerInterface

When I move class Foo to the Application1 subproject, it does run as intended, but emits:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

All the logging and Guice stuff is in subproject Utility1 and both Application1 and Application2 have the same dependency in their pom files.

I have tried to read up on solving dependy issues and I have run mvn enforcer:enforce on the project. It shows:

[WARNING] Rule 0: org.apache.maven.plugins.enforcer.DependencyConvergence    failed with message:

What confuses me most is that the same code runs when part of Application1 but not Application2. What do I do?
