Javed Mandary commented on HHH-5896:
------------------------------------

Having looked again at the issue it would seem that in some instances maven3 hides transitive dependencies it is bringing into your build .. to be sure where unwanted dependencies are comming from add the -X flag e.g mvn clean install -X .

I've found that hibernate-3.2.5.ga.jar was being added because I had a dependency with atomikos which was pulling out this jar transitively. Excluding the hibernate-3.2.5.ga jar from atomikos solved the problem:

<dependency>
<groupId>com.atomikos</groupId>
<artifactId>transactions-jta</artifactId>
<version>3.6.4</version>
<exclusions>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
</exclusion>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
</exclusion>
</exclusions>
</dependency>

> Hi,
>    I would seem that if you include the hibernate-entitymanager (3.6.1) dependency within your maven build and your using Maven 3 , this pulls the hibernate-3.2.5.ga.jar within your classpath somehow.
> Eventually what happens is that if you try to run your application within say tomcat and that bundles the hibernate-entitymanager jar as well as the hibernate-3.2.5.ga.jar you get the following exception:
> Invocation of init method failed; nested exception is java.lang.IncompatibleClassChangeError: Implementing class
> 	at org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.postProcessPropertyValues(CommonAnnotationBeanPostProcessor.java:300)
> Solution which I've found is to move down to maven 2 or to expliclty or manually remove the hibernate-3.2.5.ga.jar  from your build.
