  • 0

Assuming that the two are compatible, how can I force Maven 2 to use Ehcache 2.2.0 instead of Ehcache 1.2.3 with Hibernate 3.3.2.GA?

Essentially, I wish to replace the puzzling and practically cyclic dependency chain

with

Update:

I learned that hibernate-commons-annotations-3.3.0.ga also depends on artifact ehcache-1.2.3:

[INFO] +- org.hibernate:hibernate-commons-annotations:jar:3.3.0.ga:compile
[INFO] |  +- org.hibernate:hibernate:jar:3.2.1.ga:compile
[INFO] |  |  +- net.sf.ehcache:ehcache:jar:1.2.3:compile
[INFO] |  |  +- asm:asm-attrs:jar:1.5.3:compile
[INFO] |  |  +- cglib:cglib:jar:2.1_3:compile
[INFO] |  |  \- asm:asm:jar:1.5.3:compile
[INFO] |  \- javax.persistence:persistence-api:jar:1.0:compile

What is the purpose of hibernate-commons-annotations-3.3.0.ga? Does Hibernate need this artifact if it uses hibernate-annotations-3.2.1-ga? Is there a replacement for this artifact that doesn’t include Ehcache? Should I simply try to exclude it from the build?

    Assuming that the two are compatible, how can I force Maven 2 to use Hibernate 3.3.2.GA with Ehcache 2.2.0? According to their respective Maven POM files:

    I’ve investigated this question for my personal needs and I have now concrete answers. All the required informations are available online and I’m just posting a very short version of howto use Ehcache 2.x with Hibernate 3.3+.

    First, you need to declare the dependency on the ehcache artifact.

    <dependency>
  <groupId>net.sf.ehcache</groupId>
  <artifactId>ehcache</artifactId>
  <version>2.2.0</version>
  <type>pom</type>
</dependency>

    Then, configure Hibernate for second level caching and specify the second level cache provider:

    <property key="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>

    Important things to note:

    • we are using the property for the new Hibernate 3.3/3.5 SPI (that Ehcache 2.0+ supports)
      • hibernate.cache.region.factory_class
    • we are using the cache provider provided by Echache
      • net.sf.ehcache.hibernate.EhCacheRegionFactory (and not o.h.c.EhCacheProvider)

    So you actually just don’t need the hibernate-ehcache artifact – and this solves the entire question 🙂 Here are the exact (relevant) dependencies I use:

    <dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-entitymanager</artifactId>
  <version>3.4.0.GA</version>
</dependency>
<dependency>
  <groupId>net.sf.ehcache</groupId>
  <artifactId>ehcache</artifactId>
  <version>2.2.0</version>
  <type>pom</type>
</dependency>

    And the tree:

    [INFO] +- org.hibernate:hibernate-entitymanager:jar:3.4.0.GA:compile
[INFO] |  +- org.hibernate:ejb3-persistence:jar:1.0.2.GA:compile
[INFO] |  +- org.hibernate:hibernate-commons-annotations:jar:3.1.0.GA:compile
