Cobertura mag meine Hibernate Config nicht

Snyke · **Posted:** Thu Jul 03, 2008 7:00 pm

Also ich benutz momentan Maven 2 um mein Projekt zu bauen, meine Unit tests laufen wunderbar durch nur wenn ich die Cobertura tests durchlaufen lassen will findet Maven die Klassen die mit Hibernate gemappt werden nicht mehr:

Hi Snyke,

Quote:

org.hibernate.MappingException: Unable to load class declared as <mapping class="myproject.model.User"/> in the configuration:

Das mit dem Finden vom Mapping-Dateien scheint manchmal recht unintuitiv zu sein, so meine Erfahrung. Hab manchmal das Gefühl, dass das mit dem CLASSPATH nicht so ganz stimmt.

Lösungsversuch 1:
Eine Mapping Datei muss, glaub ich, die Endung .hbm.xml (in Deinem Falle also User.hbm.xml) haben. Das muss auch in dem XML-Tag mitsamt der Endung stehen.

Lösungsversuch 2:
Vom Ort deiner hibernate.cfg.xml gibst du mal den relativen Pfad (also mit "/" (forward slashes) anstatt "." (Punkten)) zur Mapping-Datei ein (also etwa <mapping class="myproject/model/User"/>). Das würde bedeuten, dass deine hibernate.cfg.xml im gleichen Verzeichnis wie myproject/ liegt.

Lösungsversuch 3:
<mapping class="classpath:User_Mapping_File"/>, da ja vermutlich die Datei innerhalb deines CLASSPATH liegt... (User_Mapping_File übrigens mit dem realen Dateinamen des Mapping-Files ersetzen)

CU

Naja das Problem is nicht dass es die mappings nicht findet sondern die Javaklassen mit den Annotations nicht findet.

I read the translated page. Question in English:
I am having the same problem. My tests run successfully without cobertura but fail when I run mvn cobertura:cobertura
Did anyone have a solution to this? I could not see it posted.
Thanks Jol.

Hi again, I actually solved my own problem by changing the hibernate-plugin configuration by this:

Code:

         <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>hibernate3-maven-plugin</artifactId>
            <version>2.1</version>
            <configuration>
               <components>
                  <component>
                     <name>hbm2ddl</name>
                     <implementation>annotationconfiguration</implementation>
                  </component>
               </components>
               <componentProperties>
                  <drop>false</drop>
                  <jdk5>true</jdk5>
                  <configurationfile>target/classes/hibernate.cfg.xml</configurationfile>
                  <skip>true</skip>
               </componentProperties>
            </configuration>
            <executions>
               <execution>
                  <phase>process-test-resources</phase>
                  <goals>
                     <goal>hbm2ddl</goal>
                  </goals>
               </execution>
            </executions>
            <dependencies>
               <dependency>
                  <groupId>${jdbc.groupId}</groupId>
                  <artifactId>${jdbc.artifactId}</artifactId>
                  <version>${jdbc.version}</version>
               </dependency>
            </dependencies>
         </plugin>

Notice the <skip>true</skip> part in the compontentProperties, actually I have no clue what that's for, but it solved the problem ^^

I just found this possible cause in
http://cobertura.sourceforge.net/faq.html

Cobertura uses ASM to modify your bytecode. There are a few other popular programs that use ASM; Groovy and *Hibernate*, to name two. You could have problems if Cobertura uses a different version of asm and you add both versions to your classpath.
