Question

I have a web-app with following dependencies in pom:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.11</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derby</artifactId>
    <version>10.9.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>4.1.9.Final</version>
    <scope>test</scope>
</dependency>

With this configuration, I get following error in junit test:

java.lang.ClassFormatError: Absent Code attribute in method that is
not native or abstract in class file javax/persistence/Persistence

I found some info on this error here.
So, I removed ‘javaee-web-api’ dependency.

After that I get compilation error ‘package javax.persistence does not exist’, and many more.

So, I changed scope of ‘hibernate-entitymanager’ to default (compile).

The working pom (dependencies) look like this:

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.11</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derby</artifactId>
    <version>10.9.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>4.1.9.Final</version>
</dependency>

Now everything is OK, except generated war contains hibernate jar, which I do not want.

Any suggestion how to fix this, correct maven pom?

If you are working with an in application server, you can replace the hibernate dependency with a (still vendor specific) JPA API with provided scope like this ( example is for JBoss with hibernate):

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <scope>provided</scope>
</dependency>
