Maven enhance goal gives java.lang.NoClassDefFoundError #25

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm trying to enhance a domain class which has an EntityListener with JPA 
Lifecycle Events.
These events use the AppEngine Search API to store documents in search index 
after persisting the entity.

When I run the enhance goal I get an exception that the Search API classes 
cannot be found. 
But off course I have a dependency to these classes in my pom.xml:

<dependency>
    <groupId>com.google.appengine</groupId>
    <artifactId>appengine-api-1.0-sdk</artifactId>
    <version>${com.google.appengine.version}</version> <!-- 1.7.7.1 -->
</dependency>

A normal mvn compile gives a successful build.

Below the result of enhance goal:

I wonder if there is something wrong with the classpath which is used by the

The DataNucleus classpath seems not to include all project dependencies.

Is the enhance goal setting the datanucleus classpath?

I think this is fixed in the 1.8.0 version of the plugin.
Can you try and let us know?

Similar problem here. I had to downgrade my maven plugin to 3.1.0-release 
before I got past the 

Exception in thread "main" java.lang.NoSuchMethodError: 
org.datanucleus.api.ApiAdapter.isMemberDefaultPersistent(Ljava/lang/Class;)Z

exception.

Could you share your pom.xml? That would help tremendously. No code needed...

Sure. My Pom is kindof a mess since I've been experimenting with different 
packages and so on, sorry. I hope it helps.

Any update on this as I'm experiencing this behaviour still on latest 1.8.5?

Do you need any more info from me to help you?

with these versions, I think its ok:   

 <dependency>
      <groupId>javax.jdo</groupId>
      <artifactId>jdo-api</artifactId>
      <version>3.0.1</version>
    </dependency>

    <dependency>
      <groupId>org.datanucleus</groupId>
      <artifactId>datanucleus-core</artifactId>
      <version>3.1.4</version>
    </dependency>  
    <dependency>
      <groupId>com.google.appengine.orm</groupId>
      <artifactId>datanucleus-appengine</artifactId>
      <version>2.1.2</version>
    </dependency>
    <dependency>
      <groupId>org.datanucleus</groupId>
      <artifactId>datanucleus-api-jdo</artifactId>
      <version>3.1.3</version>
    </dependency> 

not sure why newer versions have issues
