Мой код соответствует, но когда я пытаюсь запустить Enhancer DataNucleus, я не могу завершить этап компиляции сообщения. Я предполагаю, что мне не хватает файла jar, но какой? Я включил ошибку и pom.xmlDataNucleus enchancer не может создать экземпляр org.datanucleus.api.jdo.JDOAdapter
Я скопировать инструкции на страницах Google:
<plugin>
<groupId>org.datanucleus</groupId>
<artifactId>maven-datanucleus-plugin</artifactId>
<version>3.2.0-m1</version>
<configuration>
<api>JDO</api>
<props>${basedir}/datanucleus.properties</props>
<verbose>true</verbose>
<enhancerName>ASM</enhancerName>
</configuration>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-api-jdo</artifactId>
<version>3.1.3</version>
</dependency>
</dependencies>
</plugin>
И я получаю эту ошибку.
And I get this error.

Почему бы вам использовать datanucleus-core/datanucleus-json из v4.x с datanucleus-api-jdo v3.1.x и datanucleus Maven плагин v3.2.x ??! Совершенно непоследовательно. –
О, и нет такой вещи, как «javax.jdo» jdo-api v3.1.3. –
Какова ваша рекомендация по правильным версиям? Вот что GAE рекомендовал на их [link] (https://cloud.google.com/appengine/docs/java/datastore/jdo/overview-dn2#Copying_the_JARs) веб-сайте: ' org.datanucleus datanucleus- api-jdo 3.1.3 ' –
