Datanucleus + GWT Процесс компиляции

Question

Я пытаюсь скомпилировать проект GWT + App Engine + JDO + Datanucleus с Maven. Когда maven начинает компилировать исходники Java, я получаю сообщение об ошибке:

    [DEBUG] Source roots:
[DEBUG]  /home/desarrollo26/eclipse-workspace/projectName/src
[DEBUG]  /home/desarrollo26/eclipse-workspace/projectName/target/generated-sources/annotations
[DEBUG] Command line options:
[DEBUG] -d /home/desarrollo26/eclipse-workspace/projectName/target/projectName-1.0-SNAPSHOT/WEB-INF/classes -classpath (all .m2 dependencies)
[DEBUG] incrementalBuildHelper#beforeRebuildExecution

DataNucleus : JDOQLTypedQuery Q class generation : com.projectName.server.extension.TokenExtension -> com.projectName.server.extension.QTokenExtension

Я следовал за всеми процессами datanucleus-maven, JDO и Enhanced со страницы документации Datanucleus, а JDO и JDO Query присутствуют в CLASSPATH, но постоянная ошибка:

На самом деле, мои зависимости для JDO / JPA, Datanucleus:

Кто-нибудь знает, что может вызвать эту ошибку? Спасибо!
