Java InvocationTargetException:Plugin（Bundle）"；org.datanucleus“；已注册

我正在尝试跟踪JDO的DataNucleus。我正在使用Maven，我已经按照增强器的可用说明进行了操作

但是，我得到以下错误：

[datanucleus:enhance]

一般POM答案。只需在pom.xml 3.0.0-release中编写，使版本完全相同。 我希望这是可行的。

阅读后，我找到了解决方案：

    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-core</artifactId>
        <version>3.0.0-release</version>
        <scope>runtime</scope>
    </dependency>

org.datanucleus
数据核核心
3.0.0版本
运行时

核心依赖范围应该是

运行时

我相信我是这样做的（现在请参阅问题中的my pom.xml）

    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-core</artifactId>
        <version>3.0.0-release</version>
        <scope>runtime</scope>
    </dependency>
