【问题描述】：

我有 2 个 maven 项目，它们都共享一个共同的父项目（用于公共依赖项等）。第一个（P1）是我保留商业模式的地方。另一个（P2）是一个服务层，它使用 P1 中的模型和持久化功能。

P1 pom：

<parent>
    <groupId>com.mycompany</groupId>
    <artifactId>common</artifactId>
    <version>1.0.0</version>
</parent>
<artifactId>P1</artifactId>
<version>0.0.1-SNAPSHOT</version>
...

P2 pom：

<parent>
    <groupId>com.mycompany</groupId>
    <artifactId>common</artifactId>
    <version>1.0.0</version>
</parent>
<artifactId>P2</artifactId>
<version>0.0.1-SNAPSHOT</version>

...

<dependencies>
    <dependency>
        <groupId>com.mycompany</groupId>
        <artifactId>P1</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
...

当我在 Eclipse（运行为... Junit 测试）或终端（mvn clean test）中运行 P1 的单元测试时，它们都工作得很好。但是，当我运行 P2 的单元测试时，它们仅在 Eclipse 中运行（运行为... Junit 测试）。使用 Maven 时，使用 P1 模型的 P2 中的测试失败。

我检查了类路径，唯一的两个区别是

在 Eclipse 中，P1 类的路径指向 P1 目录中的目标文件夹。在 Maven 中，路径是我的本地存储库（应该没问题，因为那里安装了 P1）
在 Eclipse 中，类路径包含对 Java 开发工具 JUnit 运行时支持的引用

我已确认 P1/target 中的文件与 .m2/.../P1.jar 中的文件匹配 - 这包括 META-INF/persistence.xml。

我在单元测试中遇到的错误是同类：

我使用 HyperSQL DB 进行单元测试。

有没有人遇到过这个问题并提出解决方案？

【问题讨论】：

看不到异常的堆栈跟踪或写入的日志。这就是您追踪问题所在的地方。
对不起。使用异常的堆栈跟踪更新问题。
因此它加载了某个对象的字段（Set 类型）。也许某些东西不在 CLASSPATH 中。没有什么比猜测更多的信息在这里是可能的

标签： eclipse maven jdo datanucleus unit-testing

【解决方案1】：

事实证明，由于我没有在我的 persistence.xml 中声明我的类，Datanucleus 正在扫描类路径。这在 Maven 中运行 P1 时效果很好，因为这些类没有隐藏在 jar 文件中。然而，在 P2 中，即使 jar 文件位于类路径中，扫描也没有成功找到类。在 Eclipse 中情况并非如此，因为对 P1 的引用被认为是项目引用 - 因此类不会放置在 jar 文件中。
