JDO（datanucleus）单元测试在Eclipse中运行良好但在Maven中失败

我有两个maven项目，它们共享一个共同的父项目（对于公共依赖项等）。第一个（P1）是我保留业务模式的地方。另一个（P2）是一个服务层，它使用P1中的模型和持久性功能。

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中运行P1的单元测试（运行为... Junit测试）或在终端（mvn清洁测试）中，它们都工作得很好。但是，当我运行P2的单元测试时，它们只能在Eclipse中运行（Run as ... Junit test）。使用Maven时，P2中使用P1模型的测试失败。

我检查了类路径，只有两个区别是

  • 在Eclipse中，P1类的路径是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P1安装在那里）

  • 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。

我在单元测试中得到的错误是相同的：

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？

1 个答案:

答案 0 :(得分：0)

事实证明，由于我没有在persistence.xml中声明我的类，因此Datanucleus正在扫描类路径。这在运行P1时在Maven中运行良好，因为类不会存放在jar文件中。但是在P2中，即使jar文件在类路径上，扫描也没有成功找到类。 Eclipse中不是这种情况，因为对P1的引用被认为是项目引用 - 因此类不会放在jar文件中。
