我有一个项目，其中主方法类“Bootstrap.class”位于 src/test 文件夹中。所以我曾经<classpathScope>test</classpathScope> 能够执行

mvn exec:java

我的问题：我得到一个“java.lang.IllegalArgumentException：未知实体：”因为我正在导入位于 main/java.xml 的某些类。关于如何解决这个问题的任何想法？

这是我的Pom：

尝试使用exec目标而不是java使用类路径参数，如此处所述https://www.mojohaus.org/exec-maven-plugin/examples/example-exec-for-java-programs.html

这将分叉 JVM 并可能解决很多问题，尤其是使用像 Hibernate 这样的工具，这些工具可以进行非平凡的类加载。这是因为 Maven 不必使用类加载器魔法来提供正确的进程内类路径（Maven 是 java 进程本身，它以简单的类路径开始，仅包括 maven 引导 jars）。这样，它只会填充 -cp 参数，并分叉新进程：诊断简单易行。

我解决了这个问题。问题是我有 2 个 persistence.xml 一个用于测试/资源中的测试，另一个用于主/资源中的应用程序。我不得不删除 test/resources 中的那个，并在应用程序 persistence.xml 添加另一个持久性单元。

请参阅：如何配置 JPA 以在 Maven 中进行测试
