Java 如何让JUnit5与JDK10（jigsaw）和Maven3一起工作？

我和一些朋友一起开发了一个JDK10应用程序，它使用jigsaw特性集（在jdk9中引入）和junit5以及maven作为构建管理

但是，如果我们尝试使用Maven运行测试，总是会得到一个不可访问的对象异常 例外情况如下：

[ERROR] resourceSchedule  Time elapsed: 0.001 s  <<< ERROR!
java.lang.reflect.InaccessibleObjectException: Unable to make de.truncated.framework.shared.resources.ResourceManagerTest() accessible: module de.truncated.framework.shared does not "opens de.truncated.framework.shared.resources" to unnamed module @ed7f8b4

---

[ERROR]resourceSchedule经过的时间：0.001秒今天，我找到了两种解决该问题的方法

1） 您可以添加--add opens to surefire插件配置：

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M1</version>
    <configuration>
        <argLine>--add-opens de.truncated.framework.shared/de.truncated.framework.shared.resources=ALL-UNNAMED</argLine>
    </configuration>
</plugin>


maven surefire插件
3.0.0-M1
--添加打开de.truncated.framework.shared/de.truncated.framework.shared.resources=ALL-UNNAMED

这将起作用，因为默认情况下，surefire插件会向surefireargs文件添加--add reads，而JUnit5使用的反射“reads”是不够的

2） 或者，您可以将所有JUnit5测试类（及其带注释的方法）标记为public。这也会有所帮助，因为在这种情况下，JUnit在运行测试时不会使用反射（至少在版本5.3.1中不会）

另外，我使用了maven编译器插件版本3.8.0和maven surefire插件版本3.0.0-M1。
目前将由解决，您需要--“add opens MODULE/PACKAGE=org.junit.platform.commons”见Ok，如果我从WearedDeveloper大会回来，我将尝试一下，谢谢。作为补充说明，
--允许非法访问
在JDK 10中未被删除，因为它在JDK 9 GA中不存在。它在一些JDK 9 EA版本中被替换为，但在JDK 10中仍然可用。好的，谢谢您的提示@MarkReinhold非常感谢！
