How to get JUnit5 with JDK10 (jigsaw) and Maven3 to work?(如何让JUnit5与JDK10(Jigsaw)和Maven3一起工作?)
问题描述
我和一些朋友一起开发了一个JDK 10应用程序,该应用程序使用Jigsaw特性集(在jdk9中引入)和Junit5,并使用maven作为构建管理。 但是,如果我们尝试使用Maven运行测试,我们总是会得到一个无法访问的对象异常 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
我从几天起就在谷歌上搜索...在jdk9中,它可以简单地用--许可-非法访问来寻址,但在jdk10中这是不可能的,因为这个标志被删除了。来自Junit5和GitHub上的其他人的jdk10代码示例并没有像看起来那样使用拼图。
所以看起来我在maven、模块或JVM args配置中遗漏了一些重要的东西。 如果有人能在这件事上提供帮助就太好了。
非常感谢!
该项目的一些其他信息可能会对您有所帮助:
- 主要代码由一个模块信息文件配置,该文件向每个人导出(而不是打开)(它是一个类似于代码库的框架)
- 测试代码未模块化
- 当前未应用JVM参数

推荐答案
今天我找到了该问题的两个解决方案。
1)您可以添加--添加-打开至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>
这是可行的,因为默认情况下,surefire插件添加--添加--读取到sureFireargs文件,而JUnit5使用反射,而"读取"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)标记为公共。这也会有所帮助,因为在这种情况下,JUnit在运行测试时将不会使用反射(至少在5.3.1版中不会)。
附注:我使用的是maven-编译器-plugin版本3.8.0和maven-surefire-plugin 3.0.0-M1。
