如何使用JDK10(jigsaw)和Maven3来运行JUnit5？

Jan*_* S. 5 java maven-3 java-platform-module-system java-10 junit5

我和一些朋友一起使用jdk 10应用程序,它使用jigsk功能集(在jdk9中引入)和junit5和maven作为构建管理.

但总是如果我们尝试使用Maven运行测试,我们会得到一个InaccessibleObjectException异常,例如:

[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

我现在谷歌搜索...在jdk9它可以简单地使用--permit-illegal-access,但这在jdk10中是不可能的,因为这个标志被删除了.来自junit5的jdk10代码示例和github上的其他代码不会使用拼图看起来如何.

所以看起来我错过了maven,module或jvm args config中的一些主要内容.如果有人可以就此事提供帮助,那将是非常好的.

非常感谢你!

项目的一些额外信息可能会有所帮助:

主代码由模块信息文件配置,该文件导出(不打开)给每个人(它的代码库之类的框架)
测试代码没有模块化
目前没有应用jvm args

今天我找到了两个解决这个问题的方法。

1) 您可以将 --add-opens 添加到 surefire 插件配置中：

<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>

这会起作用，因为默认情况下surefire插件将--add-reads添加到surefireargs文件中，而JUnit5使用反射，“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（好吧，至少在 5.3.1 版中不会）。

PS 我使用了 maven-compiler-plugin 版本 3.8.0 和 maven-surefire-plugin 3.0.0-M1。
