java.lang.reflect.InaccessibleObjectException：无法使字段私有最终java.util.Comparator java.util.TreeMap.comparator可访问：模块

问题描述 投票：0回答：4

这是我的第一个黄瓜项目，我在设置所有内容时遵循了教程。一切似乎都是一样的，但出于某种原因我得到了这个：

java.lang.ExceptionInInitializerError。 导致：java.lang.reflect.InaccessibleObjectException：无法使字段私有最终java.util.Comparator java.util.TreeMap.comparator可访问：模块java.base不会“打开java.util”到未命名模块@74ad1f1f

知道如何解决这个错误吗？

下面我发布了控制台中出现的所有内容以及我的 pom 文件，以防我的依赖项出现问题，尽管教程的 pom 文件中的人员是相同的。

这就是我的控制台中显示的所有内容。

需要在jvm选项中添加一些指令。
我在idea2022上添加的，这是我的步骤。
小路： 

Run—>EditConfigurations…—>Modify options—>JAVA Add VM options—>VM options

选项： 
--add-opens java.base/java.util=ALL-UNNAMED

顺便说一下，它还有其他选项：

--add-opens java.base/java.lang=ALL-UNNAMED
--add-opens java.base/java.nio=ALL-UNNAMED
--add-opens java.base/sun.nio.ch=ALL-UNNAMED

希望可以帮助您解决问题

我解决了我的问题。结果发现 eclipse 自动下载并使用的 JRE 与这个版本的 cucumber 不兼容。我手动更改了 ProgramFilex(x86)/Java 文件夹中 jre 1.8 的路径，现在一切正常。

添加 @GhostXu 所写的内容，如果您使用 Maven，则可以将 

<argLine>
添加到 
pom.xml
中的 Surefile 配置中。类似的东西

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-surefire-plugin</artifactId>
 <configuration>
    <argLine>--add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED</argLine>
  </configuration>
</plugin>

如果使用 Gradle 而不是 maven，您可以将以下块添加到 build.gradle 文件中，以便在运行时自动将适当的 JVM 参数添加到测试中，而不是手动配置。这可以用作权宜之计，直到发布新的库版本，或者根据您的情况重构测试以符合新标准。

tasks.withType(Test).configureEach {
    jvmArgs = jvmArgs + ['--add-opens=java.base/java.util=ALL-UNNAMED']
}
