【问题描述】：
嘿，我正在尝试让一个 Maven Java 项目通过 Jenkins 构建运行，它通过命令行完美运行，但是当我通过 Jenkins 运行它时。我收到此错误：
Unable to make field private final java.util.Comparator java.util.TreeMap.comparator accessible: module java.base does not "opens java.util" to unnamed module @425ea9cb
这是完整的堆栈跟踪

Finished: FAILURE
Jenkins 甚至没有从存储库中签出代码，它在 Windows 机器上，Java 版本是 10 有人可以帮忙吗？
【问题讨论】：
-
要关注的区域无法使字段私有 final java.util.Comparator java.util.TreeMap.comparator 可访问：模块 java.base 没有“打开 java.util”到未命名的模块@425ea9cb
-
xstream 似乎试图破解 Tree.comparator，似乎在这里被跟踪：github.com/x-stream/xstream/issues/101。也就是说，我会期待“非法反射访问”警告而不是 InaccessibleObjectException。 Jenkins 是否使用 --illegal-access=deny 运行？
