我有一个将 Kotlin 1.5.0 和 Kapt 用于 mapstructs 的应用程序。我已将 JDK 更新为 16，但出现以下编译错误：
Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.5.0:kapt (kapt) on project X: Compilation failure
java.lang.IllegalAccessError: class org.jetbrains.kotlin.kapt3.base.KaptContext (in unnamed module @0x248e24b) cannot access class com.sun.tools.javac.util.Context (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.util to unnamed module @0x248e24b

我已经看到 Kapt 和 JDK 16 存在一个未解决的问题：https ://youtrack.jetbrains.com/issue/KT-45545 ，我正在尝试使用--add-opens作为 kotlin-maven 中的 args 选项-plugin 但似乎它们无法正常工作：
<plugin>

当我使用这个 args 选项再次执行 maven 时，会告诉我以下信息：

- 如何将这些选项添加到 kotlin-maven-plugin？
- 是否有任何其他使用 JDK 16 和 maven 运行 Kapt 的可能性？
