maven - Kapt 无法与 OpenJDK 16 一起正常工作

Question

我有一个将 Kotlin 1.5.0 和 Kapt 用于映射结构的应用程序。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 Unresolved 问题:https://youtrack.jetbrains.com/issue/KT-45545 ，我正在尝试使用 --add-opens 作为 kotlin-maven-plugin 中的 args 选项，但似乎它们无法正常工作:

                </dependency>
            </dependencies>
</plugin>

当我用这个 args 选项再次执行 maven 时会告诉我以下内容:

[WARNING] Flag is not supported by this version of the compiler: -X--add-opens=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED

如何将这些选项添加到 kotlin-maven-plugin？

使用 JDK 16 和 maven 运行 Kapt 是否还有其他可能性？

根据 JetBrains comment :
添加 org.gradle.jvmargs=--illegal-access=permit至 gradle.properties
