Tengo una aplicación que usa Kotlin 1.5.0 y Kapt para mapstructs. He actualizado mi JDK a 16 y me sale el siguiente error de compilación:

He visto que hay un problema abierto con Kapt y JDK 16: https://youtrack.jetbrains.com/issue/KT-45545 , estoy tratando de usar --add-opens como opciones de argumentos en kotlin-maven -plugin pero parece que no funcionan correctamente:

 <plugin> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-plugin</artifactId> <executions> <execution> <id>kapt</id> <goals> <goal>kapt</goal> </goals> <configuration> <sourceDirs> <sourceDir>src/main/kotlin</sourceDir> <sourceDir>src/main/java</sourceDir> </sourceDirs> <annotationProcessorPaths> <annotationProcessorPath> <groupId>org.mapstruct</groupId> <artifactId>mapstruct-processor</artifactId> <version>${mapstruct.version}</version> </annotationProcessorPath> </annotationProcessorPaths> </configuration> </execution> </executions> <configuration> <args> <arg>-Xjsr305=strict</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED</arg> <arg>-X--add-opens=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED</arg> </args> <compilerPlugins> <plugin>spring</plugin> </compilerPlugins> </configuration> <dependencies> <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-allopen</artifactId> <version>${kotlin.version}</version> </dependency> </dependencies> </plugin>

cuando vuelvo a ejecutar maven con estas opciones de argumentos me dice lo siguiente:

• ¿Cómo puedo agregar estas opciones a kotlin-maven-plugin?
• ¿Hay alguna otra posibilidad de ejecutar Kapt con JDK 16 y maven?
