我在运行Docker镜像时遇到错误。我用gradle创建了一个核心java应用程序。
使用docker build命令创建docker镜像，在运行docker镜像时，我得到以下错误

Error: A JNI error has occurred, please check your installation and try again

我可以看到错误是由于缺少Kafka消费者库，但我无法理解我在docker文件中遗漏了什么导致了这个问题。
这里是dockerfile

FROM openjdk:8
ADD build/libs/*.jar parallel.jar

RUN bash -c 'touch /parallel.jar'
ENTRYPOINT ["java", "-jar", "parallel.jar"]

在运行docker build命令之前，我确保运行了gradle clean build命令。
以下是我在build.gradle中使用的依赖项

    implementation "org.apache.avro:avro:1.11.1"
