streamsets处理器找不到redis libs

我有两个装有redis和streamset的容器。我想用java编写定制处理器并放到流水线上。但当我将教程中的代码添加到处理器中，将jar发送到lib并尝试启动时，出现了一个异常。你能帮帮我吗？
处理器教程-https://github.com/streamsets/tutorials/blob/master/tutorial-processor/readme.md
redis教程-https://dzone.com/articles/quickstart-how-to-use-redis-on-java

redis:
    image: redis
    ports:
      - 6379:6379
    command: redis-server

  streamsets:
    build:
      context: "."
      args:
        SDC_LIBS: streamsets-datacollector-apache-kafka_2_0-lib                ports:
      - 18630:18630
    volumes:
      - ./user-libs:/opt/streamsets-datacollector-3.9.0/user-libs

在sampleprocessor中启动：

@Override
  protected List<ConfigIssue> init() {
      ....
      Config config = new Config();
      config.useSingleServer().setAddress("redis://redis:6379");
      redisson = Redisson.create(config);
      ... }

  <dependency>
      <groupId>org.redisson</groupId>
      <artifactId>redisson</artifactId>
      <version>3.10.4</version>
      <scope>provided</scope>
  </dependency>

处理器代码测试成功。

问题很可能是您的依赖范围。您已指定 provided ，定义为：
这很像 compile ，但表示希望jdk或容器在运行时提供依赖关系。例如，在为javaenterpriseedition构建web应用程序时，可以将对servlet api和相关javaeeapi的依赖关系设置为scope provided 因为web容器提供了这些类。此作用域仅在编译和测试类路径上可用，并且不可传递。
您应该指定 compile 范围。
