为 RabbitMQ 添加依赖项时 JBPM 失败

如何解决为 RabbitMQ 添加依赖项时 JBPM 失败

我正在尝试编写一个 JBPM 流程，其中包含一个向 RabbitMQ 发送消息的任务。

在这样做之前，我编写了一个 Java 程序来编写相同的消息，并且成功了。对于那个程序，我在 pom.xml 中使用了以下依赖项：

<dependency>
    <groupId>com.rabbitmq</groupId>
    <artifactId>amqp-client</artifactId>
    <version>5.10.0</version>
</dependency>

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.5</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.10.0.pr2</version>
</dependency>

所以希望在 JBPM 中具有相同的功能，我去了设置和依赖项。我只是先添加依赖项：还没有 Java 代码。

我先添加了依赖 commons-lang3，我的 JBPM 流程（没有 RabbitMQ 逻辑）仍然有效。

然后我添加了依赖 jackson-databind，我的 JBPM 进程（仍然没有 RabbitMQ 逻辑）仍然有效。

然后我添加了依赖 amqp-client，我的 JBPM 进程（仍然没有 RabbitMQ 逻辑）失败如下：org.jboss.resteasy.spi.UnhandledException: java.lang.NoClassDefFoundError: Lcom/codahale/metrics/MetricRegistry;

让我强调：我没有添加任何代码。只有三个依赖项。

希望有人能帮忙。

完整的堆栈跟踪如下。
