我向集群提交了flink(v1.10.0(作业，但显示了以下错误：

在运行时似乎找不到RMQConnectionConfig，如何在系统范围内添加jar并使我的任务jar又小又薄？这是我的grade.build依赖项：
dependencies {
// --------------------------------------------------------------
// Compile-time dependencies that should NOT be part of the
// shadow jar and are provided in the lib folder of Flink
// --------------------------------------------------------------
compile "org.apache.flink:flink-java:${flinkVersion}"
compile "org.apache.flink:flink-streaming-java_${scalaBinaryVersion}:${flinkVersion}"
// --------------------------------------------------------------
// Dependencies that should be part of the shadow jar, e.g.
// connectors. These must be in the flinkShadowJar configuration!
// --------------------------------------------------------------
//flinkShadowJar "org.apache.flink:flink-connector-kafka-0.11_${scalaBinaryVersion}:${flinkVersion}"
compile "log4j:log4j:${log4jVersion}"
compile "org.slf4j:slf4j-log4j12:${slf4jVersion}"
compile "com.rabbitmq:amqp-client:4.2.0"
compile "com.alibaba:fastjson:1.2.57"
compile "org.apache.flink:flink-connector-rabbitmq_${scalaBinaryVersion}:1.10.0"
}
如果你想让jar包含dist.jar文件，你应该写这样的依赖项：
flinkShadowJar "com.rabbitmq:amqp-client:4.2.0"
flinkShadowJar "com.alibaba:fastjson:1.2.57"
flinkShadowJar "org.apache.flink:flink-connector-rabbitmq_${scalaBinaryVersion}:1.10.0"
它将把依赖关系打包到distjar文件中，并在运行时使用。
