java -jar错误信息如下：
Exception in thread "main" com.typesafe.config.ConfigException$UnresolvedSubstitution: reference.conf @ jar:file:flinkdemo-1.0-SNAPSHOT-jar-with-dependencies.jar!/reference.conf: 875: Could not resolve substitution to a value: ${akka.stream.materializer}
解决方法
pom.xml的maven-shade-plugin插件的executions->execution->configuration->transformers节点中增加
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>reference.conf</resource>
</transformer>
