它看起来像是 flink-gelly 没有出现在jar文件中。这个问题最明显的原因是项目的pom文件中缺少maven依赖项。但是我假设依赖性是存在的，否则在ide中开发作业是不可能的。
jar文件很可能是由 maven-jar-plugin ，不包括依赖项。尝试将以下片段添加到 pom.xml :

<build>
    <plugins>
        <!-- We use the maven-shade plugin to create a fat jar that contains all dependencies
        except flink and it's transitive dependencies. The resulting fat-jar can be executed
        on a cluster. Change the value of Program-Class if your program entry point changes. -->

现在，您可以使用 mvn clean package -Pbuild-jar . jar文件现在将位于 target/ 目录。
您可以手动检查jar（zip）文件中是否包含类文件 /org/apache/flink/graph/
