我试图用apach flink v运行这个例子Sentence Encoder。1.17.0
但是当我启动应用程序时,我得到了错误

Exception in thread "main" org.apache.flink.runtime.rpc.exceptions.RpcLoaderException: Could not load RpcSystem.
    at org.apache.flink.runtime.rpc.RpcSystem.load(RpcSystem.java:106)
    at org.apache.flink.runtime.minicluster.MiniCluster.lambda$new$0(MiniCluster.java:253)
    at org.apache.flink.runtime.minicluster.MiniCluster.start(MiniCluster.java:339)
    at org.apache.flink.client.program.PerJobMiniClusterFactory.submitJob(PerJobMiniClusterFactory.java:77)

不明白为什么它会导致,即使简单的文本服务器由ncat启动(在WIN上)。

它看起来像一些新的例外,因为我没有找到任何主题像这一个。
在调试模式下,当尝试继续执行**Iterator iterator = ServiceLoader.load(RpcSystemLoader.class).iterator();**在RpcSystem类

你在这里有依赖关系,这没有太大意义(像flink-shaded-asm-9flink-shaded-guavaflink-rpc-core等)。在https://nightlies.apache.org/flink/flink-docs-release-1.17/docs/dev/configuration/overview/上解释了你需要在那里有什么。
为了运行DataStream API应用程序,我只期望:

<!-- These dependencies are provided, because they should not be packaged into the JAR file. -->
        <dependency>
            <groupId>org.apache.flink</groupId>
            <artifactId>flink-streaming-java</artifactId>
            <version>${flink.version}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.flink</groupId>
            <artifactId>flink-clients</artifactId>
            <version>${flink.version}</version>

如果使用快速入门示例,这些也是依赖项。
