自定义了一个函数geo:getGeohashCode，在纯siddhi环境中可以正常运行，在flink-siddhi环境下，按文档的要求增加了函数的注册 SiddhiCEP cep = SiddhiCEP.getSiddhiEnvironment(env); cep.registerExtension("geo:getGeohashCode", GetGeohashCode.class); 在Idea编译器中可以正常运行，执行jar包抛出异常： org.apache.flink.client.program.ProgramInvocationException: The main method caused an error: Error on '1136e420-2a7d-4f2b-82df-7f674737add3' @ Line: 3. Position: 128, near 'geo:getGeohashCode(lat, lon, 10)'.
