How do you configure the spring integration poller after XSD changes have invalidated the fixed-dela-CodePudding

Original xml:

<int:poller default="true" task-executor="stepTaskExecutor" fixed-delay="1000">

The fixed-delay attribute is no longer legal, and fails XML parsing in the (eclipse) IDE.

Alternative configuration: An alternative suggested elsewhere (including https://docs.spring.io/spring-integration/docs/2.0.0.M3/spring-integration-reference/html/samples.html):

<!-- Globally scoped Spring Integration bean resources -->
<!-- see https://stackoverflow.com/questions/73450768/how-to-configure-channels-and-amq-for-spring-batch-integration-where-all-steps-a/73455134#73455134 -->
<!-- see https://stackoverflow.com/questions/28625635/attribute-fixed-rate-is-not-allowed-to-appear-in-element-intpoller -->
<int:poller default="true" task-executor="stepTaskExecutor">
    <int:interval-trigger interval="1000"/>
</int:poller>

This passes the XML parsing in the IDE, but fails at runtime

Please advise.

Use Spring Tool Suite (eclipse), or add the spring tools plugin to your eclipse so that the schema is loaded from the jar file instead of from the internet.
