springcloud引入kafka报错：Cannot resolve symbol 'annotation'？

Question

pom.xml

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-kafka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-stream-kafka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream</artifactId>
        </dependency>

版本号：/Users/zhangwei/.m2/repository/org/springframework/cloud/spring-cloud-starter-stream-kafka/3.1.1/spring-cloud-starter-stream-kafka-3.1.1.pom

xxx.java

import org.springframework.messaging.annotation.Input;


public interface KafkaStream {
    String INPUT = "click-events-in";
    String OUTPUT = "click-events-out";

    @Input
    SubscribableChannel clickEventsIn();

    @Output
    MessageChannel clickEventsOut();
}

上面引入的jar包Input报：Cannot resolve symbol 'annotation'

Answer 1

版本可能冲突了，只保留这个试试

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-stream-kafka</artifactId>
</dependency>
