Question

在依赖检查警告的驱动下，我们尝试使用spring-kafka：2.2.7将org.apache.kafka：kafka-clients的版本提高到我们设置中的2.2.1版本。

结果是，在代理启动期间，使用EmbeddedKafkaRule的测试失败，并出现IOException声明“无法加载/ some / path ..”

我们确保在类路径上没有冲突版本的kafka-clients，并尝试将EmbeddedKafkaRule的logs.dir指定到maven的目标文件夹下的某个文件夹中，在上述示例中为“ target / embedded-kafka” 。两者都没有成功。

有人有相同的问题并解决吗？

我刚刚进行了测试，没有任何问题。

您是否遵循the documentation about overriding kafka client versions?中的说明。

当在2.1.x kafka-clients jar中使用spring-kafka-test（2.2.x版）时，您需要覆盖某些传递依赖项，如下所示：

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
    <version>${spring.kafka.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka-test</artifactId>
    <version>${spring.kafka.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka_2.11</artifactId>
        </exclusion>
    </exclusions>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>2.1.1</version>
</dependency>

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>2.1.1</version>
    <classifier>test</classifier>
</dependency>

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.12</artifactId>
    <version>2.1.1</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.12</artifactId>
    <version>2.1.1</version>
    <classifier>test</classifier>
    <scope>test</scope>
</dependency>

请注意，当切换到Scala 2.12（建议用于2.1.x及更高版本）时，必须从spring-kafka-test中排除2.11版本。
