apache kafka - Confluent Maven repository not working?

Question

I need to use the Confluent kafka-avro-serializer Maven artifact. From the official guide I should add this repository to my Maven pom

<repository>
  <id>confluent</id>
  <url>http://packages.confluent.io/maven/</url>
</repository>

The problem is that the URL http://packages.confluent.io/maven/ seems to not work at the moment as I get the response below

<Error>
  <Code>NoSuchKey</Code>
  <Message>The specified key does not exist.</Message>
  <Key>maven/</Key>
  <RequestId>15E287D11E5D4DFA</RequestId>
  <HostId>
    QVr9lCF0y3SrQoa1Z0jDWtmxD3eJz1gAEdivauojVJ+Bexb2gB6JsMpnXc+JjF95i082hgSLJSM=
  </HostId>
</Error>

In fact Maven does not find the artifact

<dependency>
  <groupId>io.confluent</groupId>
  <artifactId>kafka-avro-serializer</artifactId>
  <version>3.1.1</version>
</dependency>

Do you know what the problem could be? Thank you

The file is available, since you can download it if you go to it directly: http://packages.confluent.io/maven/io/confluent/kafka-avro-serializer/3.1.1/kafka-avro-serializer-3.1.1.jar

You could try adding the -U flag to your maven command to force download of cached files.

The root of the repo isn't browsable which is why you are getting the message when browsing to http://packages.confluent.io/maven/
