Confluent Maven repository not working?

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>
</repository>

The problem is that the URL 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

Needs to add confluent repositories in pom.xml
Please add below lines in the pom.xml

<repositories> <repository> <id>confluent</id> <url> </repository>
</repositories>

The file is available, since you can download it if you go to it directly:

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

Just like you I use a company repository (Sonatype Nexus) and was not able to proxy the confluent's repository.

Then I changed my maven settings.xml to exclude confluent form the mirrored repository:

 <mirrors> <mirror> <id>nexus</id> <mirrorOf>*,!confluent</mirrorOf> <!-- mirror anything but confluent as Nexus cannot proxy it --> <url> </mirror> </mirrors> ... <repositories> ... <repository> <id>confluent</id> <url> </repository> </repositories>

This way, artifacts resolution works for confluents' artifacts as well.

Not as neat as proxying the repo but at least less cumbersome than downloading and registering each dependency manually.

seams jar file removed from http url or http url not working. https url worked for me.

<repositories>
<repository> <id>confluent</id> <url>
</repository>

You can add a mirror in you maven settings file to fetch the jars from confluent repo along with repository config . Changes needed are Add a mirror in settings.xml

 <mirror> <id>confluent</id> <mirrorOf>confluent</mirrorOf> <name>Nexus public mirror</name> <url>
</mirror>

In repository section of maven settings add this

<repository> <id>confluent</id> <url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots>
</repository>

When trying to connect Artifactory to the Confluent Maven repository you have to set the repo URL in Artifactory to be either or (both schemes seem to work fine). The confusing part is that when you ask Artifactory to test that URL it will fail with the message "Input may not be null". You are also unable to browse the repository in Artifactory. However, regardless of these problems, artifacts will be downloaded and cached when clients request them.

Had issue with:

<repositories> <repository> <id>confluent</id> <url> </repository>
</repositories>

working:

<repositories> <repository> <id>confluent</id> <url> </repository>
</repositories>

Changed "http" with "https" worked for me as maven has blocked the HTTP due to security reasons.

Adding confluent repository worked in POM file for Maven project.

Use below in build.sbt for SBT projects

resolvers += "confluent" at ""
