New artifact version is not listed after publishing to Maven Central

Question

We recently published a new version of existing artifacts. The version shows up if I explicitly type the version number in the URL.

• https://mvnrepository.com/artifact/com.microsoft.azure.functions/azure-functions-java-library-rabbitmq/2.0.0-preview
• https://search.maven.org/artifact/com.microsoft.azure.functions/azure-functions-java-library-rabbitmq/2.0.0-preview/jar

But they are not listed on the artifact page.

• https://mvnrepository.com/artifact/com.microsoft.azure.functions/azure-functions-java-library-rabbitmq
• https://search.maven.org/artifact/com.microsoft.azure.functions/azure-functions-java-library-rabbitmq

Is this is an issue with naming of the version or change in some other properties (I made quite a few) in the POM file?

Answer 1

It seems to take a few days before the new version gets listed. It would be good to know the reason for this delay. mvnrepository.com now shows 2.0.0-preview version. I expect search.maven.org to also show it in a couple of days.

Answer 2

Publication takes around 30 minutes, while the search engine might take several hours to be updated.

Quoting from the Central repository guide :

Upon release, your component will be published to Central: this typically occurs within 30 minutes, though updates to search can take up to four hours.
