## AI overview

A troubleshooting guide for missing Codename One builds after migration to the new build cloud. It explains that outdated client libraries in IDE plugins can cause builds not to appear, queue errors, or connection errors, and recommends updating the plugin and project libraries.

## Source excerpt

A while back we announced the migration to the new build cloud. The migration worked very smoothly and mostly seamlessly but there was one caveat: client libraries must be up to date. This is a confusing point so hopefully this long overdue post will clarify it. The core of the problem is CodeNameOneBuildClient.jar. It's a relatively simple jar with a few ant tasks that performs a lot of "under the hood" services such as sending the build to the cloud. It's shipped within the IDE plugin and old versions of the IDE plugins would replace it automatically. We now update it via the update framework which is better but might cause a few issues.
