IDE Provisioner

A plugin compatibility check has been added to IDE Provisioner and is enabled by default. With this upgrade, all newly uploaded plugin versions are automatically verified for compatibility with the IDE, preventing the provisioning and installation of unsupported or mismatched plugins.

If end users experience issues with existing plugins (uploaded before the upgrade), you can run a manual compatibility check to identify and exclude the plugins causing the problems.

To run the compatibility check, execute one of the following API requests:

• POST /api/plugins/compatible-ides/recalculate-all

  Use this endpoint if you have fewer than 10,000 plugins (including all versions). Calling this endpoint triggers plugin compatibility calculation for all plugins uploaded before the upgrade.

• POST /api/plugins/compatible-ides/recalculate

  Use this endpoint if you have more than 10,000 plugins (including all versions). It allows you to trigger plugin compatibility calculation for specific plugins, helping to avoid server overload when determining compatible IDEs. Provide a list of plugin IDs in the request body, as shown in the example below:

  curl -X POST --location "https://<your_organization>/api/plugins/compatible-ides/recalculate" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer <token>" \ -d '{ "pluginIds": ["aws.toolkit", "com.jetbrains.kmm"] }'

IDE Services Core

• Server configuration properties:

  • tbe.download.cdn-domains

  • tbe.download.extra-cdn-domains

  have been changed.

  These properties now require a URL schema (http:// or https://) to be explicitly specified for all their values.

  If you haven't changed these properties, you don't need to do anything. This change will affect you only if tbe.download.cdn-domains or tbe.download.extra-cdn-domains configuration properties have been customized. With this change, configuration values formatted like in the following example will no longer work:

  tbe: download: cdn-domains: - 'download.jetbrains.com' # won't work; same with extra-cdn-domains

  To fix the issue, simply specify the schema explicitly:

  tbe: download: cdn-domains: - 'https://download.jetbrains.com'

  To avoid accidental misconfiguration, we have added a validation step to the server startup process. If there is a CDN domain entry without an explicit schema, the server will fail on startup with error.

• Management endpoint configuration properties were updated to align with Spring Boot 3.x standards. Existing configurations continue to work. If you use custom configuration, updating to the new property names and values is recommended.

  The following properties have been changed:

  • management.endpoints.enabled-by-default to management.endpoints.access.default
    Value mapping: true → unrestricted, false → none

  • management.endpoint.<name>.enabled to management.endpoint.<name>.access
    Value mapping: true → unrestricted, false → none

  • management.metrics.export.prometheus.enabled to management.prometheus.metrics.export.enabled

  • spring.codec.log-request-details to spring.http.codecs.log-request-details
