The following are the limitations of JetBrains Plugins repositories in Artifactory:
Anonymous Access and Read-Only Operations: JetBrains Plugins repositories in Artifactory do not support authentication due to a client-side limitation in the IDEs. This means that connecting to a private extension marketplace with credentials is not yet supported. All connections to JetBrains Plugins repositories are treated as anonymous and all operations for this repository type are read-only.
Support for JFrog Curation: JetBrains repositories in Artifactory do not currently support integration with JFrog Curation. Support is planned for a future release.
