Snapshot dependency cannot be updated

I encountered a problem today. A colleague from the rookie upgraded the jar package version, but only released some libraries (for example, only the common is released, but not the client). I upgraded the corresponding jar package version locally, and found that the client-related tools are missing , and after colleagues supplement released client, I try the local reload / invalidate not work, check the last maven configuration under the guidance of brothers Always update snapshotsoption is resolved.
The possible reason is that after the snapshot is updated once, it is stored in the local cache. Even if new content is released, reload/invalidate are all taken from the local cache, and naturally no new content can be obtained.
