Perforce plugin unusable with a Perforce Helix Core Cloud server

[nrgill28]

When trying to connect to our newly set up Perforce Helix Core Cloud server I get the following error: "Your client does not support Helix Core Cloud. Upgrade to version 2021.2/2201121 or later". The server then rejects the connection completely, making the Perforce plugin unusable. From what I can tell, the version of the P4 API included in the plugin right now is still 2019.1.

While troubleshooting I found a community maintained updated version of the Perforce plugin in a repo over on the Perforce GH org: https://github.com/perforce/unity-p4-plugin. This alternative plugin has worked for me but requires overwriting the plugin executable included in the Unity Editor install directory, which is not ideal. It also seems to not be under the same license so maybe that's why they didn't want to upstream the changes? Not sure.

In any case it would be good if the P4 API was updated here so that Helix Core Cloud servers would be supported OOTB.

Thanks for reporting this. It has also been discussed in https://discussions.unity.com/t/your-client-does-not-support-helix-core-cloud-upgrade-to-version-2021-2-2201121-or-later/1661332/12, where I also posted an internal build with the Perforce Plugin to P4 C++ API 2021.2/2201121: builds.zip (12.3 MB)

If you are wiling to try it, you have to unzip the corresponding executable (OS-dependent) to replace the one used by your Unity Editor installation, for instance: C:\Program Files\Unity\Hub\Editor\6000.0.54f1\Editor\Data\Tools\VersionControl\PerforcePlugin.exe

Let me know how it goes
