Cloud build of GearVR (Android) project doesn't work, but local build from same depot does (5.2.1p2)

Unity Services

Hi

If I build my Gear VR app locally, everything goes well, but the cloud build version fails. There are a few errors in the log file but the one that seems to cause the build to terminate follows…

59146: [Unity] FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_1p2/Unity.app/Contents/VR/Android/ovrplugin.aar does not exist

About 10 lines later I get the same thing formatted differently…

59154: [Unity] Error building Player: FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_1p2/Unity.app/Contents/VR/Android/ovrplugin.aar does not exist

and then 20 lines after that…

59189: [Unity] Player export failed. Reason: Error building Player: FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_1p2/Unity.app/Contents/VR/Android/ovrplugin.aar does not exist

and after another dozen lines, I get the final failure notification. Is there something required to get GearVR support installed on the cloud build servers?

There are some other notes in the log that I think are red herrings, but just incase they’re not I’ll post the full log. It’s too big to upload, but here’s a dropbox link…

We have the same problem with a Gear VR project.

The very first error message in the log is:

Couldn’t open /UNITY_PATH/Unity/Unity-5_2_1f1/Unity.app/Contents/VR/macosx64/OVRPlugin.bundle, error: dlopen(/opt/Unity/Unity-5_2_1f1/Unity.app/Contents/VR/macosx64/OVRPlugin.bundle, 2): Library not loaded: @rpath/LibOVRRT_0.framework/Versions/5/LibOVRRT_0

…which is very similar to the error message that one person in our team gets when he opens the project in the editor. That same person has the problem that Unity crashes when he enters play mode. But this may be unrelated to the build failure of course.

The question is whether Gear VR projects simply don’t work in cloud build or if anyone’s gotten it to work.

Hey all,
This is something we are currently looking into. We’ll post an update as soon as we have more information.

Hey all,
We were able to quickly fix this issue for Unity 5.2.1f1 & 5.2.1p[1-4] , so you should be able to build now using that version with success. The fix is still in the process of rolling out to the rest of the Unity versions affected.

6

Awesome! It works now.

7

Is this still an issue or is it my project? I’m getting the exact same error on 5.2.2

8

Have you tried any of the versions @Ryanc_unity mentioned?

9

[Unity] Couldn’t open /UNITY_PATH/Unity/Unity-5_2_1p3/Unity.app/Contents/VR/macosx64/OVRPlugin.bundle, error: dlopen(/opt/Unity/Unity-5_2_1p3/Unity.app/Contents/VR/macosx64/OVRPlugin.bundle, 2): Library not loaded: @rpath/LibOVRRT_0.framework/Versions/5/LibOVRRT_0

Tried numerous versions and still getting that.

10

Yeah, I get that error too now. It seems to be a regression. Sigh.

11

For what it’s worth, the build seems to work now though the error is still getting thrown.

12

Best I’ve been able to find out, this error spits out when Unity Editor starts, but has no impact on player builds. I’ll send off a bug report to the team about this error.

13

It seems that 5.2.2f1 still suffers from this problem as I unluckily had to find out and given the changes and fixes on the UI for 5.2.2f1, going with 5.2.1 is not an option for our project I fear.

14

Hey Dreamroa,
I just double checked and it appears that we missed fixing a few Unity versions (5.2.2f1 being one of them). I’ll post a reply when we get this resolved.

15

@Dreamora ,

Can you direct message me a link to your project, and also retry a build on 5.2.2 to see if the issue is resolved for you?

16

Hey All,
This should be fixed for all versions going forward with the exception of 5.2.2p2. There are some other issues with the 5.2.2p2 release that I need to forward to the editor team to get fixed.

17

Hey All,
We got a work around in Cloud Build for 5.2.2p2 and newer versions as well as an issue off to the editor team. That should be the last of seeing this issue.

Hi @Ryanc_unity . I managed to get a successful build using 5.2.2p2 as you mentioned, but just so you’re aware: subsequent versions (I tried 5.2.2p4 and 5.2.3f1) aren’t working.

They all have this as the first thing in the log (even the one that worked):

[Unity] Initialize engine version: 5.2.3f1 (f3d16a1fa2dd)
[Unity] Couldn’t open /UNITY_PATH/Unity/Unity-5_2_3f1/Unity.app/Contents/VR/oculus/macosx64/OVRPlugin.bundle/Contents/MacOS/OVRPlugin, error: dlopen(/opt/Unity/Unity-5_2_3f1/Unity.app/Contents/VR/oculus/macosx64/OVRPlugin.bundle/Contents/MacOS/OVRPlugin, 2): Library not loaded: @rpath/LibOVRRT_0.framework/Versions/5/LibOVRRT_0

But the latter versions also produce this error and then fail:

[Unity] FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_3f1/Unity.app/Contents/VR/oculus/Android/ovrplugin.aar does not exist
[Unity] Error building Player: FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_3f1/Unity.app/Contents/VR/oculus/Android/ovrplugin.aar does not exist
[Unity] Player export failed. Reason: Error building Player: FileNotFoundException: /UNITY_PATH/Unity/Unity-5_2_3f1/Unity.app/Contents/VR/oculus/Android/ovrplugin.aar does not exist

Sadly I’m back again, while the missing aar was added on 5.2.2f1 it seems 5.2.3f1 (and potentially 5.3.0f2) are back breaking it even on my Pro subscription.

I guess this is because the build cloud uses a custom version of Unity OSX (the error clearly implies its Unity for OSX) to provide the builds where some files are cut but its definitely troubling our development and making the build health statistics questionable as an indicator if the build cloud actually is a build health issue.

Thanks all,

I’ll get with our team and get these versions updated asap.

Just a bit of knowledge about this issue that might be useful to others:

Unity Cloud Build uses a case sensitive file system (not a custom unity editor), the Editor VR code that points to “VR/oculus/Android/ovrplugin.aar” or in earlier versions “VR/Android/ovrplugin.aar” is the problem as the directory name is actually “android”, not “Android”. We’ve got a bug into the VR team to fix the issue, but until that makes it into a release, we have to resort to using a work around for each version that is broken (simlink Android > android).

Edit: 5.2.2f1, 5.2.3f1, and 5.3.0f2 have been verified fixed.
