iOS Library PackageCache Error with ProBuilder

We have really been enjoying Could Build but have recently run into some issues with the new version of Unity and ProBuilder.

Our project was recently upgraded to 2018.3.0f2 and installed the newest version of ProBuilder 3.0.9. We are using Bitbucket with Sourcetree and our Library folder is not in our repository because of its large size. The Bitbucket project has been directly setup to build from our master in Cloud Build. Doing a Cloud Build for iOS with the new version of Unity and ProBuilder seems to make the build fail and get this error:

"[Unity] Library/PackageCache/com.unity.probuilder@3.0.9/ProBuilder/Editor/Addons/pb_Fbx.cs"

Removing ProBuilder from our project and then running the build on Cloud Build for iOS again results in a successful build. As far as I have read we shouldn't need the Library folder in our repo when doing a Cloud Build. Since it was referencing "FbxExporters" we installed the FBX Exporter package but that did not resolve the error.

Unity Version: 2018.3.0f2
XCode Version: Selected "Latest Compatible Version" in Cloud Build
Source Control: Bitbucket with SourceTree
Wwise Version: 2018.1.3.6784

None of us have Mac's so we are unable to test this locally for an iOS build.

Assembly with name 'Unity.ProBuilder.AddOns.Editor' already exists (Assets/_LocalPackages/botd.com.unity.probuilder/ProBuilder/Editor/Addons/Unity.ProBuilder.AddOns.Editor.asmdef)
