[SOLVED] Compiler won't execute in existing project after upgrading from Unity 5.5 to the 5.6 beta

Unity Engine

First of all, apologies if this is the wrong place for this - I’ve posted on stackoverflow, unity answers, and /r/Unity3D without any help so far, so I came here. If this type of support post doesn’t belong here, please let me know and I’ll delete the thread!

Things I’ve tried:

  • Deleting the Library and Temp/Obj folders, three times now (rebuilding library each time) with no change.
    • I’ve removed my alternate compiler (Incremental Compiler.)
    • Reinstalled Unity 5.6.0b3 beta - no change.
    • Upgraded to Unity 5.6.0b7 - no change.
    • There is no alternate UnityEditor.dll in my Assets folder.

Creating a new project with Standard Assets only works fine and can be compiled.

Here’s a picture of the error:

Could not start > compilationMissingMethodException: > Method not found: > ‘UnityEditor.Scripting.Compilers.MonoScriptCompilerBase.GetProfileDirectory’. > UnityEditor.Scripting.Compilers.ScriptCompilerBase.BeginCompiling > () (at > C:/buildslave/unity/build/Editor/Mono/Scripting/Compilers/ScriptCompilerBase.cs:40)

NullReferenceException: No clue why my console is flooded with this error...

Hi matteumayo,
Could you please submit a bug report with the project and reply with the case # in here?

Thanks for the reply. Sorry it’s taken me so long to respond, I’ve been really busy and unable to work on this issue.

I submitted a bug report with the project today, case number: 886880

Before you spend any time on this, I think I’ve fixed it by removing the 3rd-party Incremental Compiler.

This was actually one of the first things I tried, as it’s obvious, but it didn’t seem to do anything. I think this is because, for whatever reason, I had to restart Unity after removing the Incremental Compiler, otherwise the compiler error still occurred and it wouldn’t execute.

I found this by adding assets from my project to a fresh project, one by one, and found the error when I added the ICompiler.

I think the first time troubleshooting I made the mistake of assuming it wasn’t the incremental compiler due to my lack of restarting - although to be honest I’m surprised I made such a stupid mistake!

I’ll mark this thread solved and close my bug report as soon as I verify 100% that this was the cause.

Confirmed this was the issue.
