Nothing changed and got the the same compilation errors like before. Now I’m removing all assets but the Assets folder from my Unity Project (my solution to solve this problem).
I am curious… are you by any chance using any kind of 3rd party assets (assets you have bought or got for free) ??? i am asking this as it may help the Unity team to solve it if it is in fact in their control 
because like anything else it could also be something with a certain asset you use try to eliminate every asset you have by deleting or moving one folder at a time 
I use many assets my employers have bought, and free ones as well as my own assets I made in Blender. It’s a problem connected with dlls. Now, I’m rebuilding my big project so Unity is busy. I upgraded my project from Unity 4.6 to 5.0. There can be an asset in my Unity Project that is incompatible with Unity 5.0. Which one it’s hard to guess. I removed all dlls from the project, from the Plugins folder and from the Editor folder. Such assets like .jpg, .fbx, etc have no influence which version of Unity is being used. I noticed that it could be caused by importing scripts only because I had a rebuilt Unity Project and no compilation errors. But I needed some Standard Assets so imported the scripts and… I got the compilation errors.
What can be in the scripts that prevent from compiling project? The scripts should be compiled again to make no compilation errors (I remove all stuff from my Unity Project and only the Assets folder is left).
By the way, the rebuilding of my big project is very irritating because I lose much time.
Yep it’s probably one of the assets causing this problem.
I had the same thing happen with a few assets, although they import fine with no errors. when it comes to building on android it fails.
I now just build after importing a heavy scripted asset. models, audio etc wont be a problem.
How to find this asset in such a complicated project? Removing one folder at a time will last very long because I need rebuild the project every time to see if I’m successful. The Editor Log won’t help me to find the faulty asset.
compilation errors are how you find the problem… unless for some reason, the error message is vague and doesn’t have any information. but they usually do.
post your compiliation errors.
I posted my logs and nobody was able to find the reason of the compilation errors.

If it’s the same issue, why post in 3 separate threads?
The same issue, but new versions of Unity. I see it’s still unsolved. And probably will be.
It really does not help if the info is spread across different posts. Also it does not help if there is no project for the devs to look at. Even if your project is massive it’s pretty easy strip it down to smaller if the problem is related to code, ie. remove all art, sound files completely. If you think that would break it more then by the time you used to test and post all these things you could have written small script to that replaces all art, sounds etc with 1x1 pixel images, 0.1sec sounds and etc files
The devs did try to help you in both threads but it all stopped on you in both of em.
Yeah, I mean if it was my project, I would strip that project to the bones just to make sure it’s not one of my scripts or assets causing the problem. Neither you want to do it yourself, nor send the project to Unity. Do you think posting in a new thread will magically solve your problem?
If no one submits a usable bug report, it will most likely not be resolved.
Well, that is just plain Waste of time! you should use the elimination method as there really aren’t that many methods when detecting an error, especially when it’s about an asset! no matter how much you hate it, then there really aren’t that many methods! And the sooner you begin eliminating your assets & scripts the sooner you can continue Development on the game i know it sucks but there’s no way out!
And probably I will try eliminating my assets. In the beginning, I removed my scripts from my project because compilation is connected to scripts but… no change! Even without scripts I get the same compilation errors. Hell!!!
