After upgrade from Upsource 2.0 to 3.0 it started to do code analysis on Java source files. Now it results in thousands of errors like:
Cannot resolve symbol 'String'
Cannot resolve symbol 'java'
Cannot resolve symbol 'com'
...
We do not need code analysis at all. How to disable it? I cannot find this option in the UI.
Go to project's settings, find "Upsource properties", and set the "Build System" to "None". This'll turn it off. However it seems that it's just doing it wrong.
