I just want to build a project (new Unity version 2018.3.3f1) but I get the following error. What is wrong here? OK, I found out that the build-tools are not actually on the file system. Now, I can play the game, but when I want to build an APK I get loads of "compile errors". How can that be? They come from the Animancer plugin.
i got this error too (from Unity2017.4.17) On Mac build apk always failed, my build tool had updated to 28.0.3 now i dowegrade to Unity2017.4.14
The error says "SDK Build Tools". You have the sdk platform tools 28 installed, but not the build tools. Installing the latest build tools should fix this error.
