Android Studio Where is the Compiler Error Output Window

Question

When I 'Run' my project in Android Studio, in the 'Messages' window, I receive the line:

Gradle: 
FAILURE: Build failed with an exception. 

* What went wrong: 
Execution failed for task ':play01:compileDebug'. 
> Compilation failed; see the compiler error output for details. 

* Try: Run with --stacktrace option to get the stack trace. 
Run with --info or --debug option to get more log output.

It also says > Compilation failed; see the compiler error output for details. So where is the "compiler error output" and how do I run it with --stacktrace option?

Answer 1

While using Android Studio 3.1, please select the icon below the Build one in the Build window.

By Android Studio 3.3 also possibly in 3.2.1, the icon has changed, however the location is the same:

The build window should open when you run a build action for instance in the build menu. If you don't see it, you can try the "Build" button along the bottom of the window which is visible in the above screenshots or alternatively through the menus View → Tool Windows → Build.
