Hi, I’m following the instructions from [google](https://developers.google.com/sheets/api/quickstart/java) to build a Java application that can read/write to Google Sheets. when I run  
`gradle -q run`  
I get this:

Error: Could not find or load main class Quickstart

FAILURE: Build failed with an exception.

- What went wrong:  
Execution failed for task ‘:run’.  
\> Process ‘command ‘C:\Program Files\Java\jdk1.8.0\_162\bin\java.exe’’ finished with non-zero exit value 1

more detailed info [here](https://scans.gradle.com/s/twvfnlduocgcc/)

What did I do wrong?

Are you sure you followed Step 3 (`Create a file named src/main/java/Quickstart.java`) exactly as written? The `mainClassName` in Step 2 must match the name of the class exactly, so if you created a `src/main/java/QuickStart.java` or anything that doesn’t match exactly, the main class will not be found.

I have the same problem and had it previously working yesterday. When I tried it today I had the same error + permission errors.
