Sample Name

(i.e. Gmail Quickstart)
google classroom quickstart (java)

###context
Was following instructions in https://developers.google.com/classroom/quickstart/java, however the program would fail to build in step 2.

Expected Behavior

when running:

gradle init --type basic

and

mkdir -p src/main/java src/main/resources

and

gradle run

expected program to build and then run and create token file

Actual Behavior

Build failed; due to 'build.gradle.kts' not being the correct file type. When I renamed it to simply be 'build.gradle', Quickstart would build and run correctly.

Specifications
