Cannot build a project without a local.properties file

Describe your issue

The Android Gradle plugin is capable of building a project with no local.properties file, as long as the ANDROID_HOME or ANDROID_SDK_ROOT environment variable is set. So the absence of this file should not be a fatal error:

java.io.FileNotFoundException: C:\Users\smith\cygwin\git\beeware\toga\examples\command\android\gradle\Command Example\local.properties (The system cannot find the file specified)
        at com.chaquo.python.PythonPlugin.createTicketTask(PythonPlugin.groovy:497)
        at com.chaquo.python.PythonPlugin$createTicketTask$9.callCurrent(Unknown Source)
