Specifies filenames or patterns matching one or more ProGuard mapping
files that should be uploaded to Google Play, so that it can automatically
deobfuscate stacktraces from crash reports.
You can use wildcards like "**/build/**/mapping.txt".
See
the 'includes' attribute of Ant's FileSet for the exact format.
Note that multiple entries must be comma-separated.
The base directory is the build's workspace.
You can only upload mapping files that are located in your workspace.
If there are multiple APKs being uploaded, and only one
mapping.txt file is found, then this file will be associated
with each of the APKs being uploaded. If there are multiple
mapping.txt files, this plugin will make a basic attempt to
associate each mapping file with the corresponding APK.
Otherwise, if the number of mapping files found is not equal to the
number of APKs being uploaded, the build will fail, as this situation
is not supported.
For more information on deobfuscating crash stacktraces, see the
Google Play documentation:

This field supports substituting environment variables in the form
${SOME_VARIABLE} or $SOME_VARIABLE at build time.
