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.
