An optional path, relative to the build's workspace, to the generated dSYM.zip (iOS and MacOS) or mapping.txt (Android) file.
You can include build variables here like ${BUILD_NUMBER}
and they'll be expanded at build time.
e.g. "MyApp/build/Beta-iphoneos/MyApp-Beta-${BUILD_NUMBER}.dsym.zip if your use ${BUILD_NUMBER} as technical version number (CFBundleShortVersionString).
Can use wildcards like 'module/dist/**/*.dSYM.zip'.
See the @includes of Ant fileset for the exact format.
