For example, if Application “FOO” version “1” is installed onto a pool, the environment variable is AZ_BATCH_APP_PACKAGE_FOO_1. AZ_BATCH_APP_PACKAGE_FOO_1 points to the location that the package was downloaded (a folder). When using the default version of the app package, use the AZ_BATCH_APP_PACKAGE environment variable without the version numbers. | Any task with an associated app package.
