Gradle / Bash - copy all env variables to app/gradle.properties (used to copy secret env vars from travis or circle CI to build android projects)

cp-env-to-properties.sh

#!/usr/bin/env bash
#
# Copy env variables to app module gradle properties file
#

set +x // dont print the next lines on run script
printenv | tr ' ' '\n' > app/gradle.properties
set -x

For those considering this solution, I found a much simpler alternative that works in some environments. Environment variables that start with "ORG_GRADLE_PROJECT_" are brought in as Gradle props!

@chriscm2006 This is a lot cleaner, thank you!

1. This doesn't require dynamically generating a gradle.properties file.
2. Only relevant variables (those prefixed with ORG_GRADLE_PROJECT_) are considered by Gradle, as opposed to printing all variables into gradle.properties.
