gradle-download-task | 📥 Adds a download task | Plugin library

In order for Gradle to discover task dependencies, they have to use specific types for their inputs and outputs so that Gradle can track the dependencies for you. See this documentation page on the topic.

In your use case, the de.undercouch.download plugin seems to expose a simple List which is not a rich type, so Gradle cannot figure out the link. In that case you have be explicit about the task dependency, using dependsOn(downloadZipFile)

Depending on how you have created your react-native project with Expo will determine what folders are available and how you install dependencies.

By default Expo abstracts away the native iOS and Android code so that you do not have to worry about it.

As you project does not have and ios and android folders, this means that you are using a managed workflow which means you cannot install dependencies that add native code.

Expo provides MapView which is what you are looking for. You can install it by following the instructions here.

Basically, as you are using a managed workflow, you should use:

You're right, the problem is due to the very old Gradle version used in the releases/1.12 branch of that repo.

The version of Gradle used by the gradlew command is determined by the file gradle/wrapper/gradle-wrapper.properties. If you edit that file and change the distributionUrl property to use gradle-4.4-all.zip (like in develop branch of this repo) instead of gradle-2.0-all.zip, you should be able to at least build the project.
