Cannot add task 'wrapper' as a task with that name already exists

android, expo, react-native, reactjs, wrapper

Solution

You can also update

task wrapper(type: Wrapper) {
    gradleVersion = '4.4'    
    distributionUrl = distributionUrl.replace("bin", "all")
}

to

wrapper {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

As

Overriding built-in tasks deprecated in 4.8 now produces an error.

Attempting to replace a built-in task will produce an error similar to the following:

Cannot add task 'wrapper' as a task with that name already exists.

see the last paragraph of Tasks & properties: https://docs.gradle.org/5.2.1/userguide/upgrading_version_4.html

and Customizing the Wrapper task: https://docs.gradle.org/5.2.1/userguide/gradle_wrapper.html#customizing_wrapper

Problem

When installing 'react-native init AwesomeProject' I get this error when I run `react-native run-android`: ``` Could not determine java version from '11.0.1'. ``` A quick google suggests I need to update the `distributionUrl` in the Gradle-wrapper. Having done this I am faced with a new error: ``` Cannot add task 'wrapper' as a task with that name already exists. ``` It suggests the issue is in the file: ``` /AwesomeProject/android/build.gradle' line: 36 ``` which looks like this ``` task wrapper(type: Wrapper) { gradleVersion = '4.4' distributionUrl = distributionUrl.replace("bin", "all") } ``` I've been back and forth trying to figure out what this does. It seems odd that something wouldn't work straight out of the box. Is anybody facing a similar issue?
