I'm new to Flutter and trying to run the example project when you create a new one. When trying to run it, I have this issue:
FAILURE: Build failed with an exception.
Where: Build file 'PROJECTPATH/android/app/build.gradle' line: 25
What went wrong: A problem occurred evaluating project ':app'.
Could not resolve all files for configuration 'classpath'. Could not find lint-gradle-api.jar (com.android.tools.lint:lint-gradle-api:26.1.2). Searched in the following locations: https://jcenter.bintray.com/com/android/tools/lint/lint-gradle-api/26.1.2/lint-gradle-api-26.1.2.jar
I understand it's trying to get the file "lint-gradle-api-26.1.2.jar" from the jcenter repository but when following the link I get this:
{
"errors" : [ {
"status" : 404,
"message" : "Could not find resource"
} ]
}
So I added the Google repository in my build.gradle
file:
buildscript {
repositories {
maven { url 'https://dl.google.com/' }
google()
jcenter()
}
...and I also succeed to get the file by following this link:
...but I'm still getting the same error when trying to run my project, whether it is by using Visual Studio Code, Android Studio or with the CLI.
How do I force Gradle to download the file from the link I've found?
Here's how my build.gradle
file looks like:
buildscript {
repositories {
//maven { url 'https://dl.google.com/dl/android/maven2/com/android/tools/lint/lint-gradle-api/26.1.2/lint-gradle-api-26.1.2.jar' }
repositories {
google()
maven { url 'https://maven.fabric.io/public' }
mavenCentral()
jcenter()
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
}
}
allprojects {
repositories {
google()
maven { url 'https://maven.fabric.io/public' }
mavenCentral()
jcenter()
}
}
repositories {
google()
maven { url 'https://maven.fabric.io/public' }
mavenCentral()
jcenter()
}
....
I solved the problem by moving:
maven {
url 'https://dl.google.com/dl/android/maven2'
}
in the top of:
jcenter()
in the file: .flutter/packages/flutter_tools/gradle/flutter.gradle
:
buildscript {
repositories {
maven {
url 'https://dl.google.com/dl/android/maven2'
}
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
}
}
