Upgrading an old project to Gradle 6 and AGP 3.5.3

[jmfayard]

I have been trying to upgrade projects to Gradle 6

A procedure that seems reliable:

• ./gradlew wrapper --gradle-version 5.6.3
• build.gradle: upgrade "com.android.tools.build:gradle:3.5.3"
• run ./gradlew tasks
• run ./gradlew assembleDebug
• ./gradlew wrapper --gradle-version 6.1.1
• add build scan
• add bootstrap for the project
• add plugin

Plugin setup

Settings file

// settings.gradle.kts

import static de.fayard.versions.PluginsManagementSetupKt.setupVersionPlaceholdersResolving
buildscript {
    dependencies.classpath("de.fayard.refreshVersions:de.fayard.refreshVersions.gradle.plugin:0.8.6")
}
setupVersionPlaceholdersResolving(settings)

Root Build file

// build.gradle
buildscript {
}
plugins {
  id("de.fayard.refreshVersions")
}

app/build.gradle

plugins {
  id("de.fayard.dependencies") version "0.5.1"
}
