This is your new Kotlin Android Project! Happy hacking!
- Create a new template project.
- Choose a LICENSE.
- Set your
ORG_GRADLE_PROJECT_NEXUS_USERNAME
,ORG_GRADLE_PROJECT_NEXUS_PASSWORD
,ORG_GRADLE_PROJECT_SIGNING_KEY
andORG_GRADLE_PROJECT_SIGNING_PWD
secrets in Settings. - Code some cool apps and libraries 🚀.
- 100% Kotlin-only template.
- 4 Sample modules (Android app, Android library, Kotlin library, Jetpack Compose Activity).
- Jetpack Compose setup ready to use.
- Sample Espresso, Instrumentation & JUnit tests.
- 100% Gradle Kotlin DSL setup.
- CI Setup with GitHub Actions.
- Publish to Maven Central with Github Actions.
- Dependency versions managed via
buildSrc
. - Kotlin Static Analysis via
detekt
andktlint
. - Issues Template (bug report + feature request).
- Pull Request Template.
This template is using Gradle Kotlin DSL as well as the Plugin DSL to setup the build.
Dependencies are centralized inside the Gradle Version Catalog in the libs.versions.toml file in the gradle
folder.
This template is using detekt to analyze the source code, with the configuration that is stored in the detekt.yml file (the file has been generated with the detektGenerateConfig
task). It also uses the detekt-formatting plugin which includes the ktlint rules (see https://detekt.dev/docs/rules/formatting/).
This template is using GitHub Actions as CI. You don't need to setup any external service and you should have a running CI once you start using this template.
There are currently the following workflows available:
- Validate Gradle Wrapper - Will check that the gradle wrapper has a valid checksum
- Pre Merge Checks - Will run the
build
,check
andpublishToMavenLocal
tasks. - Publish Snapshot - Will publish a
-SNAPSHOT
of the libraries to Sonatype. - Publish Release - Will publish a new release version of the libraries to Maven Central on tag pushes.
The template is setup to be ready to publish a library/artifact on a Maven Repository.
For every module you want to publish you simply have to add the publish
plugin:
plugins {
publish
}
In order to use this template to publish on Maven Central, you need to configure some secrets on your repository:
Secret name | Value |
---|---|
ORG_GRADLE_PROJECT_NEXUS_USERNAME |
The username you use to access Sonatype's services (such as Nexus and Jira) |
ORG_GRADLE_PROJECT_NEXUS_PASSWORD |
The password you use to access Sonatype's services (such as Nexus and Jira) |
ORG_GRADLE_PROJECT_SIGNING_KEY |
The GPG Private key to sign your artifacts. You can obtain it with gpg --armor --export-secret-keys <[email protected]> or you can create one key online on pgpkeygen.com. The key starts with a -----BEGIN PGP PRIVATE KEY BLOCK----- . |
ORG_GRADLE_PROJECT_SIGNING_PWD |
The passphrase to unlock your private key (you picked it when creating the key). |
The template already sets up Dokka for project documentation and attaches -sources.jar
to your publications,
via the new AGP publishing DSL.
Once set up, the following workflows will take care of publishing:
- Publish Snapshot - To publish
-SNAPSHOT
versions to Sonatype. The workflow is setup to run either manually (withworkflow_dispatch
) or on every merge. - Publish Release - Will publish a new release version of the libraries to Maven Central on tag pushes. You can trigger the workflow also manually if needed.
If you're using JitPack, you don't need any further configuration and you can just configure the repo on JitPack.
You probably want to disable the [Publish Snapshot] and Publish Release workflows (delete the files), as Jitpack will take care of that for you.
The project includes three sub-projects, each in their own subdirectories:
app
: The source for the final Android application.library-android
: The source for an Android library including UI.library-kotlin
: The source for a UI-less Kotlin library.library-compose
: The source for a UI library with Jetpack Compose library.
The following additional top-level directories configure & support building the app & projects:
buildSrc
: Contains shared Gradle logic as precompiled script pluginsconfig
: Contains the Detekt configuration file.gradle
: Contains Gradle Configuration files such as the Gradle Version Catalog and the Gradle Wrapper.
Finally, the following hidden top-level directories provide functionality for specific development systems:
.github
: Defines the Github Actions CI tasks and templates for new pull requests, issues, etc..idea
: Sets common initial project settings when the project is opened in Android Studio or IntelliJ IDEA.
Feel free to open a issue or submit a pull request for any bugs/improvements.
