== migrate from maven to gradle (heroku only)
.install heroku cli, register (if has no account) and login
[source,bash]
----
brew install heroku
heroku login
----
.clone my heroku maven (java buildpack) example project which has already ptrepared gradle stuff
[source,yml]
----
git clone https://github.com/daggerok/heroku-java-buildpack-example.git
rm -rf .git .mvn mvnw* pom.xml heroku.yml
----
.add requred heroku-gradle setup
[source,yml]
----
echo "task stage(dependsOn: 'build')" >> build.gradle
----
.create heroku app and deploy to it with development profile
[source,yml]
----
git init .
heroku create daggerok-gradle-buildpack
echo "web: SPRING_PROFILES_ACTIVE=dev ./build/libs/*.jar" > Procfile
git add .
git commit -am "First blood!"
git push heroku master
heroku logs -t
# find output: The following profiles are active: dev,spring-boot,data-jpa
----
key points here (if you just create app from scratch):
- you need prepare gradle `stage` task for build
echo "task stage(dependsOn: 'build')" >> build.gradle
- you need prepare Procfile with bash application startup command (in out case it's: `./build/libs/*.jar`)
echo "web: SPRING_PROFILES_ACTIVE=dev ./build/libs/*.jar" > Procfile
- you need install gradle wrapper in your project
gradle wrapper
git add -f gradle*
git commit -am "Add gradle wrapper"
== going production
.for production (heroku) version add postgres database
[source,bash]
----
heroku addons:create heroku-postgresql:hobby-dev
----
.now let's configure correct heroku URL and switch spring-boot app to production prpofile which is using postgres database:
[source,bash]
----
echo "web: SPRING_PROFILES_ACTIVE=prod APP_BASE_URL=https://daggerok-gradle-buildpack.herokuapp.com ./build/libs/*.jar" > Procfile
git add .
git commit -am "Setup right heroku application environment variables"
git push heroku master
----
.just FYI
[source,bash]
----
heroku git:remote -a daggerok-gradle-buildpack
git remote -v
