Time Keeper project

This project uses Quarkus 1.1.1, the Supersonic Subatomic Java Framework. If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

You can have a look at this project and use it as a simple tutorial, if you want to evaluate Quarkus.

List of Quarkus features

For Lunatech employees only

A full documentation about this Lunatech project is avalaible on Lunatech Confluence web site

Database with Docker

First we will need a PostgreSQL database; you can launch one easily if you have Docker installed:

eval $(docker-machine env default)

then

docker run --ulimit memlock=-1:-1 -it --rm=true --memory-swappiness=0 --name timekeeper-db -e POSTGRES_USER=quarkus_test -e POSTGRES_PASSWORD=quarkus_test -e POSTGRES_DB=timekeeper -p 5434:5432 postgres:10.5

Alternatively you can setup a PostgreSQL instance in any another way.

The connection properties of the Agroal datasource are configured in the standard Quarkus configuration file, which you will find in src/main/resources/application.properties.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw quarkus:dev

Packaging and running the application

The application is packageable using ./mvnw package. It produces the executable timekeeper-1.0.0-SNAPSHOT-runner.jar file in /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

The application is now runnable using java -jar target/timekeeper-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

If GraalVM is configured on your server, you can create a native executable using: ./mvnw package -Pnative.

Or you can use Docker to build the native executable using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your binary: ./target/timekeeper-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image-guide .

Tips

If you want to add a new Quarkus extension :

./mvnw quarkus:add-extension -Dextensions="openapi"

GraalVM on Mac OS

  • Go to https://github.com/oracle/graal/releases
  • Download version 19.2 here
  • unzip
  • move the graalvm-ce-19.2.1 folder to /Library/Java/JavaVirtualMachines
  • use /usr/libexec/java_home -V to show a list of JVM
  • use /usr/libexec/java_home -v 1.8.0_231 to set the JVM to GraalVM

You can also use jenv utility.

jenv add /Library/Java/JavaVirtualMachines/graalvm-ce-19.2.1/Contents/Home

Check that Graal VM is configured

> nicolas:quarkus-timekeeper-demo nmartignole$ jenv local 1.8.0.232
> nicolas:quarkus-timekeeper-demo nmartignole$ jenv local
1.8.0.232
> nicolas:quarkus-timekeeper-demo nmartignole$ java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-20191009173705.graal.jdk8u-src-tar-gz-b07)
OpenJDK 64-Bit GraalVM CE 19.2.1 (build 25.232-b07-jvmci-19.2-b03, mixed mode)

You should then be able to install 'native-image'

gu install native-image
