Simple applicaiton workflow:

you can find front-end gui here: https://github.com/nmajorov/expenses-web-ui

This project uses Quarkus, the Supersonic Subatomic Java Framework.

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 can be packaged using ./mvnw package. It produces the code-with-quarkus-1.0.0-SNAPSHOT-runner.jar file in the /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/code-with-quarkus-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

At the moment it's only working with madrel or graalvm version 21.3!!!

You can create a native executable using: ./mvnw package -Pnative.

Or, if you don't have GraalVM installed, you can run the native executable build in a container using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your native executable with: ./target/code-with-quarkus-1.0.0-SNAPSHOT-runner

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

OpenShift pipelines troubleshooting

Sometimes database migration get problem with old schema files especially after OpenShift update.

Run this statement:

DROP SCHEMA IF EXISTS expenses CASCADE;
