openjdk-helper

This is a simple service meant to help with OpenJDK project activities. It is being used by my OpenJDK Project Assistant Custom GPT.

Using the openjdk-helper

The openjdk helper is up and running at https://api.hirt.se/openjdk/version. It is available and ready to use.

The api is described here:
https://api.hirt.se/openjdk/swagger-ui/

Or in openapi format here:
https://api.hirt.se/openjdk/openapi/

Running the application in dev mode

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

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory.
Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.jar.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Dnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Dnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/openjdk-helper-(version)-SNAPSHOT-runner

Creating the docker image

You can create a docker image using:

mvnw clean package -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true

To create one with a native image:

mvnw clean package -Pnative -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true

Run the image using:

docker run -i --rm -p 8080:8080 greystone/openjdk-helper:latest

Publishing images (for maintainers)

To create docker images for multiple platforms and push them to Docker hub:

./release.sh
