Buildpack Builder config example

Example of a java project able to build a Quarkus, Spring Boot, ... project using the DSL BuildConfig.builder()

To use it, configure the following mandatory environment variables pointing to a project (example: hello-quarkus, hello-spring) to be built as a container image

export PROJECT_PATH=<JAVA_PROJECT>
# <IMAGE_REF> can be <IMAGE_NAME> without registry or a full registry reference with host, port(optional), path & tag
export IMAGE_REF=<IMAGE_REF> 

If you plan to push your image to a registry, then set your registry credential using these variables:

export REGISTRY_USERNAME="<REGISTRY_USERNAME>"
export REGISTRY_PASSWORD="<REGISTRY_PASSWORD>"
export REGISTRY_ADDRESS="docker.io"

If you prefer that lifecycle don't access the mounted docker socket but talk directly with the container registry to build the image, then set to false the following variable:

export USE_DAEMON=false

Execute this command in a terminal:

mvn compile exec:java

You can also pass the BP_ or CNB_ environment variables:

export BP_JVM_VERSION="21"
export BP_MAVEN_BUILT_ARTIFACT="target/quarkus-app/lib/ target/quarkus-app/*.jar target/quarkus-app/app/ target/quarkus-app/quarkus"
export CNB_LOG_LEVEL=debug
etc
