You need JDK 15 to compile and run this project and you also need to enable preview mode since record are used. Right now enabling preview mode for compiling and dev mode works out of the box, not need to do anthing specific.
But for some test and some more advanced build processing you might need to set this ENV variable.
export _JAVA_OPTIONS="--enable-preview"
Configured with JIB, will push directly to docker hub
./mvnw clean package -Dmaven.test.skip=true -Dquarkus.container-image.push=true
Place the .env file with ENV variables you want to override in the root folder (together with pom.xml).
When you compile mvn clean quarkus:dev this is added to target folder automatically.
Note that all ENV settings should be upper cased. Use underscores to replace any . and - symbols.
A simple .env file can look like the one below, see the file env example file for a more detailed example.
