• suspend して debugger 待ち

mvn clean compile quarkus:dev -DskipTests -Dsuspend=true

• container で native build も簡単

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

• できている native image に対してテスト

./mvnw test-compile failsafe:integration-test

Logging

quarkus.log.level=INFO
quarkus.log.category."org.hibernate".level=DEBUG

quarkus-maven-plugin

• GenerateCodeMojo (mvn debug 18787) QuarkusBootstrap -> CuratedApplication -> QuarkusClassLoader

  CodeGenerator -> List = []

• DevMojo (mvn debug 18787)

  DevModeRunner

  debug port

  DevModeRunner.run() -> java.lang.ProcessBuilder -> java.lang.ProcessImpl.start()

  DevMojo.execute() loop : check pom.xml changes

live reload (hot swap)

• RuntimeUpdatesProcessor (quarkus 5005)

  VertxHttpHotReplacementSetup -> RuntimeUpdatesProcessor.doScan() -> restart = true ->

                    if (restart) {
                        routingContext.request().headers().set(HEADER_NAME, "true");
                        VertxHttpRecorder.getRootHandler().handle(routingContext.request());
                    }
