備註:需要3.5.3以上版本
可用mvn --version指令查看目前版本

RHEL更新Maven方式：
https://computingforgeeks.com/installing-latest-apache-maven-on-centos-fedora/
需先sudo yum remove maven


(2)
git clone https://github.com/redhat-developer-demos/quarkus-tutorial.git

cd quarkus-tutorial

(4)
export TUTORIAL_HOME='pwd'
export QUARKUS_VERSION=0.21.2

(5)
mvn "io.quarkus:quarkus-maven-plugin:$QUARKUS_VERSION:create" \
  -DprojectGroupId="com.example" \
  -DprojectArtifactId="fruits-app" \
  -DprojectVersion="1.0-SNAPSHOT" \
  -DclassName="FruitResource" \
  -Dpath="fruit"

(6)
確認檔案已產生
cd fruits-app
ls -al

(7)
已開發模式啟動(具備Hot Reload功能)
./mvnw compile quarkus:dev

=======以下是改用Native模式編譯
(9)
oc new-project quarkustutorial

(10)
編譯成native executable(需安裝GraalVM)
./mvnw package -DskipTests -Pnative

Windows平台編譯問題請參考以下文章
https://quarkus.io/guides/building-native-image#producing-a-native-executable

如果沒安裝GraalVM，使用container runtime(預設是使用docker，可用下方指令指定)
./mvnw package -DskipTests -Pnative -Dquarkus.native.container-build=true
https://quarkus.io/guides/building-native-image#quarkus-native-pkg-native-config_quarkus.native.container-build

https://quarkus.io/guides/building-native-image
By default Quarkus automatically detects the container runtime. If you want to explicitely select the container runtime, you can do it with:
# Docker
./mvnw package -Pnative -Dquarkus.native.container-build=true -Dquarkus.native.container-runtime=docker

# Podman
./mvnw package -Pnative -Dquarkus.native.container-build=true -Dquarkus.native.container-runtime=podman
