# Maven-hello

- maven で 他jarに依存するプログラムを書く。

- executable な fatJARを作る。

もとは

```bash

mvn -B archetype:generate \

-DarchetypeArtifactId=maven-archetype-quickstart \

-DinteractiveMode=false \

-DarchetypeVersion=1.4 \

-DgroupId=com.sample \

-DartifactId=hello

```

で作って、POMを一生懸命修正したもの。

JAVAとmavenのバージョンは以下の通り。

```

$ java -version

openjdk version "11.0.16" 2022-07-19

OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu122.04)

OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

$ javac -version

javac 11.0.16

$ mvn -version

Apache Maven 3.6.3

Maven home: /usr/share/maven

Java version: 11.0.16, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64

Default locale: ja_JP, platform encoding: UTF-8

OS name: "linux", version: "5.15.0-1020-aws", arch: "amd64", family: "unix"

```

# compile & run

```bash

mvn compile

mvn exec:java

```

# pakcage & run

```bash

mvn package

# maven-shade-plugin で executable な fatJAR ができる

java -jar target/hello-1.0-SNAPSHOT.jar

```

# tips

maven-shade-plugin を pluginManagement の子として書かないこと。

書くと `mvn package` で処理してくれない。
