試験管のなかのコード :: Maven2 で POM の inheritance & aggregation を整理してみる(3)

Maven2 で POM の inheritance & aggregation を整理してみる(3)

inheritance & aggregation の実験

inheritance & aggregation 用のサンプルプロジェクトは下記の様な構成。基本的には前回 2 つと全く同じ。 \both\pom.xml は packageing=pom で aggregation を使用できるようにしてある。 \both\child\pom.xml は継承を表す parent タグを使用して \both\pom.xml を継承してある。

\both
　　├pom.xml
　　└child
　　　　├pom.xml
　　　　└src
　　　　　　└java
　　　　　　　　└com
　　　　　　　　　└example
　　　　　　　　　　　└HelloWorld.java

\both\pom.xml

artifactId、name 以外は aggregation のサンプルと全く同一。

<project>

  <parent>
    <groupId>com.example</groupId>
    <artifactId>pom-both-sample</artifactId>

  <artifactId>pom-both-sample-child</artifactId>
  <name>pom both sample - child</name>
  <packaging>jar</packaging>

</project>

\both で Maven2 による compile を実行した結果

aggregation を使用しているので、\both\pom.xml を使用してコンパイルを実行すると \both\child\pom.xml も同時に処理されている。また、inheritance も使用しているので、\both\pom.xml の設定項目が \both\child\pom.xml に継承されている。

\both\child で Maven2 による compile を実行した結果

\both\child\pom.xml を使用してコンパイルを実行してみる。 \both\pom.xml を継承しているので、\both\child\pom.xml がきちんと \both\pom.xml の内容を引き継いでいることが分かる。
