Maven Archetype Plugin

發博詞

經測試，Maven Archetype Plugin這個插件非常好使；用這個插件去處理一個符合Maven最佳實踐的項目，會得到一個非常好的結果；

User Guide

mvn archetype:create-from-project

在項目根子產品下面執行mvn archetype:create-from-project指令，會生成一個maven archetype項目。再此項目下執行maven install，會将此archetype安裝到本地maven倉庫；

mvn archetype:generate -DarchetypeCatalog=local

使用此指令按照提示操作，可以使用剛剛安裝到本地的maven倉庫的archetype建立一個項目；

Notice

1. 生成的項目的各個Module的artifactId都帶着groupId字首
2. Maven插件對package的處理過程，将現有項目的包名去掉groupid,不會比對去掉artificialid

常用變量

1. ${groupId}：groupid；
2. ${artifactId}：目前子產品的artifactId，每個子產品一個，來自目前子產品的配置資訊，看archetype-metadata小節
3. ${rootArtifactId}：根子產品的artifactId
4. ${parentArtifactId}：父子產品的 artifactId，子產品劃分多層級的時候會用到
5. ${version}

archetype-metadata
