網上的文章太坑,自己記錄下解決war專案依賴的要點:

1.warpath 是個坑,按照網上的說明基本跑不通,可能是maven-war-plugin 升級了不相容,不建議再去使用warpath了,maven-war-plugin就可以搞定所有的事情了

2.dependency type war 就可以實現war包依賴,B依賴A,打包的時候就會把A的classes以及檔案打進去

<dependency>
<groupId>com.handlecode</groupId>
<artifactId>diy-biz</artifactId>
<version>${diy.version}</version>
<type>war</type>
</dependency>

3.如果B要使用A內的類,則需要新增類依賴

<dependency>
<groupId>com.handlecode</groupId>
<artifactId>diy-biz</artifactId>
<version>${diy.version}</version>
<type>jar</type>
<classifier>classes</classifier>
<scope>provided</scope>
</dependency>

在A的外掛配置內也要配置 <attachClasses>true</attachClasses>,這樣B專案內就可以使用A專案定義的class了,scope指定provided,打包的時候就不會把***-classes帶入lib內

4.打包的時候如果不想使用WEB-INF/classes,則在外掛的配置內指定 <archiveClasses>true</archiveClasses> 即可,這樣會把專案的java檔案打包成jar放到WEB-INF/lib內

一個完整的示例B依賴A:
