maven - 如何解决 Maven 中的未知 Artifact 类型 [test-jar] 错误？

Question

我在尝试使用 Maven 构建耳朵时遇到此错误。

问题:maven-ear-plugin 给出错误: [INFO] 无法初始化 Ear 模块嵌入错误:未知 Artifact 类型 [zip]

原因:传递依赖项中的 zip 或不受支持的文件

解决方案:在windows下，打开cmd，先cd你的项目根目录，然后在cmd中输入mvn dependency:tree，找到有传递依赖的与 marven-ear-plugin 冲突。

例如未知 zip +- com.sun.xml.ws:samples:zip:2.2.10:编译意思是

<groupId>com.sun.xml.ws</groupId>
<artifactId>samples</artifactId>

例如更改 Ear pom:将排除项放入您的依赖项中

<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-ri</artifactId>
... 
<exclusions>
<exclusion>     
<groupId>com.sun.xml.ws</groupId>       
<artifactId>samples</artifactId>          
</exclusion>          
... 
</exclusions>
</dependency>

与 +- com.sun.xml.ws:release-documentation:zip 相同
