添加到maven依賴項打包爲mar

Question

我有一個項目，它使用axis2項目中的多個依賴項。其中一個如果mex（metada交換）。

mex的最後一個版本被封裝爲mar文件。如果我嘗試添加這種依賴關係到我的項目Maven會失敗：

<dependency> 
     <groupId>org.apache.axis2</groupId> 
     <artifactId>mex</artifactId> 
     <version>1.6.1</version> 
     <packaging>mar</packaging> 

    </dependency>

我嘗試添加的插件損壞，但它沒有幫助

<plugin> 
      <groupId>org.apache.axis2</groupId> 
      <artifactId>axis2-mar-maven-plugin</artifactId> 
      <extensions>true</extensions> 
      <configuration> 
       <includeDependencies>false</includeDependencies> 
      </configuration> 
     </plugin> 

Answer 1

它看起來像你沒看過的錯誤消息正確的原因，它說：

Parse error reading POM. Reason: Unrecognised tag: 'packaging' (position: START_TAG seen ...</version>\n\t\t\t<packaging>... @229:15) for project unknown at /project/pom.xml 

這意味着你必須使用：

<dependency> 
    <groupId>org.apache.axis2</groupId> 
    <artifactId>mex</artifactId> 
    <version>1.6.1</version> 
    <type>mar</type> 
</dependency> 

改爲。

更新：問題是那些mar僞影被打包爲jar。所以，你必須去通過以下方式：

<dependency> 
    <groupId>org.apache.axis2</groupId> 
    <artifactId>mex</artifactId> 
    <version>1.6.1</version> 
</dependency>
