如何從罐子中真正完全排除包裝？

Question

具有這種依賴關係部分中我的pom.xml：

<dependencies> 
    <dependency> 
    <groupId>junit</groupId> 
    <artifactId>junit</artifactId> 
    <version>3.8.1</version> 
    <scope>test</scope> 
    </dependency> 


    <dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-rt-frontend-jaxws</artifactId> 
    <version>2.7.1</version> 
    <type>jar</type> 
    <scope>runtime</scope> 
    </dependency> 
    <dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-rt-transports-http</artifactId> 
    <version>2.7.1</version> 
    <type>jar</type> 
    <scope>runtime</scope> 
    </dependency> 
    <dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-web</artifactId> 
    <version>3.0.7.RELEASE</version> 
    </dependency> 


    <dependency> 
    <groupId>mysql</groupId> 
    <artifactId>mysql-connector-java</artifactId> 
    <version>5.1.26</version> 
    </dependency> 
    <dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>4.2.6.Final</version> 
    </dependency> 
    <dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-api</artifactId> 
    <version>2.7.1</version> 
    <exclusions> 
     <exclusion> 
     <groupId>org.apache.geronimo.specs</groupId> 
     <artifactId>geronimo-javamail_1.4_spec</artifactId> 
     </exclusion> 
    </exclusions> 
    </dependency> 
    <dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-rt-transports-http</artifactId> 
    <version>2.7.1</version> 
    <type>jar</type> 
    </dependency> 

    <dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>servlet-api</artifactId> 
    <version>2.5</version> 
    </dependency> 

    <dependency> 
    <groupId>javax.mail</groupId> 
    <artifactId>mail</artifactId> 
    <version>1.4.1</version> 
    </dependency> 
    <dependency> 
    <groupId>javax.activation</groupId> 
    <artifactId>activation</artifactId> 
    <version>1.1.1</version> 
    </dependency> 

</dependencies> 

我預期從構建排除Geronimo的javamail_1.4_spec包，事實上，當我運行mvn dependency:tree，它是沒有在那裏更長時間。

但是，在運行所產生的罐子時，則仍的JarClassLoader抱怨由Geronimo的那些被隱藏的javax /郵件類...

果然，當我檢查通過7-ZIP的罐子，我看到geronimo-javamail_1.4_spec-1.7.1.jar仍然存在（作爲org.apache.cxf的一部分：cxf-api：jar：2.7.1：compile package）。

如何完全排除軟件包？即不僅將它從依賴關係樹中移除，而且還不包括它在所產生的jar中？

添加每下面的評論中onejar相關的XML：

<plugin> 
    <groupId>com.jolira</groupId> 
    <artifactId>onejar-maven-plugin</artifactId> 
    <version>1.4.4</version> 
    <executions> 
    <execution> 
     <configuration> 
     <mainClass>com.corp.dept.proj.myclient</mainClass> 
     <onejarVersion>0.97</onejarVersion> 
     <attachToBuild>true</attachToBuild> 
     <!-- Optional, default is "onejar" --> 
     <classifier>onejar</classifier> 
     </configuration> 
     <goals> 
     <goal>one-jar</goal> 
     </goals> 
    </execution> 
    </executions> 
</plugin>

Answer 1

onejar插件添加了maven運行時範圍內的所有工件，因爲它應該是。

命令mvn dependency:tree似乎沒有正確列出所有運行時依賴關係。可能是一個錯誤，我不知道爲什麼。

幸運的是，通過添加一些參數，您可以列出所有運行時作用域依賴關係。

mvn dependency:tree -Dscope=runtime -Ddebug=true 

這將顯示cxf-rt-core也有geronimo-javamail的依賴。所以，你的解決方案是明確地將核心jar與排除在你的依賴關係之外。

<dependency> 
     <groupId>org.apache.cxf</groupId> 
     <artifactId>cxf-rt-core</artifactId> 
     <version>2.7.1</version> 
     <exclusions> 
      <exclusion> 
       <groupId>org.apache.geronimo.specs</groupId> 
       <artifactId>geronimo-javamail_1.4_spec</artifactId> 
      </exclusion> 
     </exclusions> 
    </dependency>
