如何在maven- jar -plugin中使用jar:jar目标构建多个jar文件

Question

我们的pom.xml在maven- jar插件中有多个执行，目的是创建三个单独的jar文件。调用mvn并构建这三个jars的方法是什么？

目前

mvn compile jar:jar

仍然只创建一个罐子。

    <artifactId>maven-jar-plugin</artifactId>
        <version>2.3.2</version>
    <executions>
        <execution>
            <id>UDFCommon</id>
            <goals><goal>jar</goal></goals>
            <phase>package</phase>
            <configuration>
                <forceCreation>true</forceCreation>
                <classifier>UDFCommon</classifier>
                <includes>
                    <include>**/pafcommon/*</include>
                </includes>
            </configuration>
        </execution>
        <execution>
            <id>UDFOne</id>
            <goals><goal>jar</goal></goals>
            <phase>package</phase>
            <configuration>
                <classifier>UDFOne</classifier>
                <includes>
                    <include>**/dqm/*</include>
                </includes>
            </configuration>
        </execution>
        <execution>
            <id>UDFTwo</id>
            <goals><goal>jar</goal></goals>
            <phase>package</phase>
            <configuration>
                <classifier>UDFTwo</classifier>
                <includes>
                    <include>**/ciview/*</include>
                </includes>
            </configuration>
        </execution>
    </executions>
    </plugin>

Answer 1

jar:jar似乎不处理多个jar文件。但跑

mvn compile package

就能做到这一点。

-rw-r--r--   1 steve  staff    40315 Oct 16 15:24 UDFPafDqm-UDFOne.jar
-rw-r--r--   1 steve  staff     6942 Oct 16 15:24 UDFPafDqm-UDFCommon.jar

这需要一个assembly.xml :下面是一个基本的骨架。

<assembly>
    <id>job</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
            <directory>${project.build.outputDirectory}</directory>
            <outputDirectory>/</outputDirectory>
        </fileSet>
    </fileSets>


    <dependencySets>
        <dependencySet>
            <scope>runtime</scope>
            <outputDirectory>lib</outputDirectory>
        </dependencySet>
    </dependencySets>
</assembly>
