使用maven解包依赖和重新打包类?

我正在尝试解压缩maven工件A并将其重新打包到maven项目B中的新jar文件中。

将工件A中的类文件解压缩到:

    <my.classes.folder>${project.build.directory}/staging</my.classes.folder>

使用此工作正常:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>unpack</id>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>unpack</goal>
                    </goals>
                    <configuration>
                        <artifactItems>
                            <artifactItem>
                                <groupId>com.test</groupId>
                                <artifactId>mvn-sample</artifactId>
                                <version>1.0.0-SNAPSHOT</version>
                                <type>jar</type>
                                <overWrite>true</overWrite>
                                <outputDirectory>${my.classes.folder}</outputDirectory>
                                <includes>**/*.class,**/*.xml</includes>
                            </artifactItem>
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>

在同一个pom中,我现在想要生成一个包含刚刚解压缩的类的附加jar:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.4</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                    <configuration>
                    <classesdirectory>${my.classes.folder}</classesdirectory>
                        <classifier>sample</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin>

创建了一个新jar,但它不包含以下类:

 ${my.classes.folder}

它只是默认项目jar的副本。有什么想法吗?

我试图遵循本指南:

但它不起作用。

我建议你改用maven-shade-plugin

这将使unpack-repack在同一个调用中。

你可以这样做:

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.0</version>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <filters>
            <filter>
              <artifact>com.test:mvn-sample:1.0.0-SNAPSHOT</artifact>
              <includes>
                <include>**/*.class</include>
                <include>**/*.xml</include>
              </includes>
            </filter>
          </filters>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

在您拥有<classesdirectory>的示例中,docs的元素为<classesDirectory>。我认为区分大小写非常重要。
