如何在Maven中获得依赖关系的artificactId？

Question

我有多模块项目。依赖关系如下：

<dependencies>              
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-commons</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-places-module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-devices-module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-events-module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-controls-module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.gwr</groupId>
        <artifactId>gwr-logs-module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
</dependencies>

而且，在每个模块/依赖项的src/main/resources下，我有一个名为<module>-persistence.zip (例如C:\gwr-logs-module\src\main\resources\logs-persistence.zip)的ZIP文件。我想将每个模块的ZIP文件复制到其他目录下，比如C:\users\user\project。我将maven-resources-plugin定义如下：

<plugin>
    <artifactId>maven-resources-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-presubscriptionfiles</id>
            <phase>validate</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${user.home}/${dasmo.storage}/</outputDirectory>
                <overwrite>true</overwrite>
                <resources>
                    <resource>
                        <directory>${basedir}/../gwr-logs-module/src/main/resources</directory>
                        <includes>
                            <include>*.zip</include>
                        </includes>
                    </resource>
                    <resource>
                        <directory>${basedir}/../gwr-devices-module/src/main/resources</directory>
                        <includes>
                            <include>*.zip</include>
                        </includes>
                    </resource>
                    <resource>
                        <directory>${basedir}/../gwr-controls-module/src/main/resources</directory>
                        <includes>
                            <include>*.zip</include>
                        </includes>
                    </resource>
                    <resource>
                        <directory>${basedir}/../gwr-events-module/src/main/resources</directory>
                        <includes>
                            <include>*.zip</include>
                        </includes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

正如您所看到的，在资源部分，我必须对每个模块名进行硬编码。我怎么才能避免这种情况？我们不能使用每个依赖项的artifactId吗？如果是，如何使用？或者还有其他方法来做这份工作？

非常感谢。你好啊，叶什维德

您可以将多模块POM中的<plugin>部分简化为以下内容：

<plugin>
  <artifactId>maven-resources-plugin</artifactId>
  <executions>
    <execution>
      <id>copy-presubscriptionfiles</id>
      <!-- Note: this phase is more appropriate than 'validate' -->
      <phase>process-resources</phase>
      <goals>
        <goal>copy-resources</goal>
      </goals>
      <configuration>
        <outputDirectory>${user.home}/${dasmo.storage}</outputDirectory>
        <overwrite>true</overwrite>
        <resources>
          <resource>
            <directory>${project.basedir}/src/main/resources</directory> 
            <!-- or likewise
            <directory>${project.projectDirectory}/src/main/resources</directory>
            -->
            <includes>
              <include>*.zip</include>
            </includes>
          </resource>
        </resources>
      </configuration>
    </execution>
  </executions>
</plugin>

如果您在任何子模块POMs中将您的多模块项目声明为<parent>，这将由它们继承(请参阅POM简介，项目继承)，并在每个子模块构建时执行。

注意:反对basedir而赞成project.basedir.
