复制特定工件

在复制特定工件时，您需要绑定依赖项：将mojo 复制到生命周期，配置插件并指定要复制的工件。请参见以下示例：

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
          <execution>
            <id>copy</id>
            <phase>package</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                  <groupId>junit</groupId>
                  <artifactId>junit</artifactId>
                  <version>3.8.1</version>
                  <type>jar</type>
                  <overWrite>false</overWrite>
                  <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
                  <destFileName>optional-new-name.jar</destFileName>
                </artifactItem>
              </artifactItems>
              <outputDirectory>${project.build.directory}/wars</outputDirectory>
              <overWriteReleases>false</overWriteReleases>
              <overWriteSnapshots>true</overWriteSnapshots>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

然后在执行mvn package之后，工件（junit）被复制到给定的alternateLocation。

如果需要， dependency:copy目标也可用于将刚刚构建的工件复制到自定义位置。它必须在安装阶段之后绑定，以便工件存在于存储库中。以下配置显示了如何：

 <project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
          <execution>
            <id>copy-installed</id>
            <phase>install</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                  <groupId>${project.groupId}</groupId>
                  <artifactId>${project.artifactId}</artifactId>
                  <version>${project.version}</version>
                  <type>${project.packaging}</type>
                </artifactItem>
              </artifactItems>
              <outputDirectory>some-other-place</outputDirectory>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

从命令行复制：

如果您打算将此 mojo 配置为在命令行上执行，请使用：

mvn dependency:copy

您不能将配置放在executions标签内。您的配置应如下所示：

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <configuration>
          <artifactItems>
            <artifactItem>
              <groupId>[ groupId ]</groupId>
              <artifactId>[ artifactId ]</artifactId>
              <version>[ version ]</version>
              <type>[ packaging ]</type>
              <overWrite>[ true or false ]</overWrite>
              <outputDirectory>[ output directory ]</outputDirectory>
              <destFileName>[ filename ]</destFileName>
            </artifactItem>
          </artifactItems>
          <!-- other configurations here -->
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>
