指定Maven的库目标

如何告诉Maven将依赖关系复制到特定的位置？

How can I tell Maven to copy the dependencies into a specific location?

侧面故事：我在Eclipse中有一个GWT项目，也是一个Maven模块一个更大的项目。这个GWT项目依赖于某些库，我需要将它们复制到< project-dir> / war / WEB-INF / lib 中。如何告诉Maven这样做？

Side story: I am having a GWT project in Eclipse that is also a Maven Module for a larger project. This GWT project has dependencies to some libraries and I need them to be copied into <project-dir>/war/WEB-INF/lib. How can I tell Maven to do that?

编辑：我找到了一种方式复制一个依赖关系 - 但是有没有办法用一个简单的指令复制所有这些？

Edit: I have found a way to copy a single dependency - but is there a way to copy all of them with a simple instruction?

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.10</version>
        <executions>
            <execution>
                <id>copy</id>
                <phase>package</phase>
                <goals>
                    <goal>copy</goal>
                </goals>
                <configuration>
                    <artifactItems>
                        <artifactItem>
                            <groupId>junit</groupId>
                            <artifactId>junit</artifactId>
                            <overWrite>false</overWrite>
                            <outputDirectory>${basedir}/war/WEB-INF/lib</outputDirectory>
                            <destFileName>optional-new-name.jar</destFileName>
                        </artifactItem>
                    </artifactItems>
                    <outputDirectory>${project.build.directory}/wars</outputDirectory>
                    <overWriteReleases>false</overWriteReleases>
                    <overWriteSnapshots>true</overWriteSnapshots>
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>  

我也尝试过：

</dependencies>

<build>
    <outputDirectory>${project.basedir}/war/WEB-INF/classes</outputDirectory>
    <plugins>
        <plugin>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <!-- up to <phase>deploy</phase> -->
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.basedir}/war/WEB-INF/lib</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>

</build>

结束一个错误说：

神器尚未打包。当在反应堆工件上使用时，应在打包后执行复制：请参阅MDEP-187。

Artifact has not been packaged yet. When used on reactor artifact, copy should be executed after packaging: see MDEP-187.
