Question

我有一个maven项目，我说Spring框架库作为依赖项，我想将Spring框架依赖项与传递依赖项复制到指定的位置。

我已经浏览过apache的maven依赖插件指南，我有几个选项，其中没有它们将解决完整的问题。

复制依赖项选项

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.8</version>
        <executions>
          <execution>
            <id>copy-dependencies</id>
            <phase>package</phase>
            <goals>
              <goal>copy-dependencies</goal>
            </goals>
            <configuration>
              <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
              <overWriteReleases>false</overWriteReleases>
              <overWriteSnapshots>false</overWriteSnapshots>
              <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
          </execution>
        </executions>
      </plugin>

这会将所有依赖项和传递复制到给定位置，我只想要Spring依赖项和传递。

复制特定工件

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.8</version>
        <executions>
          <execution>
            <id>copy</id>
            <phase>package</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                   <groupId>org.springframework</groupId>
                   <artifactId>spring-web</artifactId>
                   <version>3.2.4.RELEASE</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>

这不是应对传递依赖。

解决我的两个问题的任何解决方案。

Answer 1

程序集插件可以做到这一点。

插件配置：

     <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>3.1.0</version>
            <configuration>
                <descriptors>
                    <descriptor>src/assembly/assembly.xml</descriptor>
                </descriptors>
                <finalName>plugins</finalName> <!--folder name in target directory-->
            </configuration>

            <executions>
                <execution>
                    <id>some-id</id> <!-- must match assembly id in assembly.xml-->
                    <phase>pre-integration-test</phase> <!-- pic -->
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>

        </plugin>

assembly.xml

<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">

    <id>some-id</id>
    <formats>
        <format>dir</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>

    <dependencySets>
        <dependencySet>
            <includes>
                <include>
                    org.springframework:spring-web
                </include>
            </includes>
            <useTransitiveDependencies>true</useTransitiveDependencies>
            <useTransitiveFiltering>true</useTransitiveFiltering>
        </dependencySet>
    </dependencySets>

</assembly>

重要的位是<useTransitiveDependencies>true</useTransitiveDependencies>和<useTransitiveFiltering>true</useTransitiveFiltering>，这导致include应用于项目依赖项，而不应用于传递性依赖项，从而导致 spring-web工件和它是依赖项，将其复制到目录中。

Answer 2

您可以使用maven程序集插件。

检查出来，特别是依赖集：

http://maven.apache.org/plugins/maven-assembly-plugin/

http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html#class_dependencySet

您可以提供输出目录，并可以指定要放在哪个依赖项

还有一个选项：useTransitiveDependencies。将此设置为true可获得所需的行为。

Answer 3

这是一个选项：

创建模块（生产者）以收集依赖关系并将其作为zip发布。
：解压缩解压缩

这很麻烦，排除仍然需要一些樱桃采摘，但更少，它可以在并行线程中运行。
