mvn install dependency:copy-dependencies 

工作为我在目标文件夹中创建的依赖目录。喜欢它!

你可以在你的项目目录中放置一个settings.xml文件，使用如下的基本配置:

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
    <localRepository>.m2/repository</localRepository>
    <interactiveMode/>
    <offline/>
    <pluginGroups/>
    <servers/>
    <mirrors/>
    <proxies/>
    <profiles/>
    <activeProfiles/>
</settings>

关于这些设置的更多信息可以在官方Maven文档中找到。 请注意，除非输入绝对路径，否则路径是相对于实际设置文件所在的目录进行解析的。

当你执行maven命令时，你可以像下面这样使用设置文件:

mvn -s settings.xml clean install

旁注:我在我的GitLab CI/CD管道中使用此功能，以便能够为几个作业缓存maven存储库，这样就不需要为每个作业执行下载依赖项。GitLab只能缓存项目目录中的文件或目录，因此我引用了项目目录中的一个目录。

这对我来说很管用:

<project>
  ...
  <profiles>
    <profile>
      <id>qa</id>
      <build>
        <plugins>
          <plugin>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
              <execution>
                <phase>install</phase>
                <goals>
                  <goal>copy-dependencies</goal>
                </goals>
                <configuration>
                  <outputDirectory>${project.build.directory}/lib</outputDirectory>
                </configuration>
              </execution>
            </executions>
          </plugin>
        </plugins>
      </build>
    </profile>
  </profiles>
</project>

假设

您不希望更改pom.xml 你不想要测试范围(例如junit.jar)或提供的依赖关系(例如wlfullclient.jar)

以下是对我有效的方法:

mvn install dependency:copy-dependencies -DincludeScope=runtime -DoutputDirectory=target/lib

最好的方法取决于你想做什么:

If you want to bundle your dependencies into a WAR or EAR file, then simply set the packaging type of your project to EAR or WAR. Maven will bundle the dependencies into the right location. If you want to create a JAR file that includes your code along with all your dependencies, then use the assembly plugin with the jar-with-dependencies descriptor. Maven will generate a complete JAR file with all your classes plus the classes from any dependencies. If you want to simply pull your dependencies into the target directory interactively, then use the dependency plugin to copy your files in. If you want to pull in the dependencies for some other type of processing, then you will probably need to generate your own plugin. There are APIs to get the list of dependencies, and their location on disk. You will have to take it from there...

看一看Maven依赖项插件，特别是依赖项:复制依赖项目标。查看标题为“依赖:复制依赖的魔咒”下的示例。将outputDirectory配置属性设置为${basedir}/target/lib(我相信，您必须进行测试)。

希望这能有所帮助。
