典型场景:apache
1.须要某个特殊的 jar包,可是有不能直接经过maven依赖获取,或者说在其余环境的maven仓库内不存在,那么如何将咱们所须要的jar包打入咱们的生产jar包中。maven
2.某个jar包内部包含的文件是咱们所须要的,或者是咱们但愿将它提取出来放入指定的位置 ,那么除了复制粘贴,如何经过maven插件实现呢?测试
dependency插件咱们最经常使用到的是ui
dependency:copy url
dependency:copy-dependencies:Goal that copies the project dependencies from the repository to a defined location. spa
dependency:unpack .net
dependency:unpack-dependencies 这四个插件
若是要实现上述的两种场景,咱们须要的 是 第一个和第三个。code
copy
样例:将两个指定的jar包junit slf4j-log4j12 分别输出到${project.build.directory}/lib/lib1 目录下 即${project.basedir}/target/lib 目录下。
