1.将maven依赖的jar导出到一个目录中:
mvn dependency:copy-dependencies
maven项目所依赖的jar包会默认导出到targed/dependency目录中
也可以设置输出的目录,依赖级别,通常用compile级别,如下:
mvn dependency:copy-dependencies -DoutputDirectory=/yourDir -DincludeScope=compile
2.查找某个jar包的依赖
mvn dependency:tree -Dverbose -Dincludes=groupId:artifactId
例如:查找log4j
mvn dependency:tree -Dverbose -Dincludes=org.slf4j:log4j
