maven只编译指定的module？

Question

比如我要编译spark源码，用这个指令

build/mvn -Phadoop-2.6 -Dhadoop.version=2.6.0 -DskipTests clean package

spark有很多module，我想一次只编译其中几个module可以吗？

Answer 1

mvn -DskipTests clean package -pl sql/catalyst,sql/core,sql/hive
-pl,--projects <arg>                   Comma-delimited list of specified
                                        reactor projects to build instead
                                        of all projects. A project can be
                                        specified by [groupId]:artifactId
                                        or by its relative path
