Hello! I am using the following procedure to build hadoop from sources:
First, run mvn -Dmaven.repo.local=/path/to/m2 to populate /path/to/m2 directory with required artifacts; Then I always run mvn -Dmaven.repo.local=/path/to/m2 --offline so it does not download anything during the build. It worked fine with versions 2.4.1 and 2.6.0. But with 2.7.1 I get the following error: <...> [INFO] Apache Hadoop Distribution [INFO] [INFO] ------------------------------------------------------------------------ [INFO] Building Apache Hadoop Main 2.7.1 [INFO] ------------------------------------------------------------------------ [WARNING] The POM for org.apache.maven.plugins:maven-clean-plugin:jar:2.4.1 is missing, no dependency information available [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] Apache Hadoop Main ................................
