Subject [Hadoop Wiki] Update of "GitAndHadoop" by SteveLoughran
Date Mon, 07 Dec 2009 12:15:16 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "GitAndHadoop" page has been changed by SteveLoughran.
http://wiki.apache.org/hadoop/GitAndHadoop?action=diff&rev1=2&rev2=3

--------------------------------------------------

  
  This Ant target not only builds the JAR files, it copies it to the local {{{${user.home}/.m2}}}
directory, where it will be picked up by the "internal" resolver. You can check that this
is taking place by running {{{ant ivy-report}}} on a project and seeing where it gets its
dependencies.
  
+ If there are problems, don't be afraid to {{rm -rf ~/.m2/repository/org/apache/hadoop}}
 and {{rm -rf ~/.ivy2/cache/org.apache.hadoop}} to remove local copies of artifacts.
+ 
  === Testing ===
  
  Each project comes with lots of tests; run {{{ant test}}} to run them. If you have made
changes to the build and tests fail, it may be that the tests never worked on your machine.
Build and test the unmodified source first. Then keep an eye on both the main source and any
branch you make. A good way to do this is to give a Continuous Integration server such as
Hudson this job: checking out, building and testing both branches.
