can't compile the mapreduce project in eclipse

[Erix Yao <ya...@gmail.com>]

hi
   I checked out the source code from
http://svn.apache.org/repos/asf/hadoop/mapreduce/tags/release-0.21.0 and
execute ant compile eclipse-files , but after import the project into
eclipse, I found the error as below:

Description Resource Path Location Type
Project 'mapreduce' is missing required library:
'build/ivy/lib/Hadoop/common/avro-1.3.0.jar' mapreduce Build path Build Path
Problem

Description Resource Path Location Type
Project 'mapreduce' is missing required source folder:
'src/contrib/sqoop/src/java' mapreduce Build path Build Path Problem

missing dependency? missing source code?


can anybody here help me with that?

thanks

Did you add all dependencies of the source code?

Here, Avro jar is missing

And here, sqoop is missing. I don't why this library is required for 
this, but, it seems to be the problem.
You should add all the required dependencies on your CLASSPATH variables 
on Windows->Preferences->Java->Build Path->Classpath Variables

Please, go to the Cloudera Resources Site and you can search the 
Eclipse/Hadoop screencast that explains these details easy and quickly 
how to build the hadoop project.
