Harsh J resolved HADOOP-7726.
-----------------------------
Resolution: Cannot Reproduce
(This has nothing to do with the eclipse-plugin)
No longer an issue on trunk/2.x branches. Please see
http://wiki.apache.org/hadoop/HowToContribute to import sources into eclipse.
> eclipse target does not build with 0.24.0
> -----------------------------------------
>
> Key: HADOOP-7726
> URL: https://issues.apache.org/jira/browse/HADOOP-7726
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 0.24.0
> Environment: Fedora 15
> Reporter: Tim Broberg
>
> I'm new to hadoop, java, and eclipse, so please forgive me if I jumble
> multiple issues together or mistake the symptoms of one problem for a
> separate issue.
> Attempting to follow the build instructions from
> http://wiki.apache.org/hadoop/EclipseEnvironment, the following commands are
> to be executed:
> 1 - mvn test -DskipTests
> 2 - mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true
> 3 - cd hdfs; ant compile eclipse
> 4 - cd ../; cd mapreduce; ant compile eclipse
> A - If "mvn test -DskipTests" is used for #1, #2 fails with "[ERROR] Failed
> to execute goal on project hadoop-yarn-common: Could not resolve dependencies
> for project org.apache.hadoop:hadoop-yarn-common:jar:0.24.0-SNAPSHOT:"
> Per Luke Lu's suggestion, "mvn install -DskipTests -P-cbuild" instead of step
> #1 cleared up this issue.
> B - For steps #3, and #4 there are no hdfs or mapreduce subdirectories. These
> appear to have been renamed "hadoop-hdfs-project" and
> "hadoop-mapreduce-project".
> C - For step #3, if I then go to hadoop-hdfs-project instead and perform "ant
> compile eclipse" no build.xml file is found - "Buildfile: build.xml does not
> exist!"
> D - For step #4, if I go to hadoop-mapreduce-project and do "ant compile
> eclipse" a set of errors much like #A is produced:
> > [ivy:resolve] ::::::::::::::::::::::::::::::::::::::::::::::
> > [ivy:resolve] :: UNRESOLVED DEPENDENCIES ::
> > [ivy:resolve] ::::::::::::::::::::::::::::::::::::::::::::::
> > [ivy:resolve] ::
> > org.apache.hadoop#hadoop-yarn-server-common;0.24.0-SNAPSHOT: not found
> > [ivy:resolve] ::
> > org.apache.hadoop#hadoop-mapreduce-client-core;0.24.0-SNAPSHOT: not found
> > [ivy:resolve] ::
> > org.apache.hadoop#hadoop-yarn-common;0.24.0-SNAPSHOT: not found
> > [ivy:resolve] ::::::::::::::::::::::::::::::::::::::::::::::
> E - If I ignore these issues and import the projects generated in step #2, I
> get a bunch of errors related to the lack of an M2_REPO definition. Adding
> this variable needs to be included in the build scripts or documentation in
> the wiki.
> F - Once that is resolved, eclipse shows hundreds of errors and warnings
> starting with "AvroRecord" cannot be resolved to a type.
> Thanks so much for your work on this, but it needs a little more effort in
> documentation and/or development before it is usable again.
> Thanks.
