eclipse plugin does not build with 0.20.205 -------------------------------------------
Key: HADOOP-7726 URL: https://issues.apache.org/jira/browse/HADOOP-7726 Project: Hadoop Common Issue Type: Bug Components: contrib/eclipse-plugin 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. -- This message is automatically generated by JIRA.
