Hi, I'm following the steps suggested by the wiki page:
EclipseEnvironment - Hadoop Wiki (http://wiki.apache.org/hadoop/EclipseEnvironment) in order to have an Eclipse project for Hadoop. I'm exactly trying to execute the following command: mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true But I always get the following error: [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 12.657s [INFO] Finished at: Tue Oct 04 02:04:11 BRT 2011 [INFO] Final Memory: 31M/282M [INFO] ------------------------------------------------------------------------ [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: Failed to collect dependencies for [log4j:log4j:jar:1.2.12 (compile), org.apache.hadoop:hadoop-yarn-api:jar:0.24.0-SNAPSHOT (compile), org.apache.avro:avro:jar:1.5.3 (compile), com.google.protobuf:protobuf-java:jar:2.4.0a (compile), org.apache.hadoop:hadoop-common:jar:0.24.0-SNAPSHOT (compile), org.apache.hadoop:hadoop-annotations:jar:0.24.0-SNAPSHOT (compile), junit:junit:jar:4.8.2 (compile), org.mockito:mockito-all:jar:1.8.5 (test), org.apache.hadoop:hadoop-common:jar:tests:0.24.0-SNAPSHOT (test), org.apache.hadoop:hadoop-hdfs:jar:0.24.0-SNAPSHOT (runtime), com.google.inject.extensions:guice-servlet:jar:2.0 (compile), org.jboss.netty:netty:jar:3.2.3.Final (compile), org.slf4j:slf4j-api:jar:1.6.1 (compile), org.slf4j:slf4j-log4j12:jar:1.6.1 (compile)]: Failed to read artifact descriptor for org.apache.hadoop:hadoop-yarn-api:jar:0.24.0-SNAPSHOT: Failure to find org.apache.hadoop:hadoop-yarn:pom:${yarn.version} in http://repository.jboss.org/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of repository.jboss.org has elapsed or updates are forced -> [Help 1] Then, I try mvn -X eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true and get [DEBUG] ======================================================================= [INFO] [INFO] >>> maven-eclipse-plugin:2.8:eclipse (default-cli) @ hadoop-yarn-common >>> [DEBUG] Could not find metadata org.apache.hadoop:hadoop-yarn-api:0.24.0-SNAPSHOT/maven-metadata.xml in local (/home/assis/.m2/repository) [DEBUG] Using connector WagonRepositoryConnector with priority 0 for http://repository.apache.org/snapshots Downloading: http://repository.apache.org/snapshots/org/apache/hadoop/hadoop-yarn-api/0.24.0-SNAPSHOT/maven-metadata.xml Downloaded: http://repository.apache.org/snapshots/org/apache/hadoop/hadoop-yarn-api/0.24.0-SNAPSHOT/maven-metadata.xml (785 B at 1.0 KB/sec) [DEBUG] Reading resolution tracking file /home/assis/.m2/repository/org/apache/hadoop/hadoop-yarn-api/0.24.0-SNAPSHOT/resolver-status.properties [DEBUG] Writing resolution tracking file /home/assis/.m2/repository/org/apache/hadoop/hadoop-yarn-api/0.24.0-SNAPSHOT/resolver-status.properties [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] Apache Hadoop Project POM .........................

So, I download it myself, try again, and the same things happen. Can anyone help me, please? I'm using Ubuntu 11.04 with jdk1.7.0, maven 3.0.3 and protobuf 2.4.1. Thanks in advance! Alexandre A. B.
