Hi Jyoti, Thanks for the help. I tried your steps, while trying "mvn compile" I get build failure message with these two warnings: [INFO] ------------------------------------------------------------------------ [INFO] Building Apache Giraph Examples 1.1.0-SNAPSHOT [INFO] ------------------------------------------------------------------------ [WARNING] The POM for org.apache.giraph:giraph-core:jar:1.1.0-SNAPSHOT is missing, no dependency information available [WARNING] The POM for org.apache.giraph:giraph-core:jar:tests:1.1.0-SNAPSHOT is missing, no dependency information available [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------
and this error message: [ERROR] Failed to execute goal on project giraph-examples: Could not resolve dependencies for project org.apache.giraph:giraph-examples:jar:1.1.0-SNAPSHOT: The following artifacts could not be resolved: org.apache.giraph:giraph-core:jar:1.1.0-SNAPSHOT, org.apache.giraph:giraph-core:jar:tests:1.1.0-SNAPSHOT: Failure to find org.apache.giraph:giraph-core:jar:1.1.0-SNAPSHOT in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1] I dont know much of maven, tried google-ing, but it didn't help.
