Problem running hive from eclipse

Hi,

I'm trying to launch junit test from eclipse, it fails with
ClassNotFoundException.

I did 'ant clean package eclipse-files' and imported the project into
eclipse, as specified in
https://cwiki.apache.org/Hive/gettingstarted-eclipsesetup.html.

When I run HIveCLI or TestCliDriver it says

Errors exist in required projects: hive
Proceed with launch?

When I proceed, it fails with

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/hive/cli/CliDriver

Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.hive.cli.CliDriver

at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at java.security.AccessController.doPrivileged(Native Method)

at java.net.URLClassLoader.findClass(URLClassLoader.java:190)

at java.lang.ClassLoader.loadClass(ClassLoader.java:306)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

Any help to come out this problem is much appreciated.

Environment :
OS : Mac OSX Lion 10.7.3
Java : 1.6.0.jdk

Thanks
Amareshwari

Hi, 

I don't know if this will help but I do a clean package separately and before running eclipse-files. This has always worked, but with a few quirks.

make sure you have correct jar files included in your eclipse application
launcher.
Try this:
Go to "Run Configuration" by right clicking on your project -> click "Run
As" -> Select "Run Configuration"
Select "TestCliDriver" JUNIT luncher->click on ClassPath tab-> make sure
all your jar files are there.
