Hello, thank you for your support..I am almost there.. But I after lots of
googling I see that I have
"decorates Java projects and working sets that contain build path errors".
I see a red exclamatory sign on all the projects in the package explorer.
One possible solution I tried is to try JRE System Library -> Alternate
JRE. It was originally set to JRE System Library[JavaSE-1.6].
I also tried the Workspace default JRE(java-7-oracle).
I tried to delete all the messaged in the Problem tab, and clean the
project but it still remained.
I tried to maventest on the mahout-math project individually by right
clicking on mahout-math and selecting run as -> maventest.
It gives
Results :
Tests run: 1867, Failures: 0, Errors: 0, Skipped: 0
[INFO]
------------------------------------------------------------------------
[INFO] BUILD SUCCESS

[INFO] Finished at: Wed Nov 28 01:57:27 CET 2012
[INFO] Final Memory: 15M/132M
[INFO]
I tried to delete the messages in the Problem tab, and then clean the
project. but the problem still remained.
I guess I again need help to sort this issue.
The message in the Problem tab is:
A cycle was detected in the build path of project 'mahout-math'. The cycle
consists of projects {mahout-core, mahout-math, mahout-examples,
mahout-integration}
The project cannot be built until build path errors are resolved
And so on for the rest of the projects.
