I have tried in all these ways

• ./sbt (in bin directory of breeze) and then update -> compile -> publish-local -> console
• scala -cp <ivy path to jars>
• scala
• scala> :cp <path to each jar>

I was in bin directory and executing ./sbt instead of executing bin/sbt in the breeze directory. Now, it's working. thanks a lot
