Scala Eclipse Compilation Issue:
scalatest_2.10-1.9.1.jar is cross-compiled with an incompatible version of Scala (2.10). In case of errorneous report, this check can be disabled in the compiler preference page.
Solution:
I feel The Issue is the Eclipse is Using the Library of Scala 2.10, But the eclipse Plugin is compiled of Scala 2.09.
I got resolved this issue By Downloading Eclipse Juno, and Installed Scala Pluggin, which is compatible with Eclipse.
The Version of Scala Plugin is 3.0.0.v-2_10
Hope it will Resolve your Issue.
