Lift *DOES NOT* work on Scala 2.8 Beta1 RC4 & 5. Do not even try it. We are currently working with EPFL to resolve these issues.
Lift 1.1-M8 and Lift 1.1-SNAPSHOT only work with Scala 2.7.7. That is the *only* version of Scala that Lift 1.1-M8 and SNAPSHOT work with. If you have any other version of Scala specified in your pom.xml file, it will not work. Do not try to mix different versions of Lift in the same web app. The class loader will not know which versions of the Lift library go with different Servlets. Once you get your pom.xml file set up with Scala 2.7.7, then you must do a "mvn -U clean install" before doing an mvn jetty:run On Tue, Dec 22, 2009 at 7:39 PM, Alan M <[email protected]> wrote: > Update: > > I updated the other servlet to scala 2.8 and lift 1.1 snapshot (much > easier than I thought, I must be getting used to it) and I checked the > libs for both webapps and the commons lib directory.. no conflicting > versions of scala or lift jars..
