Can anyone help me or tell me I'm doing wrong

Thank you very much for your attention

[Diego Medina]

I sometimes see the NoClassDefFoundError error when I have a mix of
scala versions in the classpath, or if my project has the same
library, but two different versions.

So, a few questions:
1- Are you using dispatch? if you do, and you use json, you need to
tell sbt (or maven, etc), not to pull lift-json from dispatch, like:

"net.databinder" %% "dispatch-lift-json" % "0.8.5" intransitive(),

Or:
2- try doing sbt clean, sbt compile
3- how are you moving your project to a mac? you git clone your repo
and build it?, are you compiling your war on one machine and deploying
it to anther machine?

Hopefully that would do, if not, just reply to this message and we'll
figure out what's going on.

Thanks

Diego

in linux, which I was a tar.gz of the project

decompressed in the Mac and compile the project again

in the browser still displays the same :(

[Diego Medina]

hm, ok,

Just in case, did you run clean and update after you changed the
dispatch dependency?

could you include your build.sbt file?


Thanks

[Sanx]

Hi

Yes :(



I have no file build.sbt

but I have the following files:


LiftProject.scala

import sbt._

class LiftProject(info: ProjectInfo) extends DefaultWebProject(info) {
val liftVersion = property[Version]

// uncomment the following if you want to use the snapshot repo
// val scalatoolsSnapshot = ScalaToolsSnapshots

// If you're using JRebel for Lift development, uncomment
// this line
// override def scanDirectories = Nil

lazy val JavaNet = "Java.net Maven2 Repository" at "http://
download.java.net/maven/2/"

override def libraryDependencies = Set(
"net.liftweb" %% "lift-webkit" % liftVersion.value.toString %
"compile",
"net.liftweb" %% "lift-mapper" % liftVersion.value.toString %
"compile",

"junit" % "junit" % "4.7" % "test",

) ++ super.libraryDependencies

}

and build.properties


#Project properties

[Diego Medina]

"net.liftweb" % "lift-widgets_2.8.1" % "2.4",

is the problem

you are using sala 2.9.0-1 for all dependencies, but then lift-widget
is bringing in 2.8.1

change that line to


"net.liftweb" %% "lift-widgets" % "2.4",


and all should be good


Thanks

Diego

[Olek Swirski]

you might want to use jetty 8, if so, the line below does the job:
"org.eclipse.jetty" % "jetty-webapp" % "8.1.0.v20120127" % "test, container"
when using some jetty specific configurations you may need to add:
"org.eclipse.jetty" % "jetty-plus" % "8.1.0.v20120127" % "test, container"

[Diego Medina]

jetty 8 will not work because Sanx is using sbt 0.7.x , and it does
not support jetty other than 6.x

[Olek Swirski]

ups :) btw anyone tried new sbt 0.12 already?

[Sanx]

OK

Wow! you are right, problem solved

thank you all for your help!

Cool!

[Naftoli Gugenheim]

I have. Also the lift build has actually been using a beta of 0.12.
