Using eclipse hotdeploy

From Lift

this is out of date

create a new project from lift-archetype-blank (or from an other archetype):

mvn archetype:generate -U                                     \
 -DarchetypeGroupId=net.liftweb                             \
 -DarchetypeArtifactId=lift-archetype-blank                 \
 -DarchetypeVersion=0.9                            \
 -DremoteRepositories=http://scala-tools.org/repo-releases  \
 -DgroupId=your.proj.gid -DartifactId=your-proj-id

set eclipse configuration:

mvn eclipse:eclipse

compile src and test

mvn test

Eclipse needs to know the path to the local maven repository. Therefore the classpath variable M2_REPO has to be set. Execute the following command:

mvn -Declipse.workspace=<path-to-eclipse-workspace> eclipse:add-maven-repo

start eclipse

import project : File>Import...>Existing project into workspace

right click on your-proj-id > src/test/scala > RunWebApp.scala and select Debug As > Open Debug Dialog...

check that the value of "Scala application object" is RunWebApp (there is a bug in some version scala plugin about the location of the class when you right click and run directly (the first time), also, be sure it's not set to src.test.scala.RunWebApp.)

click on Debug

in the console you should see something like
