GAE (google apps engine) Lift Eclipse Setup

[Andreas]

Hi,

I have a working GAE Scala Eclipse setup based on:
http://penguinparens.blogspot.com/2009/04/further-steps-scalagwtapp-engineeclipse.html

How do I integrate the Lift framework from:
http://github.com/ymnk/liftweb/tree/master

thanks
Andreas

[David Pollak]

Not in direct answer to your question, but please use the main Lift distribution at http://github.com/dpp/liftweb/tree/master  No fork is officially supported and the latest fixes will be in the dpp/liftweb repository.
 

thanks
Andreas

This is my current setup:
1) Eclipse 3.5 with plugins: Scala, GAE
2) create a new GAE project without GWT
3) add Scala Nature to project and copy scala-library.jar to /war/WEB-
INF/lib
4) add this to .classpath:
<classpathentry kind="var" path="M2_REPO/net/liftweb/lift-mapper/1.0/
lift-mapper-1.0.jar" sourcepath="M2_REPO/net/liftweb/lift-mapper/1.0/
lift-mapper-1.0-sources.jar"/>
<classpathentry kind="var" path="M2_REPO/net/liftweb/lift-util/1.0/
lift-util-1.0.jar" sourcepath="M2_REPO/net/liftweb/lift-util/1.0/lift-
util-1.0-sources.jar"/>
<classpathentry kind="var" path="M2_REPO/net/liftweb/lift-webkit/1.0/
lift-webkit-1.0.jar" sourcepath="M2_REPO/net/liftweb/lift-webkit/1.0/
lift-webkit-1.0-sources.jar"/>
5) define project properties Java Build Path->Libaries->Add Variable
M2_REPO to maven repository on Mac OS X: /Users/ahe/.m2/repository
(repository needs to be filled with liftweb by creating on project
with maven on command line)
6) copy lift-mapper-1.0.jar, lift-util-1.0.jar, lift-webkit-1.0.jar
to /war/WEB-INF/lib
7) remove existing files in /src and add from default liftweb
structure the folder bootstrap and demo
8) copy from webapp/ templates-hidden and index.html to /war
9) replace from war/WEB-INF/web.xml with webapp/WEB-INF/web.xml

10) start Debug As -> Web Application

There are known issues with Lift 1.0 and GAE.

My understanding is that Lift 1.1-SNAPSHOT will work/may work on GAE.

Lift, the simply functional web framework http://liftweb.net

How do I compile the lift snapshot from the git repository?
Is there a maven config or wiki entry?

It's on the github wiki:

Hi, I followed this:

http://jpkutner.blogspot.com/2009/08/scala-and-lift-on-google-app-engine.html

then copied all the liftweb 1.1 and associated JARs into a GAE web
project WEB-INF/lib, and added them to the classpath, and the app
source files into src, (appropriately packaged). I found it all seemed
to launch and run fine but the scala code editor doesn't recognise the
imports to _root_.net.liftweb.... or give any code assistance to
things imported that way. Hover over reads "value net is not a member
of package <root>" The Java source editor has no problem with that
import (e.g. import net.liftweb.util.*;), and the Scala source editor
is fine with import _root_.scala.... its only the .net.liftweb it
can't seem to "find".

Any ideas?

New members are moderated.

Thanks Tyler, thought it might be something like that.

I can see that a more "conventional" approach of running mvn: eclipse
on the standard lift example project creates an eclipse project
without the problems mentioned above - so that gives me something to
go on to find what's up with my GAE project.

[alexda...@googlemail.com]

I found a fix for the errors on the importation at http://www.kleinfelter.com/node/82

You can run:
mvn -Declipse.workspace=K:\code eclipse:add-maven-repo

replacing K:\Code with your eclipse workspace. It sets elipse up to
search maven for references or somesuch.
