Lift Eclipse Project

[Andy Czerwonka]

Hello Lift-ers,

Can anyone point me to a resource that'll help me setup my Eclipse
Scala-IDE environment for a Lift Project? I taken the latest
lift_21_sbt project from GitHub as a starting point.

[Vlad Seryakov]

Check https://www.assembla.com/wiki/show/liftweb/ for articles about
Eclipse, also
check http://www.scala-ide.org/

[Andy Czerwonka]

Thanks. I found https://www.assembla.com/wiki/show/liftweb/Using_Lift_in_Eclipse_and_terminal_without_MVN_SBT
but I guess my version of the Scala-IDE doesn't work at all. I
installed it on the latest Helios (clean) and File->New->Acala
Application doesn't even work. I can't open any Scala files - I get
a:

Could not initialize class
scala.tools.eclipse.ScalaSourceViewerConfigurationUtils$

Oh well - I should probably just use a text editor as I've always had
trouble with the Eclipse Scala IDE - it's never really worked for me.

In the 4 years I've been doing Scala work, the Eclipse Scala plugin has never worked reliably. :-(

I use it daily (with trouble sometimes (wrong error)) : Eclipse
3.5/3.6 + scala-ide (for the right version of eclipse see
http://download.scala-ide.org) + M2eclipse + m2eclipse-scala + JRebel
you need to :
* increase memory settings (in eclipse.ini)
* enable JDT weaving (in preferences) after scala-ide installation
* create or import your project under eclipse (you should be able to
create from maven archetype if you use m2eclipse familly plugins)
* create a launcher to run src/test/scala/RunWebApp

Could you send the error (from error view) ?

The sample project you use is SBT based, so I can't help more (I don't use SBT).

The last error I have (compiler error) is in LiftConsole. It can't
find _root_.scala.tools.nsc.MainGenericRunner. I'm guessing that's
some kind of compiler hook?

Do you have scala-compiler in as dependencies.
FYI LiftConsole is not made to be run from eclipse but from a shell
(jline, arrows key don't work into a eclipse's console)

[Andy Czerwonka]

What is everyone using out there? Do I have to go back to Emacs? I
could use TextMate at home, but I was hoping to share the
configuration with my Windowz machine at the office. :-( And with
Apple deprecating Java.... :-(

I currently use IntelliJ with the Scala plugin. I first gave Eclipse and Netbeans a try - did not work out for me. It seems IntelliJ is most suitable for Scala programming if you prefer to work with a full blown IDE.

[Andy Czerwonka]

Are you working with Lift?

[Florian Heinisch]

Yes, I use IntelliJ for a Lift project.

It's pretty straight forward: Just use one of the Maven archetypes to create a Lift project and import this project into IntelliJ.
Just in case you are not familiar with IntelliJ, this article describes how to in detail:
http://blog.morroni.com/2010/07/14/setup-intellij-9-for-lift-framework-development/comment-page-1/

If you prefer SBT have a look at Heiko's article about Scala with SBT and IntelliJ:

When I run your example, it works great. If I try and change the
archetype to something more recent, say lift-archetype-basic_2.8.0 and
2.2-M1 as the version, there is no run menu available when I import
the project.

Note: I posted this message on the blog

[Andy Czerwonka]

This is what I created:

mvn archetype:generate -U \
-DarchetypeGroupId=net.liftweb \
-DarchetypeArtifactId=lift-archetype-basic_2.8.0 \
-DarchetypeVersion=2.2-M1 \
-DremoteRepositories=http://scala-tools.org/repo-releases
\
-Dversion=0.1 \
-DgroupId=com.andyczerwonka.test -DartifactId=test

No run menu option in IntelliJ plus no incremental compilation.

[Florian Heinisch]

For the case, your run button is greyed out, there are two ways in IntelliJ to run "mvn jetty:run":
1. On the very right side of the IDE there is a small bar with vertical buttons - hit the "Maven Projects" button. You should see your maven project there, just expand the root tree node, then "Plugins", then "jetty" and double click "jetty:run"
2. In the menu bar -> Run -> Edit Configurations -> click the + button left on top -> Maven. In the textfield "Working directory" paste the absolute path to your project (the directory that contains the pom.xml), in the textfield "Goals" paste jetty:run.

By incremental compilation you mean that IntelliJ does not display errors in your Scala source code upon typing (which I cannot reproduce) or that IntelliJ does not compile the class when you save the file?
For the latter case: IntelliJ does not autocompile files such as Eclipse does (however it saves the file you edit automatically). If you want to have autocompilation as in Eclipse have a look here:
http://www.jetbrains.com/idea/documentation/migration_from_netbeans_faq.html#Can_I_enable_compile_on_save_in_IntelliJ_IDEA
Or you simply remap the default shortcut for compilation Shift+F9 (Shift+Command+F9 on the Mac) to CRTL+S (or Command+S) in File -> Settings -> Keymap

Hope this helps!

IntelliJ does not display errors as I type and it does not compile the
class as I save it either. I'll try the "Eclipse-mode" plug-in, but I
was assuming IntelliJ would highlight errors.

[Andy Czerwonka]

Looks like 'Eclipse Mode' is broken....

[Florian Heinisch]

IntelliJ definitely should highlight errors, works perfectly for me.
Did you install IntelliJ's Scala plugin? Which version of IntelliJ do you use?

[Florian Heinisch]

Sorry - I do not use this plugin, so I did not know it is apparently not working for recent versions (just saw comments on the plugin site that state it does not work for IntelliJ version 9.03 and 9.04).

[Andy Czerwonka]

I'm going with TextMate and SBT for now. I spent the whole weekend
trying to get things to work and have not succeeded. I do want
refactoring, so I'll try IntelliJ again if things start working with
IntelliJ 9.0.4.
