How to use local SNAPSHOT build in SBT

[Maarten Koopmans]

Hi,

In testing a ticket, I made a full build with mvn  of the branch with the fix. When I then ran sbt update, the jar was not copied from my maven repo, but downloaded from scala-tools.org (and as it was lift-webkit...)

So I ended up copying the jar to lib_managed myself to test it. But surely I am missing something...

Here's what my SBT project file looks like:

import sbt._

class LiftProject(info: ProjectInfo) extends DefaultWebProject(info) {

  val mavenLocal = "Local Maven Repository" at

  "file://"+Path.userHome+"/.m2/repository"

  val scalatools_snapshot = "Scala Tools Snapshot" at

  "http://scala-tools.org/repo-snapshots/"

  val scalatools_release = "Scala Tools Snapshot" at

  "http://scala-tools.org/repo-releasesi/"

  val liftVersion = "2.3-SNAPSHOT"

  // 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

  val mysql = "mysql" % "mysql-connector-java" % "5.1.12"

  override def libraryDependencies = Set(

    "net.liftweb" %% "lift-webkit" % liftVersion % "compile->default",

    "net.liftweb" %% "lift-mapper" % liftVersion % "compile->default",

  "net.liftweb" %% "lift-wizard" % liftVersion % "compile->default",

  "org.mortbay.jetty" % "jetty" % "6.1.22" % "test->default",

    "junit" % "junit" % "4.5" % "test->default",

    "ch.qos.logback" % "logback-classic" % "0.9.26",

    "org.scala-tools.testing" %% "specs" % "1.6.6" % "test->default",

    "com.h2database" % "h2" % "1.2.138"

  ) ++ super.libraryDependencies

}

Any thoughts? Then I can put this in a Wiki under "How to test fixes for tickets".

Got it: it's already in the build file as per the comments in the exampke I posted. Changing it to:

  val mavenLocal = "Local Maven Repository" at

  "file://"+Path.userHome+"/.m2/repository"

  // 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

  val liftVersion = "2.3-SNAPSHOT"

...worked like a charm...

Toss that on the wiki somewhere please.

Looks like uncommenting the scalatools snapshots repo line and making
sure the lift version is set to #.#-SNAPSHOT. At least that's how I've
used non-Lift artifact snapshots in the past.

Thanks, Chris

[Chris Reeves]

Oops, I misread. Here is the only difference that I see, but I have no
idea what it would actually accomplish.

val scalatoolsSnapshot = ScalaToolsSnapshots

Thanks, Chris

I'm not an SBT users (so I'm may be wrong).

From what I read (on the wiki), I think there is a confusion

If you enable the snapshot repository of scala-tools.org by
uncommenting

val scalatoolsSnapshot = ScalaToolsSnapshots

Then snapshots jar are toke from this repository, in this case it's
useless to git clone + build lift

If you want to use a locally compiled version of lift, you should
diseable (keep commenting) the snapshots repository of scala-tools.org
and enable your local maven repository (~/.m2/repository) where maven
install lift when you run "mvn clean install".

Good catch. What you need to do is also add this line to the to of you SBT project file:

 val mavenLocal = "Local Maven Repository" at

  "file://"+Path.userHome+"/.m2/repository"

But without the uncommenting, it wouldn't work for me. I am updating the wiki.

Hi Maarten,

If you want to use the snapshot version, there's no need to clone the repo and build it yourself. Every time a change is committed, Lift is automatically built and available in the Scala tools snapshot repo. All you need to do is add/uncomment the val scalatoolsSnapshot = ScalaToolsSnapshots line in your project file and change the version to 2.x-SNAPSHOT.

The only reason you would need to use the local repo is if you made changes yourself to Lift and wanted to use them.

Also, these 2 lines do the same thing:

 val scalatools_snapshot = "Scala Tools Snapshot" at

  "http://scala-tools.org/repo-snapshots/"

val scalatoolsSnapshot = ScalaToolsSnapshots

Just thought I'd mention that since they were both in your original post.

Hi Tim,

Thanks. But the wiki page is precisely about testing fixes on a not-commited branch. I ran int this initial set up thing when Derek asked me to test the fix for large uploads (or actually, all uploads), so I'd thought I'd share it. My goal was to make it easy for any developer to test a fix, so that part can be offloaded a bit from the core team.

Hi Maarten,

Sorry, I completely misread that.
