package breeze as a jar

[Daniel Agota]

Hi,

I'm relatively new to both scala and breeze and wondered wether there is an easy way to include breeze
as an external jar in my eclipse project.

I have downloaded breeze (the zip), unpacked it and ran sbt with publish-local.
ran package too after it.

Now I'm stuck and sbt's walk through has not helped me either.

On my Linux under my user directory I have found the
.ivy2/local/default/default-f8dd8f_2.9.2/0.1-SNAPSHOT/jars
directory with some poms and other stuff, jars named default-f8dd8f_2.9.2.jar but that doeson't look like something I could include in my project...

I'm just looking for a good old jar ready to be added to my projects build path...without poms, maven deps, ivy etc.

Any advice or suggestion?

Thank you,
Daniel

You have two easy options.

Use sbteclipse: https://github.com/typesafehub/sbteclipse

OR

run sbt assembly

which will make a big jar in
learn/target/breeze/breeze-learn-0.1-SNAPSHOT-assembly.jar

that has all dependencies inside it.

Hi David,

thanks for the quick answer.

I have updated my plugins.sbt file according to the sbt-assembly getting started instructions, now it looks like:

resolvers += Resolver.url("artifactory", url("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases"))(Resolver.ivyStylePatterns)

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.7.2")

libraryDependencies ++= Seq(
  "org.jacoco" % "org.jacoco.core" % "0.5.6.201201232323" artifacts(Artifact("org.jacoco.core", "jar", "jar")),
  "org.jacoco" % "org.jacoco.report" % "0.5.6.201201232323" artifacts(Artifact("org.jacoco.report", "jar", "jar")))

addSbtPlugin("de.johoop" % "jacoco4sbt" % "1.2.2")

scalacOptions in Global += "-deprecation"

I have created a build.sbt in the project root directory (besides the sbt script ) with:

import AssemblyKeys._

jarName in assembly := "breeze.jar"

name := "breeze"

version := "1.0"

If I run assembly in the sbt command line I get an error stating:

[error] Not a valid command: assembly
[error] Not a valid project ID: assembly
[error] Not a valid configuration: assembly
[error] Not a valid key: assembly
[error] assembly
[error]         ^

Any hints maybe?

You have to make the assembly in breeze itself. It ships with the sbt
assembly plugin, so all you have to do is run sbt assembly in Breeze?

After some debugging I realized that the sbt pacman package I installed preaviously somehow interferred with the one packeged with breeze. After deleting it and starting the project new from download/unzip:

1 download and extract breeze zip
2 run ./sbt from command line
3 run assembly as an sbt command

your advice worked like charm.
Thank you, D

Great!
