Implementation for scala 2.11

[pdolega]

What's wrong with this project working on 2.11 ? We finalized two projects with bluesprints-scala on Scala 2.11.6 + Java 8.

What are the problems you encounter with this setup ?

Builds are passing with all the tests on Scala 2.11 and Java 7 / Java 8:

This the error I am getting trying to run blueprints-scala with OrientDB . I assumed it is due that fact the ScalaObject is deprecated since version 2.10.0. I've read this post on StackOverFlow http://stackoverflow.com/questions/7781547/noclassdeffounderror-scala-scalaobject-in-mixed-scala-java-project and when I check my project's "External Libraries" (Intellij) I have SBT: org.scala-lang:scala-library:2.11.7:jar included. So I am not sure where I am going wrong here.

This is the code I am trying to run

implicit val db = new OrientGraphFactory(uri).setupPool(1, 10).getTx()
case class Person(name: String, kind: String)
val hercules = Person("hercules", "demigod")
db.save(hercules)

You pulled wrong version of blueprints scala in this line:

...
"com.ansvia.graph" % "blueprints-scala_2.10" % "0.1.41",
...

Just use:

...
"com.ansvia.graph" %% "blueprints-scala" % "0.1.61",
...

Now - just after pressing "Comment" I realized that problem may be different (I did quick check which seems to confirm my suspicion).

While we do have releases and Travis builds for Scala 2.11.x we may not have these artifacts published to Maven Central. For me it wasn't a problem since we have our own Jenkins job which at the end published blueprints-scala artifacts to our company's Nexus.

@anvie is it possible that you are not publishing 2.11 artifacts to Maven Central ? (I couldn't find any). By the way is this process automated (e.g. via Travis builds) ? @janm399 wrote nice blog post about that here - we should be able to automate whole thing if it's done manually.

@pdolega you are right! I was using the wrong version. Just so that I don't have to wait for the latest artifacts to be available on Maven central I have built the project locally and published it to my local ivy repository to use in my project. Hopefully the latest artifacts will be published to Maven soon.

Thanks heaps.

@simerplaha cool, good to hear that it works for you now.
@anvie let me know what do you think about releasing artifacts from Travis. It should be possible to do that without exposing your Sonatype credentials (as described here)

[anvie]

@pdolega cool, i dunno if that possible, thx for pointer, I will made changes soon when I have a time.
Looks like @simerplaha problem has been solved, closed.
