Re: Flink-ML as Dependency

Hi Max,

I think the reason is that the flink-ml pom contains as a dependency an artifact with artifactId breeze_${scala.binary.version}. The variable scala.binary.version is defined in the parent pom and not substituted when flink-ml is installed. Therefore gradle tries to find a dependency with the name breeze_${scala.binary.version}.

I try to find a solution for this problem. As a quick work around you should be able to define the variable manually and set it to 2.10.

Cheers,
Till

Hi Flinksters,

I would like to test FlinkML. Unfortunately, I get an error when including it to my project. It might be my error as I'm not experienced with Gradle, but with Google I got any wiser.

My build.gradle looks as follows:

apply plugin: 'java'
apply plugin: 'scala'

//sourceCompatibility = 1.5
version = '1.0'
jar {
    manifest {
        attributes 'Implementation-Title': 'Test Project',
                   'Implementation-Version': 1.0
    }
}

repositories {
  mavenCentral()
  mavenLocal()
}

dependencies {
  compile 'org.scala-lang:scala-library:2.10.5'
  compile 'org.scala-lang:scala-compiler:2.10.5'

  compile 'org.scalanlp:breeze_2.10:0.11.2'

  compile group: 'org.apache.flink', name: 'flink-clients', version: '0.9-SNAPSHOT'
  compile group: 'org.apache.flink', name: 'flink-scala', version: '0.9-SNAPSHOT'
  compile group: 'org.apache.flink', name: 'flink-ml', version: '0.9-SNAPSHOT'
}

And I get the following error:

alber@alberTU:/media/alber/datadisk/tmp/flink/code/test$ gradle compileScala

I'm thankful for any ideas!
