Re: Compiling Flink for Scala 2.11

[Fabian Hueske]

Hi Markus,

thanks for reporting this issue. This bug was introduced when the opt.xml
file was added to the repository a few days ago.
There are two open JIRAs, FLINK-5392 and FLINK-5396, each one with a pull
request to fix the problem.

Best, Fabian

Compiling Flink for Scala 2.11

[M. Dale]

I cloned the Apache Flink source code from 
https://github.com/apache/flink and

want to build the 1.2-SNAPSHOT with Scala 2.11.

git clone g...@github.com:apache/flink.git
cd flink
git checkout remotes/origin/release-1.2

Following instructions from the 1.2 docs at
https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/building.html
I then:

tools/change-scala-version.sh 2.11
mvn clean install -DskipTests (I am using Maven 3.3.9)

This gets to flink-dist and then:
[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-assembly-plugin:2.4:single (opt)
on project flink-dist_2.11: Failed to create assembly: Error adding file 
to archive:
//flink/flink-dist/../flink-libraries/flink-cep/target/flink-cep_2.10-1.2-SNAPSHOT.jar 
isn't a file.


It seems that flink/flink-dist/src/main/assemblies/opt.xml does not get 
changed

by the change-scala-version.sh script and still has some 2.10 dependencies.

Did I miss a step? There are 2.11 artifacts in the Maven repos. I see 
the parent pom has a scala.version variable but mostly

the scala version is just hardcoded in the poms and controlled via the tools
script. Changing the _2.10 references in opt.xml allows for successful 
compile.
Please advise whether I should file a Jira and pull request to add 
opt.xml to
the change-scala-version.sh script? Or is there a new/different way to 
build for 2.11?


Thanks,
Markus
