Sent this to d...@flink.apache.org <mailto:d...@flink.apache.org>, but that might not be the appropriate forum for it.
Finally got a chance to sit down and run through a few tests. Upfront, I have been able to resolve my issue sufficiently to move forward, but seems there’s an issue with the current bits for both 1.0-SNAPSHOT and 0.10-SNAPSHOT in the remote Maven repos. Notes wordcount-processing <https://github.com/OCExercise/wordcount-processing> is a customized version of the Flink quickstart archetype I’m using to test Flink integration with Spring Boot. It is instrumented for Maven and Gradle build and execution. I’m targeting Scala 2.11 and Flink 0.10. 0.10-SNAPSHOT source build Steps Checked out release–0.10 branch (snapshot version 0.10-SNAPSHOT). Built with mvn clean install -DskipTests=true -Dmaven.javadoc.skip=true -Dscala.version=2.11.7 -Dscala.binary.version=2.11. Ran wordcount-process with mvn clean spring-boot:run -Drun.arguments=“localhost,9999”. Ran wordcount-process with gradle bootRun -Drun.arguments=“localhost 9999”. Result Maven execution of test succeeds without incident. Gradle execution of test succeeds without incident. 0.10-SNAPSHOT with fetched binary dependencies Steps Cleaned out local maven repository with rm -rf $HOME/.m2/repo/org/apache/flink && rm -rf $HOME/.m2/repo/org/scala*. Cleaned out local gradle repository with rm -rf $HOME/.gradle/caches/modules-2/files-2.1/org.apache.flink && rm -rf $HOME/.gradle/caches/modules-2/files-2.1/org.scala*. Ran wordcount-process with mvn clean spring-boot:run -Drun.arguments=“localhost,9999”. Ran wordcount-process with gradle bootRun -Drun.arguments=“localhost 9999”. Result Maven build completed without incident. Maven execution error’d out with issue supposedly resolved with pull request 1511 <https://github.com/apache/flink/pull/1511>. Gradle execution of test succeeds without incident. 1.0-SNAPSHOT source build Steps Cleaned out local maven repository with rm -rf $HOME/.m2/repo/org/apache/flink && rm -rf $HOME/.m2/repo/org/scala*. Cleaned out local gradle repository with rm -rf $HOME/.gradle/caches/modules-2/files-2.1/org.apache.flink && rm -rf $HOME/.gradle/caches/modules-2/files-2.1/org.scala*.

Result Maven build error’d out with could not find implicit value for evidence parameter of type org.apache.flink.api.common.typeinfo.TypeInformation[String], and can't expand macros compiled by previous versions of Scala[ERROR] val text = env.fromElements("To be, or not to be,--that is the question:—“. (Gist <https://gist.github.com/revprez/c70a6f3976b091413c8c>). Gradle build error’d out with java.lang.NoClassDefFoundError: scala/reflect/macros/Context (gist <https://gist.github.com/revprez/298a0302711908975add>). Discussion As it stands, I can move forward with building 0.10-SNAPSHOT from source for my own purposes. I’m guessing pull request 1511 <https://github.com/apache/flink/pull/1511> hasn’t made it into the the upstream snapshot repos yet. I’m not sure as to why 1.0-SNAPSHOT is suffering from a macros incident and not 0.10-SNAPSHOT. Both are bringing in dependencies (quasiquotes, scala-library, scala-reflect, and a bunch of akka-* stuff) compiled for 2.10, but 0.10-SNAPSHOT does not invite the macro-related errors some of us have seen when building against 1.0-SNAPSHOT dependencies.
