Hello guys, Just wondering if someone can help me out with this very first pull request - the travis-ci failed during Tests phase : https://travis-ci.org/apache/flink/builds/494787984
The error seems unrelevant to my change though, do I need some trick to fix it here? 10:42:12.053 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project flink-scala_2.11: Compilation failure: Compilation failure: 10:42:12.053 [ERROR] /home/travis/build/apache/flink/flink-scala/src/main/java/org/apache/flink/api/scala/typeutils/TraversableSerializerSnapshot.java:[55,50] cannot find symbol 10:42:12.053 [ERROR] symbol: method cbfCode() 10:42:12.053 [ERROR] location: variable serializerInstance of type org.apache.flink.api.scala.typeutils.TraversableSerializer<T,E> 10:42:12.053 [ERROR] /home/travis/build/apache/flink/flink-scala/src/main/java/org/apache/flink/api/scala/typeutils/TraversableSerializerSnapshot.java:[84,24] org.apache.flink.api.scala.typeutils.TraversableSerializer is abstract; cannot be instantiated 10:42:12.053 [ERROR] /home/travis/build/apache/flink/flink-scala/src/main/java/org/apache/flink/api/scala/typeutils/TraversableSerializerSnapshot.java:[102,52] cannot find symbol 10:42:12.053 [ERROR] symbol: method cbfCode() 10:42:12.053 [ERROR] location: variable newSerializer of type org.apache.flink.api.scala.typeutils.TraversableSerializer<T,E> Cheers, Feng
