ClassNotFoundException: org.apache.flink.api.common.io.OutputFormat

After generating the shadow jar via

> gradle shadowJar

I get a java.lang.NoClassDefFoundError when running the builder:

> java -jar build/libs/sharedstreets-builder-0.3.1-all.jar
Error: A JNI error has occurred, please check your installation and try again

Apparently, the implicit flink-core dependency is not included in the shadow.jar.

build.gradle defines a task 'allJars' which generates a shadow jar containing all required libs.

So I had to build using

> gradle allJars
