DFLib / Parquet and Avro classpath issues #30
Description
Another classpath issue potentially related to Ivy. We can't work with Parquet or Avro APIs. It works well in a standalone Java app, as well as in JShell (with /env --class-path taken from the Java app). But in Jupyter (jjava M2) the code fails with NoClassDefFoundError.
I vaguely remember this happening with Avro back in the iJava days as well, though we ignored it cause we could not do anything about it.
Parquet
%maven org.dflib:dflib-jupyter:1.0.0-SNAPSHOT
// the error is the same with or without this dependency
// %maven com.fasterxml.woodstox:woodstox-core:5.4.0
