Description

Description:

Due to collision of shaded packages 

shaded.parquet.it.unimi.dsi.fastutil

in 

org.apache.parquet:parquet-avro

and 

org.apache.parquet:parquet-column

it is not possible to use both these dependencies within a modularized java project at the same time.

 

 

How to reproduce:

• create a maven project with dependency org.apache.parquet:parquet-avro:1.11.1
• declare java module that requires both parquet.avro and parquet.column
• run

  mvn compile

 

Expected behaviour:

Project should compile without errors.

 

Actual behaviour:

Project fails with compilation errors:

 

[ERROR] the unnamed module reads package shaded.parquet.it.unimi.dsi.fastutil from both parquet.column and parquet.avro
...
