EXCEL_DATA_SOURCE_NOT_ENABLED Excel data source is not enabled in this cluster

[der]

I want to read an Excel xlsx file on DBR 17.3. On the Cluster the library dev.mauch:spark-excel_2.13:4.0.0_0.31.2 is installed. 

V1 Implementation works fine:

df = spark.read.format("dev.mauch.spark.excel").schema(schema).load(excel_file)
display(df)

V2 throws [EXCEL_DATA_SOURCE_NOT_ENABLED] Excel data source is not enabled in this cluster. SQLSTATE: 56038

df = spark.read.format("excel").schema(schema).load(excel_file)
display(df)

I wonder, why do we have specific excel error codes and how do we enable the excel data source?

If I build the spark-excel library with another short name (example "excelv2"), everything works fine.
