[Oracle] [SchemaSpy] Catalog (-cat) was not provided and unable to deduce catalog, wildcard catalog can be used -cat %

Problem
When I try to generate schema document via SchemaSpy, I got the following error message:

Catalog (-cat) was not provided and unable to deduce catalog, wildcard catalog can be used -cat %

I used schemaspy-6.1.0 and graphviz-2.38.


How-To
The root cause is uncertain, but this problem can be resolved by adding -cat "%"  in your command line.
