Description

I try to add per-class NoException annotation instead of per-function

infoMap.put(new Info("namespace::Someclass").annotations("@NoException"));

got the following errors

annotation type not applicable to this kind of declaration

the generated code looks like this

public native int do(@NoException @SharedPtr Someclass variable);

See mailing list thread for details: https://groups.google.com/g/javacpp-project/c/zzGRu019BoA

Contributor guide

Research direction
Investigate the code generation logic that handles @NoException annotation. Trace how the annotation is applied to method arguments and ensure it is only applied to methods as intended, not to parameters. Look for where the annotation is copied from the class to the parameter.
