Joe Barnett commented on MDEP-840:
----------------------------------

javap -c output of kotlin version:
{code:java}
Compiled from "Example.kt"
public final class mdep840.Example {
  public mdep840.Example();
    Code:
       0: aload_0
       1: invokespecial #8                  // Method 
java/lang/Object."<init>":()V
       4: return  public final void invokeBinder();
    Code:
       0: new           #13                 // class 
io/dropwizard/auth/AuthValueFactoryProvider$Binder
       3: dup
       4: ldc           #15                 // class java/security/Principal
       6: invokespecial #18                 // Method 
io/dropwizard/auth/AuthValueFactoryProvider$Binder."<init>":(Ljava/lang/Class;)V
       9: pop
      10: return
}
{code}
and java version:
{code:java}
Compiled from "Example.java"
class mdep840.Example {
  mdep840.Example();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method 
java/lang/Object."<init>":()V
       4: return  public void invokeBinder();
    Code:
       0: new           #7                  // class 
io/dropwizard/auth/AuthValueFactoryProvider$Binder
       3: dup
       4: ldc           #9                  // class java/security/Principal
       6: invokespecial #11                 // Method 
io/dropwizard/auth/AuthValueFactoryProvider$Binder."<init>":(Ljava/lang/Class;)V
       9: pop
      10: return
}
{code}
but not sure that shows anything appreciably different?

>                 Key: MDEP-840
>                 URL: https://issues.apache.org/jira/browse/MDEP-840
>             Project: Maven Dependency Plugin
>          Issue Type: Bug
>          Components: analyze-only
>    Affects Versions: 3.4.0
>            Reporter: Joe Barnett
>            Priority: Major
>
> We have a class here: 
> [https://github.com/trib3/leakycauldron/blob/main/testing/src/main/kotlin/com/trib3/testing/server/ResourceTestBase.kt]
>  
> that imports io.dropwizard.auth.AuthValueFactoryProvider from 
> io.dropwizard:dropwizard-auth, and the pom declares that dependency directly.
>  
> Starting with maven-dependency-plugin 3.4.0, we now get this error when 
> running the analyze-only goal:
> {code:java}
> [ERROR] Unused declared dependencies found:
> [ERROR]    io.dropwizard:dropwizard-auth:jar:2.1.4:compile{code}
>  
> removing the declared dependency results in the code failing to compile since 
> dropwizard-auth is no longer on the classpath.  This worked in 3.3.0.
