When I use Spring Framework 6.x, I can mix up packaging normally, but the controller reports an error after running it

use:

<plugin>
    <groupId>com.github.wvengen</groupId>
    <artifactId>proguard-maven-plugin</artifactId>
    <version>2.6.1</version>
    ...
<plugin>

error:

Name for argument of type [java.lang.String] not specified, and parameter name information not available via reflection. Ensure that the compiler uses the '-parameters' flag.

Spring prompts for use:

I had a similar problem after upgrading SpringBoot (to 3.3). For me I needed to add -keepattributes MethodParameters to my proguard config in combination with the compiler '-parameters' flag seems to get it working
