Null key returned for cache operation and Parameter name information not available via reflection. Ensure that the compiler uses the '-parameters' flag.

[manjinderrooprai]

On updating our application to Spring Boot 3.2.5 and Spring framework 6.1.6. we are getting following Errors.

ERROR c.a.s.t.c.e.ControllerExceptionHandler - java.lang.IllegalArgumentException: 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.
java.lang.IllegalArgumentException: 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.

ERROR c.a.s.t.c.e.ControllerExceptionHandler - java.lang.IllegalArgumentException: Null key returned for cache operation  caches=['cacheExample'] | key='#cacheKey' | keyGenerator='' | cacheManager='' | cacheResolver='' | condition='' | unless='' | sync='true']. If you are using named parameters, ensure that the compiler uses the '-parameters' flag.

It seams, it is asking to compile(java) code with '-parameters' flag. So for that, I have followed the directions on https://github.com/spring-projects/spring-framework/wiki/Upgrading-to-Spring-Framework-6.x#parameter-name-retention:

I have added:

tasks.withType(JavaCompile).configureEach {
    options.compilerArgs.add("-parameters")
}

Even i had tried adding following mentioned in Thread: https://github.com/spring-projects/spring-framework/issues/31729

 tasks.withType(JavaCompile) {
        configure(options) {
            options.compilerArgs << '-parameters'
        }
    }

Nothing works for me.

I am using Vscode 1.88.1 with following configuration: springBootVersion= 3.2.5 springFrameworkVersion= 6.1.6 Java= 17.0.5 gradle= 8.7

Could you please help me in resolving this issue.
