Generation Details

    default ResponseEntity<FetchCustomerResponse> fetchCustomer(
         @Valid @RequestParam(value = "fields.customers", required = false) String fieldsCustomers,
         @Valid @RequestParam(value = "include", required = false) String include,
         @Valid @RequestParam(value = "fields.profiles", required = false) String fieldsProfiles,

Steps to reproduce

openApiGenerate {
    generatorName = "java"
    library = "microprofile"
    inputSpec = "$projectDir/src/main/resources/openapi.json".toString()
    outputDir = layout.buildDirectory.dir("generated/sources/openapi").get().toString()
    configOptions.putAll([
        openApiNullable          : "false",
        serializationLibrary     : "jackson",
        annotationLibrary        : "none",
        documentationProvider    : "none",
        useSingleRequestParameter: "true",
        implicitHeaders          : "true",
    ])
    typeMappings.putAll([
        // Override unsupported anyOf on metadata.value
        "MetadataDetailValue": "Object"
    ])

Start with the Gradle openApiGenerate configuration in the issue, using the Java generator with the microprofile library and useSingleRequestParameter enabled. Reproduce the generation from the provided OpenAPI declaration and inspect the generated fetchCustomer interface; done means the reported single-request-parameter behavior is understood and corrected or the issue is clarified with a focused reproduction.
