Description

When executing a code generation for the provided specification with 7.7.0 the generated file will contain validation annotation from the package "javax.validation". When doing the same in version 7.8.0 the corresponding annotations are imported from the package "jakarta.validation", even though there is a config option "useJakartaEe" that is set to false and claims to control this behavior.

openapi-generator version

7.8.0 contains the issue

7.7.0 is working fine

Generation Details

Gradle plugin definition:

task generateTest(type: GenerateTask)
tasks.named("generateCustomerEvent").get().setProperty("inputSpec", "PutLocationOfFileHere")

tasks.withType(GenerateTask).configureEach {
  generatorName = "java"
  outputDir = "${buildDir}/generated/sources"

  configOptions = [
    performBeanValidation: "true",
    useBeanValidation: "true",
    library: "webclient",
    dateLibrary: "custom",
    useJakartaEe: "false"
  ]
  globalProperties = [
    apis: "false",
    models: ""

  typeMappings = [
    DateTime: "Instant",
    Date: "java.time.LocalDate",
    Uuid: "UUID"
  ]
  importMappings = [
    Instant: "java.time.Instant",
    UUID: "java.util.UUID"
  ]
}

Steps to reproduce

Execute the generation for the provided specification in version 7.7.0 and 7.8.0.

#18332 and #19171 aligned the validation-api to use jakarta.* package as a previous commit had already upgraded the validation-api version to 3.x. Unfortunately this caused a regression as end users can manually specify 2.x, in which case they would still need the javax.* package.

I'll raise a PR to fix this in the coming days
