[BUG] Jackson dependency required when okhttp-gson is choosen

[efren1villamagua]

The generated code for java with okhttp-json has a problem.

For some in-house reason we can't use Jackson libraries. Until version 7.2.0 the file JSON.java is generated with a Google dependency (com.google.gson.internal.bind.util.ISO8601Utils) but from 7.3.0 version a Jackson dependency is used (com.fasterxml.jackson.databind.util.StdDateFormat) what causes a compilation error.

Dependency used in my project is: org.openapitools:openapi-generator-gradle-plugin:7.5.0

Configuration is:

openApiGenerate {
    generatorName = "java"
    library = "okhttp-gson"
    inputSpec = "...".toString()
    outputDir = "...".toString()
    apiPackage = "..."
    invokerPackage = "..."
    modelPackage = "..."
    configOptions = [
            dateLibrary                             : "java8",
            disallowAdditionalPropertiesIfNotPresent: "false",
            enumUnknownDefaultCase                  : "true",
            useOneOfDiscriminatorLookup             : "true"
    ]
    globalProperties = [
            skipFormModel: "false",
            apiTests     : "false",
            modelTests   : "false"
    ]
    skipValidateSpec = true
    logToStderr = true
    generateAliasAsModel = false
    enablePostProcessFile = false
    cleanupOutput = true
}
