Description

In a very similar manner to the same issue with java-native generator, the annotationLibrary option is being ignored in the spring generator, resulting in obsolete and conflicting imports being added to the model classes.

openapi-generator version

The issue is present in 7.16.0.

Generation Details

In build.gradle:

import org.openapitools.generator.gradle.plugin.tasks.GenerateTask

plugins {
    id 'org.openapi.generator' version '7.15.0
}

ext {
    openAPIGeneratorVersion = '7.15.0'
    jakartaAnnotationVersion = '2.1.1'
    jacksonDatabindNullableVersion = '0.2.6'
}

dependencies {
    implementation ("org.openapitools:openapi-generator:$openAPIGeneratorVersion") {
        exclude group: 'org.slf4j', module: 'slf4j-simple'
    }

    implementation "org.openapitools:jackson-databind-nullable:$jacksonDatabindNullableVersion"
    implementation "jakarta.annotation:jakarta.annotation-api:$jakartaAnnotationVersion"
}

tasks.register('generateOpenAPI', GenerateTask) {
    generatorName = "spring"
    inputSpec = "$rootDir/api/api-v1.yml"
    outputDir = "$projectDir"
    ignoreFileOverride = "$projectDir/.openapi-generator-ignore"
    apiPackage = "com.myapp.api"
    modelPackage = "com.myapp.model"
    configOptions = [
            booleanGetterPrefix  : "is",
            interfaceOnly        : "true",
            openApiNullable      : "false",
            skipDefaultInterface : "true",
            documentationProvider: "none",

            useEnumCaseInsensitive: "true",
            useJakartaEe: "true"
    ]
    globalProperties = [
            apis: "",
            models: "",
    ]
    additionalProperties = [
            removeEnumValuePrefix: "false",
    ]
}

tasks.named('compileJava') {
    dependsOn tasks.named('generateOpenAPI')
}

tasks.withType(ProcessResources).configureEach {
    dependsOn 'generateOpenAPI'
}

compileJava {
    options.release = 17

    sourceCompatibility = "17"
    targetCompatibility = "17"
}

Trying to build a project with the above configuration results in a compile-time error:
