我有一个Maven，Kotlin，QueryDSL，Spring Boot和MongoDB的项目。它运行良好，但我认为迁移到Gradle可以加快构建速度。在我开始使用QueryDSL迁移模块之前，一切都很好。事实证明，我无法为使用@Document注释的Kotlin类生成Q类。 有办法解决吗？ 文档示例（将/ src / main / kotlin / com / company放在kotlin目录中）：

package ...
import org.springframework.data.annotation.Id
import org.springframework.data.mongodb.core.mapping.Document

@Document(collection = "myDocument")
data class MyDocument(
        val smth: String
)

对于gradle + kotlin AFAIU，我们必须使用kapt以这种方式生成Q类

kapt("com.querydsl:querydsl-apt:4.2.1:jpa")

但这对我不起作用，我的新build.gradle.kts：

import org.jetbrains.kotlin.gradle.plugin.KotlinSourceSet
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "2.2.0.RELEASE"
    id("io.spring.dependency-management") version "1.0.8.RELEASE"
    kotlin("jvm") version "1.3.50"
    kotlin("kapt") version "1.3.50"
    kotlin("plugin.jpa") version "1.3.50"
    id("org.jetbrains.kotlin.plugin.spring") version "1.3.21"
}

apply(plugin = "kotlin")
apply(plugin = "kotlin-kapt")
apply(plugin = "kotlin-jpa")
apply(plugin = "org.springframework.boot")
apply(plugin = "io.spring.dependency-management")


group = "com.example"
version = "0.0.1-snAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_1_8

repositories {
    mavenCentral()
}


dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("com.querydsl:querydsl-jpa")
    implementation("com.querydsl:querydsl-apt")

    kapt("com.querydsl:querydsl-apt:4.2.1:jpa")
    kapt("org.springframework.boot:spring-boot-starter-data-jpa")
    kapt("org.springframework.boot:spring-boot-configuration-processor")
    kapt("org.springframework.data:spring-data-mongodb:2.2.0.RELEASE")


    implementation("org.springframework.boot:spring-boot-starter-data-mongodb")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    testImplementation("org.springframework.boot:spring-boot-starter-test") {
        exclude(group = "org.junit.vintage",module = "junit-vintage-engine")
    }
}

//sourceSets { main["kotlin"].srcDirs += [generated] }
//val querydslSrcDir = "src/main/generated"

tasks.withType<Test> {
    useJUnitPlatform()
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

在Maven中，我可以精确设置注释处理器（org.springframework.data.mongodb.repository.support.MongoannotationProcessor），但在gradle中，我不知道如何实现它。
