将JOOQ与Kotlin Gradle DSL一起使用

Question

我正在尝试使用Kotlin DSL在Gradle中设置JOOQ代码生成，但是当我运行Generator Task时，我正在获得错误“无法实例化的注释类”。我想念什么？

这是build.gradle.kts

import org.jooq.meta.jaxb.*
import org.jooq.codegen.GenerationTool

plugins {
    id("java")
    id("java-library")
}

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.jooq:jooq-codegen:3.16.6")
        classpath("org.postgresql:postgresql:42.3.5")
    }
}

repositories {
    google()
    mavenCentral()
}

dependencies {
    compileOnly("org.jooq:jooq:3.16.6")
    compileOnly("org.jooq:jooq-codegen:3.16.6")
    runtimeOnly("org.postgresql:postgresql:42.3.5")
}

group = "com.example"
version = "1.0-SNAPSHOT"

// Set the following system properties to enable JOOQ to connect to the DB
// -Djooq.codegen.jdbc.user
// -Djooq.codegen.jdbc.password
//
tasks.create("generate") {
    GenerationTool.generate(Configuration()
            .withJdbc(Jdbc()
                    .withDriver("org.postgresql.Driver")
                    .withUrl("jdbc:postgresql://localhost:5432/postgres"))
            .withGenerator(Generator()
                    .withDatabase(Database().withInputSchema("public"))
                    .withGenerate(Generate())
                    .withTarget(Target()
                            .withPackageName("com.example.db")
                            .withDirectory("src/generated/jooq"))))
}

，这是stacktrace：

ScriptCompilationException(errors=[ScriptCompilationError(message=Annotation class cannot be instantiated, location=/Users/foo/.gradle/.tmp/gradle-kotlin-dsl-12544449971161496170.tmp/build.gradle.kts (51:33)), ScriptCompilationError(message=Unresolved reference: withPackageName, location=/Users/foo/.gradle/.tmp/gradle-kotlin-dsl-12544449971161496170.tmp/build.gradle.kts (52:30))])

问题是由于班级目标被注释所掩盖。修复程序是添加一个明确的导入：导入org.jooq.meta.jaxb.target

所有这些都归功于@Jorn和@lukas Eder进行修复。
