java - Gradle 的 QueryDSL 问题

Question

我正在将 QueryDSL 与 Lombok 和 gradle 结合使用。 Q 类正在生成，IDEA 也可以看到它们并且没有编译器错误但是当我尝试执行 gradle build 时我得到:

error: cannot find symbol
import QRole;

因此生成了文件，但 gradle build like 看不到它们。我发现的所有解决方案都不起作用，无论我做什么，我仍然会收到此错误。这是我的 gradle.build :

Answer 1

同时使用 Gradle、QueryDSL 和 Lombok 是一项棘手的工作，但幸运的是，几乎没有插件可以让这一切变得简单。这是有效的代码。

plugins {
    id 'org.springframework.boot' version '2.6.4'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
    id 'idea'
    id 'io.franzbecker.gradle-lombok' version '5.0.0'
    id 'com.ewerk.gradle.plugins.querydsl' version '1.0.10'
}

querydsl {
    library = 'com.querydsl:querydsl-apt:5.0.0'
    jpa = true
}

configurations {
    querydsl.extendsFrom implementation, compileClasspath
}

compileQuerydsl {
    options.annotationProcessorPath = configurations.querydsl
}

project.afterEvaluate {
    project.tasks.compileQuerydsl.options.compilerArgs = [
            "-proc:only",
            "-processor", project.querydsl.processors() +
                    ',lombok.launch.AnnotationProcessorHider$AnnotationProcessor'
    ]
}

sourceSets {
    main {
        java {
            srcDirs = ['src/main/java', 'src/querydsl/java']
        }
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'com.querydsl:querydsl-jpa:5.0.0'
}

io.franzbecker.gradle-lombok 和 com.ewerk.gradle.plugins.querydsl 是所有 3 个正确工作所需的插件。
