Querydsl 적용하기 (java, kotlin)

Querydsl 적용하기

build.gradle

buildscript {
    ext {
        queryDslVersion = "5.0.0"
    }
}


plugins {
    id 'com.ewerk.gradle.plugins.querydsl' version '1.0.10'
}

dependencies {
    implementation "com.querydsl:querydsl-jpa:${queryDslVersion}"
    implementation "com.querydsl:querydsl-apt:${queryDslVersion}"
}

def querydslDir = "$buildDir/generated/querydsl"

querydsl {
    jpa = true
    querydslSourcesDir = querydslDir
}

sourceSets {
    main.java.srcDir querydslDir
}

configurations {
    querydsl.extendsFrom compileClasspath
}

compileQuerydsl {
    options.annotationProcessorPath = configurations.querydsl
}

Querydsl 버전을 명시 안해줬을때 Unable to load class 'com.mysema.codegen.model.Type'. 라는 에러가 발생했다.
