Which queryDSL to use?

[Al Grant]

Hello,

I am a complete newbie and just starting out to use queryDSL but can't even get as far as getting my Q classes generated.

I am using Spring-Boot 1.5.2

Hibernate

Intellij

Gradle

I am not even sure if I should be using:

com.querydsl or com.mysema.querydsl?

My build.gradle is outlined below:

buildscript {
   ext {
      springBootVersion = '1.5.2.RELEASE'
      querydslVersion = '4.1.4'
   }
   repositories {
      mavenCentral()
   }
   dependencies {
      classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
   }
}
plugins {
   id 'net.ltgt.apt' version '0.8'
   id 'java'
}

ext["thymeleaf.version"] = "3.0.0.RELEASE"
ext["thymeleaf-layout-dialect.version"] = "2.0.1"

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'idea'

sourceSets {
   generated
}
sourceSets.generated.java.srcDirs = ['src/main/generated']
configurations {
   querydslapt
}

version = '0.0.5-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
   mavenCentral()

Hello,

If you're just starting out, I'd recommend com.querydsl
That's Querydsl 4, and com.mysema.querydsl is Querydsl 3

However if one of the dependencies relies on just one version you can't pick so you'll have to find that out.

Best regards,
Ruben
