mapstruct and gradle configuratoin issue in Intellij IDEA

Question

I have a project using gradle, and have mapstruct as one of dependency. everytime I tried to build project, it failed. I guess it is because Mapstruct will generate impl class that gradle was not able to find. Can anyone help me how to configure this in intellij IDEA?

Thanks

Answer 1

This works for me

In intellij IDEA go to

File | Settings | Build, Execution, Deployment | Build Tools | Gradle | Runner

Enable Delegate IDE build/run actions. Ref :- https://www.jetbrains.com/idea/whatsnew/#v2016-3-gradle

In build.gradle

buildscript {
    ...    
}
plugins {
    id 'net.ltgt.apt' version '0.9'
}

apply plugin: 'idea'
apply plugin: "net.ltgt.apt"

dependencies {
    ...
    compile 'org.mapstruct:mapstruct-jdk8:1.1.0.Final'
    apt 'org.mapstruct:mapstruct-processor:1.1.0.Final'
}

After Adding this configuration Run your project you can see your generated files in build/generated folder

Answer 2

Hey there everyone I had the same issue and found a clean way of solving this issue. I am using two libraries that require annotation processing (Lombok and MapStruct).

Also my IntelliJ is 2019.1 (update yours in case it's older) and Gradle 5.2.1.

First let's configure IntelliJ:

1. Disable Annotaion Processing in Settings, since we're going to delegate everything to Gradle:

2. Delegeate IDE actions to Gradle:

Last step is to configure your dependencies correctly in Gradle.

3. Dependencies section in Gradle:

Now you can execute the Build and Run from both command line and IDE.

Cheers!
