OpenAPI Generator gradle plugin task not executed - gradle

Question

In my android project I am trying to include the openapi-generator plugin to generate a client. I've copied the instructions from the readme for my project. Unfortunately, the task doesen't seem to be executed.
I am new to gradle and android. So I haven't a lot of knowledge on these subjects yet.
This is the projects build.gradle file:
buildscript {
ext {
nav_version = '2.4.2'
}
dependencies {
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
classpath "org.openapitools:openapi-generator-gradle-plugin:5.4.0"
}
}
plugins {
id 'com.android.application' version '7.1.3' apply false
id 'com.android.library' version '7.1.3' apply false
id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
}
task clean(type: Delete) {
delete rootProject.buildDir
}
This is the build.gradle file of my module:
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'androidx.navigation.safeargs.kotlin'
id 'kotlin-kapt'
id "org.openapi.generator"
}
android {
compileSdk 31
defaultConfig {
applicationId "..."
minSdk 29
targetSdk 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {

targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures {

}
sourceSets {

kotlin {

}
}
}
}

}
openApiGenerate {
generatorName = "kotlin"
inputSpec = "$rootDir/app/src/main/assets/swagger.yml".toString()
outputDir = "$buildDir/generated".toString()
apiPackage = "org.openapi.example.api"
invokerPackage = "org.openapi.example.invoker"
modelPackage = "org.openapi.example.model"
configOptions = [
dateLibrary: "java8"
]
}
In the output of the build was no hint that the openApiGenerate task was executed and on the filesystem I didn't find the generated client.
Probably there is a mistake in the configuration, but I don't know what is wrong.
Can you help me?

Answer 1

This command should generate the client :
./gradlew openApiGenerate
If you want to avoid manually running this every time your schema changes, then you can go to the drop down here:
Now choose edit configurations:
Now add a gradle task with the + button:
Then:
Enter the task in run:
Now edit the app configuration, by adding what you just created to the before launch section:
You will see the YourAppsName[openApiGenerate] configuration you created as an option, so select that, then apply changes, and now every time you run your application your client will be built.
