## Maven
A Maven plugin to support the OpenAPI generator project
### Example
Add to your `build->plugins` section (default phase is `generate-sources` phase)
```xml
<plugin>
<groupId>org.openapitools</groupId>
<artifactId>openapi-generator-maven-plugin</artifactId>
<version>3.3.4</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<inputSpec>${project.basedir}/src/main/resources/api.yaml</inputSpec>
<generatorName>java</generatorName>
<configOptions>
<sourceFolder>src/gen/java/main</sourceFolder>
</configOptions>
</configuration>
</execution>
</executions>
</plugin>
```
Followed by:
```bash
mvn clean compile
```
For full details of all options, see the [plugin README](https://github.com/OpenAPITools/openapi-generator/tree/master/modules/openapi-generator-maven-plugin).
## Gradle
This gradle plugin offers a declarative DSL via extensions (these are Gradle project extensions). These map almost fully 1:1 with the options youd pass to the CLI or Maven plugin. The plugin maps the extensions to a task of the same name to provide a clean API. If youre interested in the extension/task mapping concept from a high-level, you can check out [Gradles docs](https://docs.gradle.org/current/userguide/custom_plugins.html#sec:mapping_extension_properties_to_task_properties).
To include in your project, add the following to `build.gradle`:
```groovy
buildscript {
repositories {
mavenLocal()
maven { url "https://repo1.maven.org/maven2" }
}
dependencies {
classpath "org.openapitools:openapi-generator-gradle-plugin:3.3.4"
}
}
apply plugin: 'org.openapi.generator'
```
This gives access to the following tasks:
| Task | Description |
| ---- | ----------- |
| openApiGenerate | Generate code via Open API Tools Generator for Open API 2.0 or 3.x specification documents. |
| openApiGenerators | Lists generators available via Open API Generators. |
| openApiMeta | Generates a new generator to be consumed via Open API Generator. |
| openApiValidate | Validates an Open API 2.0 or 3.x specification document. |
> The plugin implements the above tasks as project extensions of the same name. If youd like to declare these tasks as dependencies to other tasks (using `dependsOn`), youll need a task reference. e.g.:
> ```groovy
> compileJava.dependsOn tasks.openApiGenerate
> ```
For full details of all options, see the [plugin README](https://github.com/OpenAPITools/openapi-generator/tree/master/modules/openapi-generator-gradle-plugin).
### Example
An example task for generating a kotlin client:
```groovy
openApiGenerate {
generatorName = "kotlin"
inputSpec = "$rootDir/specs/petstore-v3.0.yaml".toString()
outputDir = "$buildDir/generated".toString()
apiPackage = "org.openapi.example.api"
invokerPackage = "org.openapi.example.invoker"
modelPackage = "org.openapi.example.model"
modelFilesConstrainedTo = [
"Error"
]
configOptions = [
dateLibrary: "java8"
]
}
```
