--source.location=swagger.yaml \
--target.model.location=./generated \
--target.model.model-package=com.example.model \
--target.client.location=./generated \
--target.client.model-package=com.example.model \
--target.client.client-package=com.example.client \

Run from gradle

There is no specific gradle plugin yet, but you can run code generator from gradle using command line version:

configurations {
   swagger
}
 
dependencies {
   swagger 'com.github.agliznetsov.swagger-tools:swagger-tools-cli:0.8.3'
}
 
task "swagger-generate"(type: JavaExec) {
   classpath = configurations.swagger
   main = 'org.swaggertools.cli.Generator'
   args = [
         "--source.location", "src/main/resources/swagger.yaml",
         "--target.model.location", "src/main/java",
         "--target.model.model-package", "com.example.model",
   ]
}
