swagger-codegen-maven-plugin

A Maven plugin to support the swagger code generation project

Usage

Add to your build->plugins section (default phase is generate-sources phase)

<plugin>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-codegen-maven-plugin</artifactId>
    <version>2.1.5-SNAPSHOT</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <inputSpec>src/main/resources/api.yaml</inputSpec>
                <language>java</language>
                <configOptions>
                   <sourceFolder>src/gen/java/main</sourceFolder>
                </configOptions>
            </configuration>
        </execution>
    </executions>
</plugin>

Followed by:

mvn clean compile

General Configuration parameters

• inputSpec - OpenAPI Spec file path
• language - target generation language
• output - target output path (default is ${project.build.directory}/generated-sources/swagger)
• templateDirectory - directory with mustache templates
• addCompileSourceRoot - add the output directory to the project as a source root (true by default)
• modelPackage - the package to use for generated model objects/classes
• apiPackage - the package to use for generated api objects/classes
• invokerPackage - the package to use for the generated invoker objects
• configOptions - a map of language-specific parameters (see below)
• configHelp - dumps the configuration help for the specified library (generates no sources)

Custom Generator

Specifying a custom generator is a bit different. It doesn't support the classpath:/ syntax, but it does support the fully qualified name of the package. You can also specify your custom templates, which also get pulled in. Notice the dependency on a project, in the plugin scope. That would be your generator/template jar.
