This plugin was based on kongchen's swagger-maven-plugin
This enables your Swagger-annotated project to generate Swagger specs and customizable, templated static documents during the gradle build phase. Unlike swagger-core, swagger-gradle-plugin does not actively serve the spec with the rest of the application; it generates the spec as a build artifact to be used in downstream Swagger tooling.
N.B This plugin is tested against the latest of each major Gradle version from 3.x onwards. The reason for 3.x, is that 3.2 was the first that supported Kotlin, therefore keeping tests simpler. This does not mean that this plugin won't work with earlier versions, just your mileage may vary.
- Supports Swagger Spec 2.0
- Supports SpringMvc & JAX-RS
- Use Handlebars as template to customize the static document.
Import the plugin in your project by adding following configuration:
plugins {
id 'com.benjaminsproule.swagger' version '1.0.8'
}plugins {
id("com.benjaminsproule.swagger") version "1.0.8"
}buildscript {
repositories {
maven {
url 'https://plugins.gradle.org/m2/'
}
}
dependencies {
classpath 'gradle.plugin.com.benjaminsproule:swagger-gradle-plugin:1.0.0'
}
}
apply plugin: 'com.benjaminsproule.swagger'
swagger {
apiSource {
...
}
}One apiSource can be considered as a version of APIs of your service.
You can specify several apiSources. Generally, one is enough.
swagger {

}| name | description |
|---|---|
apiSources |
List of apiSource closures. One apiSource can be considered as a version of APIs of your service. You can specify several apiSource closures, though generally one is enough. |
| name | description |
|---|---|
springmvc |
Tell the plugin your project is a JAX-RS(false) or a SpringMvc(true) project |
locations required |
Classes containing Swagger's annotation @Api, or packages containing those classes can be configured here, using ; as the delimiter. |
schemes |
The transfer protocol of the API. Values MUST be from the list: "http", "https", "ws", "wss". |
host |
The host (name or ip) serving the API. This MUST be the host only and does not include the scheme nor sub-paths. It MAY include a port. The host does not support path templating. |
basePath |
The base path on which the API is served, which is relative to the host. The value MUST start with a leading slash (/). The basePath does not support path templating. |
descriptionFile |
A Path to file with description to be set to Swagger Spec 2.0's info Object |
info required |
The basic information of the api, using same definition as Swagger Spec 2.0's info Object |
securityDefinitions |
You can put your security definitions here, see more details below |
security |
A declaration of which security schemes are applied for the API as a whole. security requirement see more details below |
templatePath |
The path of a handlebars template file, see more details below. |
outputPath |
The path of the generated static document, not existed parent directories will be created. If you don't want to generate a static document, just don't set it. |
outputFormats |
The format types of the generated swagger spec. Valid values are json, yaml or both (as a list, e.g. ['json']). The json format is default. |
shouldSortArrays |
JSON arrays will be sorted instead of being written in the order of appearance. Default is false. |
swaggerDirectory |
The directory of generated swagger.json file. If null, no swagger.json will be generated. |
swaggerFileName |
The filename of generated filename.json file. If null, swagger.json will be generated. |
swaggerApiReader |
If not null, the value should be a full name of the class extending com.github.kongchen.swagger.docgen.reader.ClassSwaggerReader. This allows you to flexibly implement/override the reader's implementation. Default is com.github.kongchen.swagger.docgen.reader.JaxrsReader. More details below |
attachSwaggerArtifact |
If enabled, the generated swagger.json file will be attached as a gradle artifact. The swaggerFileName will be used as an artifact classifier. Default is false. |
modelSubstitute |
The model substitute file's path, see more details below |
typesToSkip |
Nodes of class names to explicitly skip during parameter processing. More details below |
apiModelPropertyAccessExclusionsList |
Allows the exclusion of specified @ApiModelProperty fields. This can be used to hide certain model properties from the swagger spec. More details below |
jsonExampleValues |
If true, all example values in @ApiModelProperty will be handled as json raw values. This is useful for creating valid examples in the generated json for all property types, including non-string ones. |
modelConverters |
List of custom implementations of io.swagger.converter.ModelConverter that should be used when generating the swagger files. More details below |
excludePattern |
Regex of files that will be excluded from the swagger documentation. The default is .*\\.pom so it ignores all pom files. |
tagStrategy |
Default no. class use class name if no tags are set to group operations specific to controller. (currently only springmvc) |
expandSuperTypes |
Default true. You can skip the scan of super types (parent class, interfarce) |
If you'd like to generate a template-driven static document, such as markdown or HTML documentation, you'll need to specify a handlebars template file in templatePath.
The value for templatePath supports 2 kinds of path:
-
Resource in classpath. You should specify a resource path with a classpath: prefix. e.g:
classpath:/markdown.hbsclasspath:/templates/hello.html
-
Local file's absolute path. e.g:
${project.rootDir}/src/main/resources/markdown.hbs${project.rootDir}/src/main/resources/template/hello.html
There's a standalone project for the template files, fetch them and customize it for your own project.
There're 3 types of security definitions according to Swagger Spec: basic, apiKey and oauth2.
You can define multi definitions here, but you should fully follow the spec.
You can define a basic definition like this:
securityDefinition {
// `name` can be used refer to this security schemes from elsewhere
name = 'MyBasicAuth'
type = 'basic'
}You can also define a ApiKey definition like this:
swagger {
apiSource {
...
securityDefinition {
// `name` can be used refer to this security schemes from elsewhere
name = 'ApiKeyAuth'
type = 'apiKey'
// The location of the API key. Valid values are "query" or "header".
keyLocation = 'header'
// The name of the header
keyName = 'X-API-Key'
}
}
}You can also define a Oauth2 definition like this:
swagger {
apiSource {
...
securityDefinition {
// `name` can be used refer to this security schemes from elsewhere
name = 'OAuth2Authentication'
type = 'oauth2'
// The flow used by the OAuth2 security scheme
flow = 'accessCode'
authorizationUrl = 'https://somewhere.com/authorization'
tokenUrl = 'https://somewhere.com/token'
scope {
name = 'read:model'
description = 'Read the details of the model'
}
}
}
}It is also possible to define several definitions in a json file and specify the json path like this:
securityDefinition {
json = 'securityDefinition.json'
}Alternatively, specify the absolute file path to the json definition file:
securityDefinition {
json = "${project.projectDir}/securityDefinition.json"
}The securityDefinition.json file should also follow the spec, one sample file like this:
{
"api_key": {
"type": "apiKey",
"name": "api_key",
"in": "header"
},
"petstore_auth": {
"type": "oauth2",
"authorizationUrl": "http://swagger.io/api/oauth/dialog",
"flow": "implicit",
"scopes": {
"write:pets": "modify pets in your account",
"read:pets": "read your pets"
}
}
}Note: It is only possible to define the OAuth2 type in a json file and not directly in the gradle configuration.
Allows to set a security requirement on the whole API. This can be done with multiple security requirements applied as AND or OR values. See https://swagger.io/docs/specification/2-0/authentication/ The key of the security requirement has to match a name from a securityDefinition.
security = [ [ ApiKeyAuth : [] ] ]Use BasicAuth with ApiKey or OAuth2 with given scopes (basic(name: MyBasicAuth) && apiKey(name: MyApiKey)) || oauth2(name: MyOAuth2)
security = [ [ MyBasicAuth : [], MyApiKey : [] ], [ MyOAuth2 : [ 'scope1', 'scope2' ] ] ]You can instruct swagger-gradle-plugin to use a custom swagger api reader rather than use the default by adding the following to your build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.custom:swagger-api-reader:1.0.0'
}
}
...
swagger {
apiSource {
...
swaggerApiReader = [ 'com.custom.swagger.ApiReader' ]
}
}It is important to note that the class has to be available in the buildscript's classpath.
Throughout the course of working with Swagger, you may find that you need to substitute non-primitive objects for primitive objects. This is called model substituion, and it is supported by swagger-gradle-plugin. In order to configure model substitution, you'll need to create a model substitute file. This file is a simple text file containing n lines, where each line tells swagger-gradle-plugin to substitutes a model class with the supplied substitute. These two classes should be seperated by a colone (:).
com.foo.bar.PetName : java.lang.String
The above model substitution configuration would tell the plugin to substitute com.foo.bar.PetName with java.lang.String. As a result, the generated swagger.json would look like this ...
"definitions" : {
"Pet" : {
"properties" : {
...
"petName" : {
"type" : "string"
}
...
}
}... instead of like this:
"definitions" : {
"Pet" : {
"properties" : {
...
"petName" : {
"$ref" : "#/definitions/PetName"
}
...
}
}The model substitution file will be read by getClass().getResourceAsStream, so please note the path you configured.
You can instruct swagger-gradle-plugin to skip processing the parameters of certain types by adding the following to your build.gradle:
// TODO: Not fully supported yet
typesToSkip = [
'com.foobar.skipper.SkipThisClassPlease',
'com.foobar.skipper.AlsoSkipThisClassPlease'
]You can instruct swagger-gradle-plugin to use a custom model converter rather than use the default by adding the following to your build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.custom:model-converter:1.0.0'
}
}
...
swagger {
apiSource {
...
modelConverters = [ 'com.custom.model.Converter' ]
}
}It is important to note that the class has to be available in the buildscript's classpath.
If you'd like to exclude certain @ApiModelPropertys based on their access values, you may do so by adding the following as a child node of apiSource in your build.gradle:
apiModelPropertyAccessExclusionsList = [
'secret-property'
]The above setting would prevent internalThing from appearing in the swagger spec output, given this annotated model:
...
@ApiModelProperty(name = "internalThing", access = "secret-property")
public String getInternalThing() {
return internalThing;
}
...Note: In order to use apiModelPropertyAccessExclusionsList, you must specify both the name and access fields of the property you wish to exclude.
To generate the swagger documentation, you need to run ./gradlew generateSwaggerDocumentation.
N.B In previous versions (< 0.1.0) the task was swagger, but this caused a conflict with another plugin, swagger-codegen, (issue #8).
To skip generating the swagger documentation, you need to include the property swagger.skip (e.g. ./gradlew clean build -Pswagger.skip)
You can instruct swagger-gradle-plugin to deploy the generated swagger.json by adding the following to your build.gradle:
attachSwaggerArtifact = trueThe above setting attaches the generated file to Gradle for install/deploy purpose with swaggerDirectory's name as classifier and the outputFormat as type.
Please note that when using the maven-publish plugin instead of the maven plugin, the classifier must be specified in the configuration as it uses a different mechanism for the classifier. This is especially important when using multiple apiSource closures. Example:
publishing {
publications {
maven(MavenPublication) {
artifact source: "${swaggerDirectory}/publicApiSwagger.json", classifier: 'publicApiSwagger'
artifact source: "${swaggerDirectory}/privateApiSwagger.json", classifier: 'privateApiSwagger'
}
