swaggerhub-maven-plugin

A simple Maven plugin to access SwaggerHub hosting of OpenAPI/Swagger definitions within a Maven build process, using the SwaggerHub API.

Features

Download/upload API definitions from/to SwaggerHub Cloud.
Upload multiple API definitions at once.
Authenticate with an API key for restricted operations (for example, to download private definitions).
Supports YAML and JSON format for API definitions.
Automatically provision an SCM Integration to update source control with changes made to definitions.

Example use cases

The usage pattern depends on whether you use the code-first or design-first approach.

Code-first

Code your API implementation.
Automatically generate the API definition from the source code, for example, using Swagger Core annotations and Swagger Maven plugin. See the Swagger Core wiki to learn more.
Upload the generated API definition to SwaggerHub using the SwaggerHub Maven plugin.

Design-first

Write your API definition on SwaggerHub.
Download the API definition using the SwaggerHub Maven plugin.
Pass the API definition to another Swagger tool, for example:
- Use Swagger Codegen Maven plugin to generate API server and client code.
- Use Swagger Inflector to automatically wire up the API definition to the implementation and provide out-of-the-box mocking.

Goals

SwaggerHub Maven plugin provides two goals, download and upload.

download

This goal downloads an API definition from SwaggerHub to a local file as part of the default Maven build lifecycle.

    <plugin>
        <groupId>io.swagger</groupId>
        <artifactId>swaggerhub-maven-plugin</artifactId>
        <version>1.0.4</version>
        <executions>
            <execution>
                <phase>generate-resources</phase>
                <goals>
                    <goal>download</goal>
                </goals>
                <configuration>
                    <api>PetStoreAPI</api>
                    <owner>jsfrench</owner>
                    <version>1.0.0</version>
                    <outputFile>target/petStoreAPI.json</outputFile>
                </configuration>
            </execution>
        </executions>
    </plugin>

Parameters

Parameter	Description	Required?	Default
`api`	API name (case-sensitive)	yes	-
`owner`	API owner (case-sensitive)	yes	-
`version`	API version (case-sensitive)	yes	-
`outputFile`	API definition will be saved to this file	yes	-
`token`	SwaggerHub API key, required to access private definitions	no	-
`format`	API definition format, `json` or `yaml`	no	`json`
`host`, `protocol`, `port`	Reserved for future use	no

upload

This goal creates or updates one or more API definitions on SwaggerHub. All definitions are saved in the owner account (organization or user), and the token owner must have permissions to create and update definitions in this account.

Additionally, there is the option of provisioning a SwaggerHub SCM integration which will allow changes made in SwaggerHub to be pushed back to source control.

There are two uploadType modes:

inputFile - Upload a single API definition.
directory - Upload one or more definitions from the specified definitionDirectory, optionally filtered by a regular expression.

Parameters

Common parameters:

Parameter	Description	Required?	Default
`uploadType`	Possible values: `inputFile` - upload a single API definition; `directory` - upload multiple definitions stored in a directory	yes	-
`owner`	The account name (case-sensitive) to upload the definitions to	yes	-
`token`	SwaggerHub API key. The API key owner must have permissions to create and update definitions in the `owner` account	yes	-
`isPrivate`	Specifies whether the uploaded APIs will be made public (`false`) or private (`true`)	no	`false`
`skipFailures`	Specifies whether a build should fail when errors are encountered	no	false

Additional parameters for uploadType=inputFile:

Parameter	Description	Required?	Default

`format`	API definition format, `json` or `yaml`	no	`json`

Additional parameters for uploadType=directory:

Parameter	Description	Required?	Default
`definitionDirectory`	Directory containing the definitions to be uploaded to SwaggerHub. Note that subdirectories are not included in the upload.	yes	-
`definitionFileNameRegex`	Regular expression that specifies the files to be uploaded. This regex matches against file names without extensions. If not specified, all .json, .yaml and .yml files from the `definitionDirectory` will be uploaded.	no	-

Additional parameters for SCM integration provisioning:

`branch`	The repository branch to push SwaggerHub changes to	no	-	SWAGGERHUB

Multi-upload considerations

When using uploadType=directory, all definitions to be uploaded must be stored in the definitionDirectory (the directory itself, not subdirectories). The plugin only processes files with the following extensions: .yaml, .yml, .json. Files with other extensions are ignored. The files must be valid JSON or YAML files.

By default, the plugin uploads all JSON and YAML files from the specified directory, but you can use definitionFileNameRegex to narrow down the files to be uploaded. The regular expression matches against file names without file extensions. The matching is partial unless the regex contains the ^ (beginning of line) and $ (end of line) anchors. To make the matching case-insensitive, include (?i) at the beginning, or (?iu) for Unicode-aware case-insensitive matching. Examples:

acme matches file names that contain "acme" in lower case.
^acme matches file names that begin with "acme" in lower case.
^(?i)acme matches file names that begin with "acme" in any letter case.

API names and versions are generated by parsing the info section of the definitions. The info section must include non-empty title and version keys.

API names are generated based on the info.title, with characters other than A-Za-z0-9_ replaced with underscores. For example, a definition with title: Sample API will be saved under the name Sample_API on SwaggerHub.
API versions are extracted from the info.version key. If this API version already exists, it will be updated with the new definition (unless the version is published - in this case the update will be rejected).

If an error occurs while uploading any definition, the build will fail and subsequent definitions will not be uploaded.

SCM integration provisioning considerations

Supported SCM's include: GITHUB, BITBUCKET
Care should be taken when specifying SCM parameters. Validation does not take place prior to making the request to SwaggerHub and issues can arise due to incorrectly configured integrations
Use only the parameters that are required for the SCM of your choice. For example BITBUCKET relies on scmUsername and scmPassword; if an scmToken is also included, the Bitbucket integration will attempt to authenticate with the token. This is not possible and will cause integration errors.
BITBUCKET can use app passwords to authenticate. App passwords are substitute passwords for a user account which you can use for scripts and integrating tools to avoid putting your real password into configuration files. App password permissions required are:
- Account : Email, Read
- Repositories : Read, Write

Documentation on how to generate an app password can be found here.
