Apache StreamPipes Maven Plugin

Description

The Apache StreamPipes is an internal developer plugin which eases the generation of documentation for adapters and pipeline elements.

The plugin generates documentation files which can be integrated into the UI.

Usage

The streampipes-maven-plugin can either be started from the command line or embedded into a project's pom.

Prerequisites

The plugin must be started from a module which contains an Init class which inherits StreamPipesExtensionsServiceBase. By default, the goal runs in the package phase.

Command line

# Switch to a directory containing StreamPipes extensions and an Init class, e.g., extensions-all-jvm

mvn streampipes:extract-docs -DinitClass=org.apache.streampipes.extensions.all.jvm.AllExtensionsInit

Inclusion in pom file

</plugin>

• Replace the version with the current development version.
• Replace the initClass with the module's init class.
• The dependency to RocketMQ is only needed for modules containing the RocketMQ sink and can be omitted otherwise.

Output

The plugin creates a new folder docs in the module's target directory.

The folder includes:

• An img folder which has a subdirectory for each extension (named by the appId) containing the icon.
• A pe folder which has a subdirectory for each extension (named by the appId) containing the documentation.md file, which has been rewritten to match the requirements of the Docusaurus Markdown parser.
• An updated sidebar.json file containing the sidebar, which is downloaded from the streampipes-website repo on branch dev and updated with the current set of extensions.
