The Field Adder Transforms allow you to add one or more fields to incoming records.
To build your plugins:
mvn clean package -DskipTests
The build will create a .jar and .json file under the target directory.
These files can be used to deploy your plugins.
The CDAP UI displays each plugin property as a simple textbox. To customize how the plugin properties
are displayed in the UI, you can place a configuration file in the widgets directory.
The file must be named following a convention of [plugin-name]-[plugin-type].json.
See Plugin Widget Configuration for details on the configuration file.
The UI will also display a reference doc for your plugin if you place a file in the docs directory
that follows the convention of [plugin-name]-[plugin-type].md.
When the build runs, it will scan the widgets and docs directories in order to build an appropriately
formatted .json file under the target directory. This file is deployed along with your .jar file to add your
plugins to CDAP.
You can deploy your plugins using the CDAP CLI:
> load artifact <target/plugin.jar> config-file <target/plugin.json>
For example, if your artifact is named 'my-plugins-1.0.0':
> load artifact target/my-plugins-1.0.0.jar config-file target/my-plugins-1.0.0.json
