Chapter 58. Managing custom tasks in Business Central Custom tasks (work items) are tasks that can run custom logic. You can customize and reuse custom tasks across multiple business processes or across all projects in Business Central. You can also add custom elements in the designer palette, including name, icon, sub-category, input and output parameters, and documentation. Red Hat Process Automation Manager provides a set of custom tasks within the custom task repository in Business Central. You can enable or disable the default custom tasks and upload custom tasks into Business Central to implement the tasks in the relevant processes. Note Red Hat Process Automation Manager includes a limited set of supported custom tasks. Custom tasks that are not included in Red Hat Process Automation Manager are not supported. Procedure In Business Central, click in the upper-right corner and select Custom Tasks Administration . This page lists the custom task installation settings and available custom tasks for processes in projects throughout Business Central. The custom tasks that you enable on this page become available in the project-level settings where you can then install each custom task to be used in processes. The way in which the custom tasks are installed in a project is determined by the global settings that you enable or disable under Settings on this Custom Tasks Administration page. Under Settings , enable or disable each setting to determine how the available custom tasks are implemented when a user installs them at the project level. The following custom task settings are available: Install as Maven artifact : Uploads the custom task JAR file to the Maven repository that is configured with Business Central, if the file is not already present. Install custom task dependencies into project : Adds any custom task dependencies to the pom.xml file of the project where the task is installed. Use version range when installing custom task into project : Uses a version range instead of a fixed version of a custom task that is added as a project dependency. Example: [7.16,) instead of 7.16.0.Final Enable or disable (set to ON or OFF ) any available custom tasks as needed. Custom tasks that you enable are displayed in project-level settings for all projects in Business Central. Figure 58.1. Enable custom tasks and custom task settings To add a custom task, click Add Custom Task , browse to the relevant JAR file, and click the Upload icon. If a class implements a WorkItemHandler , you can replace annotations with a .wid file by adding the file to Business Central separately. Optional: To remove a custom task, click remove on the row of the custom task you want to remove and click Ok to confirm removal. After you configure all required custom tasks, navigate to a project in Business Central and go to the project Settings Custom Tasks page to view the available custom tasks that you enabled. For each custom task, click Install to make the task available to the processes in that project or click Uninstall to exclude the task from the processes in the project. If you are prompted for additional information when you install a custom task, enter the required information and click Install again. The required parameters for the custom task depend on the type of task. For example, rule and decision tasks require artifact GAV information (Group ID, Artifact ID, Version), email tasks require host and port access information, and REST tasks require API credentials. Other custom tasks might not require any additional parameters. Figure 58.2. Install custom tasks for use in processes Click Save . Return to the project page, select or add a business process in the project, and in the process designer palette, select the Custom Tasks option to view the available custom tasks that you enabled and installed: Figure 58.3.
