Class GitWorkflowRepository

  • All Implemented Interfaces:
    org.copperengine.core.common.WorkflowRepository, org.copperengine.management.FileBasedWorkflowRepositoryMXBean, org.copperengine.management.WorkflowRepositoryMXBean
    public class GitWorkflowRepository
extends org.copperengine.core.wfrepo.FileBasedWorkflowRepository
implements org.copperengine.core.common.WorkflowRepository, org.copperengine.management.FileBasedWorkflowRepositoryMXBean
    Extension of FileBasedWorkflowRepository, that adds an observer of a git repository. The setBranch(String) branch in setOriginURI(String) is pulled for changes. The changes are applyed online. The interval setCheckIntervalMSec(int) is also used in the FileBasedWorkflowRepository. This class enables a lightweight CI/CD pipeline using git repositories only for changes in workflows. Changes outside the workflows are not in scope of this pipeline.
