Element template generator feedback

[chillleader]

This issue is a place for general feedback from using one of our element template generators. If you have a small suggestion or a minor bug report, it's a good candidate to be added to this list.

If you have a suggestion, please add a comment below and we'll add it into the list.

Note that the suggestions here should have a limited scope (e.g. add a field to the annotation). All action items here don't have a high priority and will be picked up based on the available capacity. If you have a request with a bigger scope or a high priority, please open a separate issue. If the context is too complex to be expressed in 2 sentences, please open a separate issue as well.

Java annotation-based element template generator

• Raise a warning/error if @TemplateProperty references a group that is not defined in @ElementTemplate.propertyGroups. Currently such properties are silently ignored.

• Allow overriding dropdown choice labels by annotating the corresponding enum constants (to avoid a more verbose configuration via @TemplateProperty.dropdownChoices

• Support language attribute on properties (for example: graphql) for enhanced language support of the code editor: chore(graphql): Use element template generator for GraphQL outbound c… #1903 (comment)

• based on this support request:

  • it would be great if the files io.camunda.connector.api.outbound.OutboundConnectorFunction and io.camunda.connector.api.inbound.InboundConnectorExecutable under META-INF/services were also generated from the classes listed in connectorClasses. Depending on the connector type, the class name must be written in one of the two files.
  •  Documentation around template generators in our offical documentation page (What is it, when to use it , how to use it, where to find it, what is supported / What not? https://jira.camunda.com/browse/SUPPORT-20138

• Allow configuring binding name prefix for nested properties

• Connector generation cannot be started on Windows, probably because we exceed the maximum command line length which is 8191 characters on windows. (when setting the CLASSPATH variable) Probable solution: https://stackoverflow.com/a/52585324/4109477

• Support the inputDataClass on the OutboundConnector annotation: https://github.com/camunda/team-connectors/issues/959

• Support generation of constraints based on the input property type (comment below)

ConGen tool / CLI generators - OpenAPI, Postman

• Support API key authentication for OpenAPI generator
