Action Executor sample code does not compile for Liferay Portal 7.4.3.132

2025-07-18T19:39:26Z

Hello Liferay Community Admin,

the online Liferay Developer guide contains an invalid Action Executor sample project for the Creating an Action Executor page.

The Creating an Action Executor page is available at

https://learn.liferay.com/w/dxp/low-code/workflow/developer-guide/creating-an-action-executor

The sample project referenced on the page is available at

https://resources.learn.liferay.com/examples/liferay-e5c9.zip

The sample project contains code and configuration intended for Liferay Portal 7.4 GA132

e.g.

% cat gradle.properties
liferay.workspace.product=portal-7.4-ga132
liferay.workspace.target.platform.version=7.4.3.132

However, attempting to build the sample project will trigger a compilation error, due to a mismatch in the WorkflowDefinitionManager#deployWorkflowDefinition usage.

e.g.

% ./gradlew clean build

> Task :stopDockerContainer
Stopping container with ID 'liferay-e5c9-liferay'.
No container with ID 'liferay-e5c9-liferay' running.

> Task :removeDockerContainer
Removing container with ID 'liferay-e5c9-liferay'.
No container with ID 'liferay-e5c9-liferay' found.

> Task :cleanDockerImage
Removing image with ID 'liferay-e5c9-liferay:7.4.3.132-ga132'.
No image with ID 'liferay-e5c9-liferay:7.4.3.132-ga132' found.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.5/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Is there an alternative branch for this sample project which contains a valid set of code and configuration for Liferay Portal 7.4 GA132?

Please review and advise.

Thank you,
