Portlet Toolbar Contributor Template

In this article, you’ll learn how to create a Liferay portlet toolbar contributor as a Liferay module. To create a portlet toolbar contributor entry via the command line using Blade CLI or Maven, use one of the commands with the following parameters:

blade create -t portlet-toolbar-contributor [-p packageName] [-c className] projectName

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.portlet.toolbar.contributor \
    -DartifactId=[projectName] \
    -Dpackage=[packageName] \
    -DclassName=[className] \
    -DliferayVersion=7.1

You can also insert the -b maven parameter in the Blade command to generate a Maven project using Blade CLI.

The template for this kind of project is portlet-toolbar-contributor. Suppose you want to create a portlet toolbar contributor project called my-portlet-toolbar-contributor with a package name of com.liferay.docs.portlet.toolbar.contributor and a class name of SamplePortletToolbarContributor. You could run the following command to accomplish this:

blade create -t portlet-toolbar-contributor -p com.liferay.docs -c Sample my-portlet-toolbar-contributor

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.portlet.toolbar.contributor \
    -DgroupId=com.liferay \
    -DartifactId=my-portlet-toolbar-contributor \
    -Dpackage=com.liferay.docs \
    -Dversion=1.0 \
    -DclassName=Sample \
    -Dauthor=Joe Bloggs \
    -DliferayVersion=7.1

After running the Blade command above, your project’s directory structure would look like this

  • my-portlet-toolbar-contributor
    • gradle
      • wrapper
        • gradle-wrapper.jar
        • gradle-wrapper.properties
    • src
      • main
        • java
          • com/liferay/docs/portlet/toolbar/contributor
            • SamplePortletToolbarContributor.java
        • resources
          • content
            • Language.properties
    • bnd.bnd
    • build.gradle
    • gradlew

The Maven-generated project includes a pom.xml file and does not include the Gradle-specific files, but otherwise, appears exactly the same.

The generated module is functional and is deployable to a Liferay Portal instance. To build upon the generated app, modify the project by adding logic and additional files to the folders outlined above. This generated project, by default, creates a new button on the Hello World portlet’s toolbar. You can visit the portlet-toolbar-contributor sample project for a more expanded sample of a portlet toolbar contributor.
