Creating applications is fun when you have the right tools. Here are some key ingredients:
- Rich templates for stubbing out projects
- Extensible build environments that offer state-of-the-art plugins
- Deployment and runtime management tools
- Application upgrade automation
Liferay Workspace (Workspace) boils over with all these things! It’s a Gradle-based development environment that integrates with Liferay Developer Studio and can be used in conjunction with other IDEs, such as a “vanilla” Eclipse, IntelliJ, and NetBeans. You can extend Workspace’s Gradle environment with community-developed (or home-grown) plugins for testing, code coverage analysis, and more.
Workspace comes with Blade CLI: a command line tool for creating and deploying modules, managing the runtime environment, and more. It provides all kinds of module templates, to create modules for developing in any Gradle environment.
Liferay’s tools also streamline the application upgrade process. Liferay Developer Studio’s Upgrade Planner adapts traditional plugins to Liferay DXP 7.0 APIs. Liferay’s Liferay Theme Generator migrates themes and layout templates to the new NodeJS-based environment and adapts them to Liferay DXP 7.0.
Liferay DXP offers you more with Maven too. The archetype Liferay Project Templates Workspace lets you develop in Liferay Workspace using Maven. Liferay DXP 7.0’s’ lean artifacts and new project archetypes and Maven plugins make Liferay DXP development with Maven easier than ever.
Here are the tooling improvement topics:
- Moving from the Plugins SDK to Liferay Workspace
- Developing modules with Liferay Workspace
- What’s new in Liferay DXP for Maven Users
- Using other build systems and IDEs
The Liferay Plugins SDK is deprecated as of Liferay DXP 7.0. You can continue developing on it, but should plan to eventually move to a new environment. Liferay Workspace succeeds the Plugins SDK as Liferay’s opinionated development environment. You should use it if you’re not using an alternative build system like Gradle or Maven.
Here are Workspace’s key features:
- Module and component templates
- Sample projects
- Portal server configurations
- Folder structure flexibility
- Commands to migrate plugins, install Liferay DXP bundles, and start/stop Portal instances
The plugin upgrade tutorials later in this series show how Liferay Developer Studio automatically adapts existing plugins to Liferay DXP 7.0. There’s also a tutorial that demonstrates how you can optionally migrate traditional plugins to Workspace.
Here’s an example Workspace folder structure:
Here’s the Workspace anatomy:
bundles/(generated) → default folder for Liferay DXP bundles
configs/→ holds Portal server configurations
gradle/→ holds the Gradle wrapper files
modules/→ holds module projects
plugins-sdk/(generated) → holds plugins from previous releases
themes/→ holds NodeJS-based theme projects
wars/(generated) → holds traditional web application projects
build.gradle→ common Gradle build file
gradle.properties→ specifies the Portal server configuration and project locations
gradlew / gradlew.bat→ executes the Gradle command wrapper
pom.xml(only in Workspaces generated by Maven) → common Maven build file
settings.gradle→ applies plugins to the Workspace and configures its dependencies
Workspace module, theme, and war projects use the same Portal server configurations. Developers can create configurations for module development, user acceptance testing, production, and more.
Each subfolder under
configs holds a Portal server configuration defined by
portal-ext.properties file. Gradle property
liferay.workspace.environment in Workspace’s
specifies the configuration to use.
Other Gradle properties let you set root locations for the Liferay DXP bundle, modules, themes, and a Plugins SDK.
|Name of a
configs subfolder holding the Portal server configuration to use
|Liferay DXP bundle root folder
|Module projects root folder
|Plugins SDK root folder
|Theme projects root folder
Workspace has Gradle tasks equivalent to the Plugins SDK Ant targets.
|Plugins SDK Ant Target
|Workspace Gradle Task
|Builds CSS files
|Translates language keys using Language Builder
|Runs Service Builder
|Deletes all build outputs
|Installs the current module to Liferay DXP’s module framework
|Compiles the project and packages it as a JAR file
|Assembles project output
Other Workspace Gradle tasks provide additional functionality.
|Workspace Gradle Task
|Lists the project’s components
|Lists the project’s declared dependencies
|Downloads and installs a Liferay DXP bundle
|Lists the project’s configuration model
Next, learn how Workspace facilitates module development.
Workspace is a great Liferay module development environment because of these features:
- Templates that bootstrap module creation
- Gradle and Maven build systems for managing dependencies and assembling modules
- Module deployment and runtime management capabilities
Blade CLI (Blade), which is a part of Workspace, has over twenty templates for Gradle-based module projects–and more are being added. The templates stub out classes and resource files for you to fill in with business logic and key information.
Here are some of the template’s names:
- Content Targeting Report
- Content Targeting Rule
- Content Targeting Tracking Action
- Control Menu Entry
- MVC Portlet
- Panel App
- Portlet Configuration Icon
- Portlet Provider
- Portlet Toolbar Contributor
- Service Builder
- Service Wrapper
- Simulation Panel Entry
- Template Context Contributor
Blade creates modules based on these templates.
For example, the following Blade command creates a Liferay MVC Portlet module
blade create -t mvc-portlet -p com.liferay.docs.mymodule -c MyMvcPortlet my-module
Liferay Developer Studio’s module project wizard creates Workspace modules from the templates too.
Liferay Developer Studio’s component wizard facilitates creating component classes for portlets, service wrappers, Struts actions, and more.
Building and deploying modules in a Workspace is a snap using Liferay
Workspace uses BndTools to generate each module’s OSGi headers in a
META-INF/MANIFEST.MF file. Workspace deploy modules to the OSGi container
using Felix File Install commands.
Liferay Developer Studio lets you deploy modules by dragging them onto your Portal server.
In a terminal, you can deploy modules using Blade’s
deploy command. For
example, the following command deploys the current module and
“watches” for module changes to redeploy automatically.
blade deploy -w

Next, you’ll learn new features for developing on Liferay DXP using Maven.
Liferay DXP 7.0 fully supports Maven development and offers several new and improved features:
- Liferay Workspace for Maven
- New archetypes
- New Maven plugins
- More granular dependency management
The new archetype Liferay Project Templates Workspace generates a Liferay Workspace that includes a POM file for developing in Workspace using Maven. You can develop modules and themes in the Workspace subfolders.
Liferay DXP 7.0 provides many new Maven archetypes for various Liferay module projects. There are over twenty-five Maven archetypes for Liferay DXP 7.0, and more are in development. Here are some popular ones:
- Configuration Icons
- Menu Buttons
- Service Builder
Liferay’s Maven archetypes cover many different Liferay frameworks and service types. These make Maven a first-class tool for creating Liferay modules and themes. Visit the Generating New Projects Using Archetypes tutorial to learn more about Liferay’s Maven archetypes and how to use them.
Liferay also provides several new and updated Maven plugins that simplify the build process. The following plugins build style sheets, services, and themes respectively:
Liferay DXP 7.0’s modularity provides a more granular dependency management
experience. You no longer need to depend on
portal-kernel) for everything. For example, to use Liferay’s Wiki
framework, you need only depend on the Wiki module. You set dependencies on
concise modules that provide the functionality you want without inheriting extra
Liferay’s new Workspace environment, Maven archetypes, Maven plugins, and streamlined modules make developing on Liferay DXP easier than ever. To learn more, see the Maven tutorials.
Liferay DXP is tool agnostic–you can use whatever tools you like to develop on it. You can use any IDE and even use Gradle, Bnd, or BndTools if you don’t want to use Workspace. The drawback is you lose the Liferay-specific project templates that you get with Blade and Workspace.
Blade lets you create modules to develop anywhere, not only in Liferay Workspace.
Here are some new Gradle features Liferay provides that are independent of Workspace:
- Liferay’s Gradle plugins
- Buildship plugins in Liferay Developer Studio
- Liferay Developer Studio’s new Gradle views for developing modules and working with Gradle tasks
Liferay has worked hard to make Liferay DXP IDE-agnostic. There are Liferay module developers who use IntelliJ and some enjoy using NetBeans.
Finally, you can copy and modify Liferay sample projects to serve as templates in place of the Blade templates. They’re available for these build systems:
- Liferay’s Gradle environment based on the
Liferay’s approach to tooling has vastly improved for Liferay DXP 7.0. Our tools help you upgrade to Liferay DXP 7.0, continue developing traditional plugins the way you have been, and migrate to optimal development environments. Liferay Workspace and the improved Maven support facilitate module development. And developing on Liferay DXP using other tools is easier than ever. Your tool options are wide open.
