In this article, you’ll learn how to create a Liferay WAR core Ext project. To create a WAR core Ext project via the command line using Blade CLI or Maven, use one of the commands with the following parameters:
blade create -t war-core-ext projectName
or
mvn archetype:generate \
-DarchetypeGroupId=com.liferay \
-DarchetypeArtifactId=com.liferay.project.templates.war.core.ext \
-DartifactId=[projectName] \
-DliferayVersion=7.2
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 war-core-ext
. Suppose you want to
create a WAR core Ext project called my-war-core-ext-project
. You could run
the following command to accomplish this:
blade create -t war-core-ext my-war-core-ext-project
or
mvn archetype:generate \
-DarchetypeGroupId=com.liferay \
-DarchetypeArtifactId=com.liferay.project.templates.war.core-ext \
-DgroupId=com.liferay \
-DartifactId=my-war-core-ext-project \
-DliferayVersion=7.2
After running the Blade command above, your project’s folder structure looks like this:
my-war-core-ext-project
gradle
wrapper
gradle-wrapper.jar
gradle-wrapper.properties
src
extImpl

META-INF
ext-model-hints.xml

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 WAR Ext project is functional and is deployable to a Liferay DXP instance. To build upon the generated project, modify the project by adding logic and additional files to the folders outlined above. Deploying WAR Ext projects is only supported for limited use cases; it is recommended to leverage provided extension points offered in Liferay DXP. You can visit the Customization with Ext section for info on how to do this.
