Run web application with Maven Jetty Plugin

In this tutorial, I will introduce to all of you a Maven plugin, which can help us run a web application in Jetty with some simple configurations. This is Maven Jetty Plugin.

First of all, we need a web project using Maven for example.

I use Spring Tool Suite to create an example Maven project for this tutorial.

If you don’t know how to create a web project in Spring Tool Suite IDE, you can look at this tutorial.

Our project structure as below:

Now, I will add Maven Jetty Plugin into our project. Currently, Jetty has 3 versions:

• A version running with Java 8 supports JavaEE 8, Servlet 3.1
• A version running with Java 11 supports JakartaEE 8, Servlet 4.0
• And a version running with Java 11 supports JakartaEE 9, Servlet 4.1

I am using Java 8 for this example so I will use Jetty to run with this Java version.

OK, now we can run our application.

Let right-click on the project or the pom.xml file, then choose Run As and select Maven build…

The window Run Configurations will appear, let enter clean jetty:run into field Goals as below:

After that press Run button, Maven will build our project and run it on Jetty server with default port is 8080, root context path will be “/”, which means you only need to run http://localhost:8080 then you can see the web page.

Result:

To change the root context path of our web application, you can add more configuration for Maven Jetty Plugin in the pom.xml file as below:

Run again, result as below:

If you want to change the port number, you also can add more configuration for Maven Jetty Plugin as below:
