How do I install JQuery into my web app using Maven?

Question

I am looking at using Maven 3 for some web development. I know how to use maven to resolve java based jar files. How do I use maven to resolve JavaScript dependencies for example I want to have maven automatically put jquery in my webapp/js folder?

Is it possible to do transative JavaScript dependencies with Maven 3?

Solution 1

You could create your own "war" that has jquery in it on the path you specified.

Afterwards add that war to your real web application. Maven should merge it. I think it was called somehting like "processing overlay".

I'm using the same for some GWT application where the javascript is generated by a maven plugin and it works well.

Solution 2

Perhaps WebJars can help you:

WebJars are client-side web libraries (e.g. jQuery & Bootstrap) packaged into JAR (Java Archive) files.

• Explicitly and easily manage the client-side dependencies in JVM-based web applications
• Use JVM-based build tools (e.g. Maven, Gradle, & SBT) to download your client-side dependencies
• Know which client-side dependencies you are using
• Transitive dependencies magically appear

Caveat: WebJars does not put the jquery files in the webapp/js folder. Please read documentation to see how it is used with some popular frameworks.

Solution 3

Try adding this to your pom.xml file. It worked for me :

<dependency>
    <groupId>com.efsavage.jquery</groupId>
    <artifactId>jquery-maven</artifactId>
    <version>1.7.2</version>
</dependency>

This library gives you a way to drop jQuery into your project as a Maven dependency, which means you don't have to include these third party files in your own source control.

How do I add the war to my project using maven? Can I make transitive JavaScript dependencies?

[Udo Held]

You add it as a dependency of type war. Before you can add it to your other projects you need a web project with jquery in it and install it to your repository.

That link indeed explains the behavior I was refering to. I've looked at it some time ago. :)

hosting from a CDN is not appropriate for this application, the application must be self contained with everything that it needs inside of it

Hello, how do you use it in your JSP after you have added the dependency?
