In the previous recipe, we learned how to use SBT to create and run a Lift application. Now I will show you how to set up and run a Lift application using Maven, which is another build tool.
If you don't have Maven installed and configured on your computer, go to http://maven.apache.org/download.cgi, download Maven 3.1.0, and follow the installation instructions.
We will use a Maven archetype that will create a ready-to-use Lift application for us.
Open a cmd window and run the following command:
mvn archetype:generate ^ -DarchetypeGroupId=net.liftweb ^ -DarchetypeArtifactId=lift-archetype-basic_2.9.1 ^ -DarchetypeVersion=2.5 ^ -DarchetypeRepository=https://oss.sonatype.org/content/repositories/releases ^ -DgroupId=lift.cookbook ^ -DartifactId=chap01-mvn ^ -Dversion=1.0
After running the previous command, Maven will start to download all the required libraries to create the project.
Once the download is complete, Maven will ask you to confirm some information about the project. Confirm them by typing
Yand pressing return.Change the following tags in the
pom.xmlfile:From:
<scala.version>2.9.1</scala.version>
To:
<scala.version>2.10</scala.version>
From:
<artifactId>lift-mapper_2.9.1</artifactId>
To:
<artifactId>lift-mapper_2.10</artifactId>
From:
<artifactId>lift-jquery-module_2.9.1</artifactId> <version>2.5-2.0</version>
To:
<artifactId>lift-jquery-module_2.5_2.10</artifactId> <version>2.4</version>
From:
<groupId>org.scala-tools</groupId> <artifactId>maven-scala-plugin</artifactId> <version>2.15.2</version>
To:
<groupId>net.alchim31.maven</groupId> <artifactId>scala-maven-plugin</artifactId> <version>3.1.5</version>
From:
<groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <version>6.1.26</version>
To:
<groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId>
When you have finished editing the
pom.xmlfile, open a cmd window, go to the folder containing thepom.xmlfile, and run the following command to update and compile the project:mvn compileOnce Maven finishes the compilation, you will be able to start the application by running the following command:
mvn jetty:runNow that you have the application up and running, you can access
http://localhost:8080in your favorite browser, and you should see a welcome page similar to the following:
When you create a project using the Lift archetype, you get a fully working application containing everything you need to build your own application. This means that Maven will create an application with its default directory structure, a pom.xml file, with everything needed by the sample application. It will also include the jetty plugin that will allow us to run the application by running the jetty:run command.
The application created by Maven is a sample application that contains Blueprint CSS and a Mapper model. One more thing to notice is that this archetype also includes plugins for IntelliJ IDEA and Scala IDE.
