默认情况下，Liferay是用的Ant来完成编译，打包部署的，你可以轻易的在SDK中找到相应的Ant脚本，当然了， 我们也可以用Maven来完成这个目标：

首先，我们必须添加liferay相关的maven原型(archetype),在Windows->Preference->Maven->Archetype中：

这样我们的Maven创建向导中就有了 Liferay相关的原型：

 

我们现在用Maven向导来创建

我们选择liferay-portlet-archetype:

 

创建完了之后的portlet应该有如下的目录结构：

 

我们编辑pom.xml ,添加2个属性，一个是liferay.version,一个是liferay.auto.deploy.dir,

最终的pom.xml是这样的：

1. <?xml version="1.0"?> 
2.  
3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

编辑我们的liferay应用，比如我们需要显示一些内容，所以更改view.jsp：

1. <%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %> 
2.  
3. <portlet:defineObjects /> 
4.  
5. This is the <b>charles-portlet</b>. 
6. This is the portlet created by charles using maven. 

 

我们创建一个Maven配置来编译，打包，部署之，如下图：

 

最终控制台正式编译，打包，部署：

1. ... 
2.  
3. [DEBUG] Configuring mojo com.liferay.maven.plugins:liferay-maven-plugin:6.1.0:deploy from plugin realm ClassRealm[plugin>com.liferay.maven.plugins:liferay-maven-plugin:6.1.0, parent: sun.misc.Launcher$AppClassLoader@11b86e7]

看出被打包的portlet叫 charles-portlet-0.0.1-SNAPSHOT.war

并且部署到了LIFERAY_HOME下deploy目录中

 

我们启动Liferay,和预期一样
