1- Create Gradle Project

File/New/Other...

Enter the name of the project:

HelloGradleWebApp

Project is created:

2- Configuring Gradle

This is the default content of build.gradle file created by Eclipse, and remove all the comments:

build.gradle (ORIGIN CONTENT)

apply plugin: 'java'

repositories {
   jcenter()
}

dependencies {

   compile 'org.slf4j:slf4j-api:1.7.21'

   testCompile 'junit:junit:4.12'
 
}

You need to add the configuration for your application to become "WEB Application". And can be run directly on Eclipse + Tomcat Plugin.

See full code:

build.gradle

apply plugin: 'java'
apply plugin: 'war' 
apply plugin: 'com.bmuschko.tomcat'

repositories {
    jcenter()
}

dependencies {   
 
    testCompile 'junit:junit:4.12' 
  
    providedCompile "javax.servlet:javax.servlet-api:3.1.0"      
    
}


dependencies {
    def tomcatVersion = '7.0.59'
   
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
           "org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}",
           "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"
}


buildscript {

    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.bmuschko:gradle-tomcat-plugin:2.2.2'
    }
}

Note that each time there is a change in build.gradle you need to update the project, using the tool of Gradle.

3- Edit application structure

In "src/main" folder, you need to create 2 sub folders are "resources" and "webapp".

src/main/java: This folder has java sources.
src/main/resources: This folder can hold property files and other resources
src/main/webapp: This folder holds jsp and other web application content.

4- Code Project

Greeting.java

package org.o7planning.hellogradlewebapp.bean;

public class Greeting {

   
    public String getHello()  {
        return "Hello Gradle Web Application";
    }
   
}

hello.jsp

<!DOCTYPE html>
<html>
<head>

<meta charset="UTF-8">

<title>Hello Gradle Web App</title>
</head>
<body>

<jsp:useBean id="greeting" class="org.o7planning.hellogradlewebapp.bean.Greeting"/>
 
<h3>${greeting.hello}</h3>
 


</body>
</html>

5- Gradle Build

Open "Gradle Task" view.

Note: If you do not see "Gradle Task", you can open it by:

Window/Show View/Other...

Right-click on "build" and select "Run Gradle Tasks".

Check Gradle Executions tab, you should see a list of tasks executed.

6- Configure to run application

Enter:

Name: Run HelloGradleWebApp
Gradle Tasks: tomcatRun
Working Directory: ${workspace_loc:/HelloGradleWebApp}

Run URL:

http://localhost:8080/HelloGradleWebApp/hello.jsp

Note: You can also create other tasks with Gradle Tomcat Plugin:

Task Name	Depends On	Type	Description
tomcatRun	-	TomcatRun	Starts a Tomcat instance and deploys the exploded web application to it.
tomcatRunWar	-	TomcatRunWar	Starts a Tomcat instance and deploys the WAR to it.
tomcatStop	-	TomcatStop	Stops the Tomcat instance.
tomcatJasper	-	TomcatJasper	Runs the JSP compiler and turns JSP pages into Java source using Jasper.
