Create a Gradle Java Web Application and run on Gradle Tomcat Plugin

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 {

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

repositories {

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}",

buildscript {

    repositories {

    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
package org.o7planning.hellogradlewebapp.bean;

public class Greeting {

    public String getHello()  {
        return "Hello Gradle Web Application";
<!DOCTYPE html>

<meta charset="UTF-8">

<title>Hello Gradle Web App</title>

<jsp:useBean id="greeting" class="org.o7planning.hellogradlewebapp.bean.Greeting"/>


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

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