View more Tutorials:
- File/New/Other...


Enter the name of the project:
- HelloGradleWebApp



Project is created:

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.![]()
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.


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>
Open "Gradle Task" view.

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

![]()
Right-click on "build" and select "Run Gradle Tasks".

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