如何使用Eclipse将Gradle Web应用程序部署到tomcat

Question

I'm trying to understand the way gradle work with eclipse.

I can't figure out how to add my webb app to the tomcat server. It does not appear.

Some mention cargo plugin but i can't get it to work either.

Here are my plugins :

apply plugin: 'base'
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse'
apply plugin: 'eclipse-wtp'

Answer 1

May be I am late in joining the party but it may help some one else.

Actually there is no need for `apply plugin: 'eclipse-wtp'.

A cargo plugin is useful for deploying application using gradle.

Some incites from cargo documentation:

The plugin provides deployment capabilities for web applications to local and remote containers in any given Gradle build by leveraging the Cargo Ant tasks. The plugin supports WAR and EAR artifacts.

Starting with technical parts:

Step 1: You need to add the below two imports in your gradle scripts. It will enable the cargo plugin for your build.

apply plugin: 'com.bmuschko.cargo'
apply plugin: 'com.bmuschko.tomcat'

Step 2: Specify the dependencies in your buildscripts

buildscript {

    dependencies {
         classpath 'com.bmuschko:gradle-cargo-plugin:2.2.3'
         classpath 'com.bmuschko:gradle-tomcat-plugin:2.4.1'

    }
}

Step 3: Add the dependencies for the tomcat and cargo

dependencies {
    def tomcatVersion = '7.0.47'
    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}"

    def cargoVersion = '1.4.5'
    cargo ("org.codehaus.cargo:cargo-core-uberjar:$cargoVersion",
          "org.codehaus.cargo:cargo-ant:$cargoVersion")
}

Step 4: Download the tomcat zip file and extract it in some folder in your local. Add the following code to your build.gradle

cargo {
    containerId = 'tomcat7x'
    port = 9090

    deployable {

        file = new File('C:/<path-to-your-war-file>/gradleTutorial.war')
        context = 'gradleTutorial'
    }

    local {
        homeDir = file('C:/<path-to-the-extracted-tomcat-folder>/tomcat-7.0.47')
        outputFile = file('build/output.log')
        timeout = 60000

        containerProperties {
            property 'cargo.tomcat.ajp.port', 9099
        }
    }   
}

Step 4: configure your tomcat as follows:

tomcat {
    httpPort = 9090
    httpsPort = 9091
    enableSSL = true
    contextPath = 'gradleTutorial'

}

Thats all. Once these steps are done. You must need to install gradle plugin in your eclipse from market place and you can configure as below screenshot
