Server technology First day (Gradle configuration and Getting started)

Gradle Overview:

In Gradle, there are two basic concepts: projects and tasks

Gradle just provides a framework for building projects, and what really works is plugin

1.gradle configuration (MAC):

(1) Download Gradle from official website:

Address: http://gradle.org/gradle-download/

(2) Installation Gradle:

1) Place the Gradle package file under/applications/gradle-2.6

2) Open the console to set environment variables:

VI. bash_profile

Add path= $PATH:/applications/gradle-2.6/bin/, Save and exit (: Wq)

Then enter the following command on the console
SOURCE ~/.bash_profile

3) Successful Installation

2.gradle Small Try A:

(1) Build a project (to get Gradle to build in the root directory of this project)

(2) Create a directory structure

Mkdir-p Src/main/java/hello (Create a multilevel package with the console or you can create it directly in the user interface)

　　　　　　Project

└──SRC    └──main        └──java  └──hello　　　　　　　　

(3) Create two Java files in the Hello directory, respectively Helloworld.java and Greeter.java

1 //Helloworld.java-----Src/main/java/hello/helloworld.java2    　　  PackageHello;3   4   　　   Public classHelloWorld {5     　　   Public Static voidMain (string[] args) {6LocalTime currenttime =Newlocaltime ();7System.out.println ("The current local time is:" +currenttime);8 9Greeter Greeter =NewGreeter ();Ten System.out.println (Greeter.sayhello ()); One } A } -   -   the  　　  //Greeter.java-----Src/main/java/hello/greeter.java -   　　  PackageHello; -   -  　　   Public classGreeter { +     　　  PublicString SayHello () { -       　　 return"Hello world!"; + } A}

(4) Create a build.gradle root directory: (gradle build Script build.gradle specifies a project and its tasks)

1repositories {//Import Web site2 mavencentral ()3  　　 }4 5Apply plugin: ' java '//Apply ' Java ' plugin to enable it to be compiled (Gradle build)6 7Apply plugin: ' Application '//Apply ' application ' plugin to enable it to be run (Gradle run)8 9Mainclassname = ' Hello '. HelloWorld '//Setting the main classTen  Onedependencies {//Download the supplemental package from the Web ACompile "joda-time:joda-time:2.2"//format is name: Name: Version -  　　 } -         

(5) Now, you have a project, the can build with Gradle ^_^
