使用Gradle快速构建Java项目

如果仅用Gradle创建Java项目的话，还需要自己去创建Java Source包，建Web项目就更麻烦了。在网上找到了插件gradle-templates，用它建项目就比较方便了。

首先，用git clone插件代码，或者在项目右侧点击“Download ZIP”下载解压。

进入gradle-templates目录，执行(前提要装好gradle):

gradle build

编译完后，在你要创建工程的目录下新建build.gradle和gradle.properties两个文件，两个文件的内容分别如下：

build.gradle：
          apply from: 'file:///D:/gradle-templates/installation/apply-local.groovy'

gradle.properties：
          gradle.templates.dir=D:/gradle-templates
          gradle.templates.ver=1.4

上面两个文件的路径是gradle-templates目录。到此基本就配好了。可以执行gradle tasks，可以看到如下结果：

Template tasks
--------------
createGradlePlugin - Creates a new Gradle Plugin project in a new directory named after your project.
createGroovyClass - Creates a new Groovy class in the current project.
createGroovyProject - Creates a new Gradle Groovy project in a new directory named after your project.
createJavaClass - Creates a new Java class in the current project.
createJavaProject - Creates a new Gradle Java project in a new directory named after your project.
createScalaClass - Creates a new Scala class in the current project.
createScalaObject - Creates a new Scala object in the current project.
createScalaProject - Creates a new Gradle Scala project in a new directory named after your project.
createWebappProject - Creates a new Gradle Webapp project in a new directory named after your project.
initGradlePlugin - Initializes a new Gradle Plugin project in the current directory.
initGroovyProject - Initializes a new Gradle Groovy project in the current directory.
initJavaProject - Initializes a new Gradle Java project in the current directory.
initScalaProject - Initializes a new Gradle Scala project in the current directory.
initWebappProject - Initializes a new Gradle Webapp project in the current directory.

现在就可以构建项目了，执行：

gradle createWebappProject

输入相应的Project Name，Use Jetty Plugin? (Y|n)，Group: [gradlewebapp] ， Version: [1.0]后，Java Web项目就创建成功了。当然，这还不能知道导入到eclipse下。进入到刚才创建的目录下，修改build.gradle文件，使其包含如下内容：

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

执行“gradle eclipse”和“gradle eclipseWtp”后就可以将项目导入到Eclipse了。不过导入的项目不是Gradle Project，可以右击项目-->Configure-->Convert to Gradle Project后，项目就可以在Eclipse下用Gradle编译打包了。
