实现文件上传进度条的javaweb工程之gradle实战
项目目录结构如下：.
├─scripts
└─src
    ├─main
    │  ├─java
    │  │  └─com
    │  │      └─hongfei
    │  │          ├─entity
    │  │          ├─lister
    │  │          └─servlet
    │  ├─resources
    │  └─webapp
    │      ├─js
    │      ├─META-INF
    │      ├─upload
    │      └─WEB-INF
    └─test
        ├─java
        └─resources
build.gradle文件的内容如下：
运行时必须先执行create_dirs创建src，

apply plugin: "war"
apply plugin: "eclipse"
apply plugin: "jetty"
//清除eclipse输出
task cleanEclipseOutput(type: Delete) {
  delete eclipse.classpath.defaultOutputDir
}

//创建src
task create_dirs << {
   sourceSets*.java.srcDirs*.each { it.mkdirs() }
   sourceSets*.resources.srcDirs*.each { it.mkdirs() }
}

dependencies {
  compile "commons-io:commons-io:2.0.1"
  compile "commons-fileupload:commons-fileupload:1.2.2"
  providedCompile "javax.servlet:servlet-api:2.5"
}
//cleanEclipseOutput-task必须放在这句话的前面
jettyRun.dependsOn cleanEclipseOutput

repositories {
		maven {
			url "http://localhost:8081/nexus/content/groups/public/"
		}
		mavenCentral name:'codehaus', artifactUrls: ["http://repository.codehaus.org/"]
		mavenCentral name:'ibiblio', artifactUrls: ["http://mirrors.ibiblio.org/pub/mirrors/maven2/"]
		mavenCentral name:'apache', artifactUrls: ["http://people.apache.org/repo/m2-ibiblio-rsync-repository/"]
		mavenCentral name:'maven', artifactUrls: ["http://repo2.maven.org/maven2/"]
		mavenCentral name:'lds', artifactUrls: ["https://code.lds.org/nexus/content/repositories/thirdparty/"]
		mavenCentral name:'m2m', artifactUrls: ["http://repository.m2m.io:8081/nexus/content/groups/public/"]
}
jettyRun {
  httpPort = 9080
  contextPath = ''
  classpath = files(eclipse.classpath.defaultOutputDir) + classpath
  reload = 'manual'
}

运行时必须先执行create_dirs创建src；

在依赖（dependencies）中添加j2ee环境支持providedCompile "javax.servlet:servlet-api:2.5"

jettyRun.dependsOn cleanEclipseOutput，是在jetty运行时清空eclipse输出。

jettyRun {
  httpPort = 9080
  contextPath = ‘‘
  classpath = files(eclipse.classpath.defaultOutputDir) + classpath
  reload = ‘manual‘
  //scanIntervalSeconds = 1
}

设置9080为jetty端口

contextPath为路径

项目辅助bat脚本如下：

build-gradle.bat:

@echo off
cd ..
gradle create_dirs build eclipse 2>&1 1>log.txt  2>>log.txt  1>>con   2>>con & pause

@echo off
cd ..

gradle cleanEclipse clean 2>&1 1>log.txt  2>>log.txt  1>>con   2>>con & rmdir /s /q .gradle & pause

@echo off

cd ..
set GRADLE_OPTS=-Xmx512m -XX:MaxPermSize=512m -Xdebug -Xrunjdwp:transport=dt_socket,address=9000,server=y,suspend=n
set GRADLE_USER_HOME=%UserProfile%\.gradle-p2p-pro-app

gradle jettyRun 2>&1 1>log.txt  2>>log.txt  1>>con   2>>con & pause

start-gradle.bat（启动eclipse，必须设置setenv.bat）：

@echo off
call "%~dp0setenv"
cd ..
start "ECLIPSE" "%ECLIPSE_HOME%\eclipse.exe" -vm "%JAVA_HOME%\bin\javaw.exe"

set JAVA_HOME=E:\tools\jdk1.6
set GRADLE_HOME=E:\tools\gradle-1.9
set ECLIPSE_HOME=E:\tools\eclipse ee\eclipse
set PATH=%JAVA_HOME%\bin;%GRADLE_HOME%\bin;%PATH%
