最近项目中使用了Gradle来进行构建，项目选型用的是springboot，打包后是jar方式运行。但是在以前，公司使用的webproject，在不改变tomcat运行环境的情况下，如何做到gradle进行编译和测试呢？下面将用一个实例讲解如何eclipse的web project和gradle进行集成。
新建Dynamic Web Project，命名为GradleWeb。记得勾选生成web.xml复选框。
GIT:http://git.oschina.net/renchhao/gradle-test
在新建的项目下web项目根目录新建build.gradle文件，同时编写构建脚本。如下：
import org.gradle.plugins.ide.eclipse.model.Facet
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse-wtp'
webAppDirName = 'WebContent'
sourceSets.main.java.srcDir 'src'
version = '1.0'
sourceCompatibility = 1.8
[compileJava]*.options*.encoding = 'UTF-8'
repositories {
maven { url 'http://maven.aliyun.com/nexus/content/groups/public'}
mavenLocal()
mavenCentral()
}
ext {
warName = 'gradle_test'
springVersion = '4.2.3.RELEASE'
hibernateVersion = '5.0.5.Final'
hibernateSearchVersion = '5.5.1.Final'
freemarkerVersion = '2.3.23'
httpclientVersion = '4.5'
jacksonVersion = '2.6.1'
}
war{
baseName ="${warName}"
from("$projectDir/src/") {
include "**/*.xml"
include "**/*.properties"
into('WEB-INF/classes')
}
}
dependencies {
compile (
"org.freemarker:freemarker:${freemarkerVersion}",
'commons-logging:commons-logging:1.2',
'commons-io:commons-io:2.4',
'commons-fileupload:commons-fileupload:1.3.1',
'commons-codec:commons-codec:1.10',
'org.apache.commons:commons-collections4:4.0',
'org.apache.commons:commons-lang3:3.4',
"org.springframework:spring-context-support:${springVersion}",

'org.quartz-scheduler:quartz:2.2.1',
'cglib:cglib-nodep:3.1',
'dom4j:dom4j:1.6.1'
)
compile('javax.servlet:javax.servlet-api:3.1.0')
}
eclipse {
wtp {
facet {
facet name: 'jst.web', type: Facet.FacetType.fixed
facet name: 'wst.jsdt.web', type: Facet.FacetType.fixed
facet name: 'jst.java', type: Facet.FacetType.fixed
facet name: 'jst.java', version: '1.8'
facet name: 'jst.web', version: '3.1'
facet name: 'wst.jsdt.web', version: '1.0'
}
}
}
task warApp(dependsOn: war){
doLast{
def tempWarDirOut = new File("${buildDir}/tmp/warApplication")
tempWarDirOut.mkdirs()
ant.unwar(src: "${buildDir}/libs/${warName}-${version}.war",
dest: "${buildDir}/tmp/warApplication")
}
}
在构建脚本中，主要做了几件事，引用war插件，引用eclipse-wtp插件，用于识别eclipse项目和war包的打包。
repositories中指定了阿里云的maven仓库，国内比较快。ext中定义了几个变量，包括war包名称和依赖项的版本号。
其中的warApp这个自定义task是用于把war进行解压的操作，有些时候，可能使用war中的文件，所以进行一个war解压，以便后续的操作。
- 修改web.xml

为了做一个完成的mvc项目，我们继续增加mvc配置和代码。在WebContent/WEB-INF下新增app-servlet.xml

在eclipse中可以直接run on server，如果需要打包或者抽取文件，则执行gradle build/gradle warApp
