如何使用gradle构建工具打包groovy脚本成jar文件

准备工作安装 gradle， groovy。

要使用gradle的groovy plugin 来打包groovy 脚本，项目结构。

目大弊念录 含义

src/main/java Java 代码

src/main/resources Java需要的资源文件

src/main/groovy Groovy代码，也可以包含Java代码

src/test/javaJava 测试代码

src/test/resources测试需要的资源文件

src/test/groovyGroovy测试需要的资源文件

src/滚困sourceSet/java Java代码源

src/sourceSet/resources 资源文件源

src/sourceSet/groovy Groovy代码源

我们只需要编译打包groovy脚本 所以只需要创建 src/main/groovy目录结构。例子：卜旁

gradle_groovy_archive项目 结构是：

gradle_groovy_archive

创建helloWorld.groovy脚本，代码如下：

package hello

println 'Gradle compile groovy'

创建Gradle构建文件：

apply plugin: 'groovy'

apply plugin: 'maven'

group = 'com.hello'

archiveBaseName = 'hello'

version = '0.1-SNAPSHOT'

defaultTasks 'clean', 'jar'

configurations {

deployerJars

}

repositories {

mavenCentral()

}

dependencies {

//使用本地groovy环境

groovy localGroovy()

//groovy group: 'org.codehaus.groovy', name: 'groovy', version: '1.8.6'

compile fileTree( dir: 'lib', include: ['*.jar'])

deployerJars 'org.apache.maven.wagon:wagon-webdav-jackrabbit:1.0-beta-7'

}

sourceSets {

main {

groovy {

srcDir 'src/main/groovy'

}

}

}

uploadArchives {

repositories.mavenDeployer {

uniqueVersion = false

configuration = configurations.deployerJars

repository(id : repositoryId, url : repositoryUrl) {

authentication (userName : 'deployment', password : 'deployment')

proxy()

}

}

}

创建构建文件属性文件：

//根据不同情况修改

repositoryId=ND

repositoryUrl=ND

systemProp.http.proxyHost=ND

systemProp.http.proxyPort=8080

systemProp.http.proxyUser=ND

systemProp.http.proxyPassword=ND

在命令行中 敲 gradle 运行，会自动运行 defaultTasks,clean 和 jar，会把 所有groovy下的脚本打成jar包。

xml内容

<emails>

<email id= ′>

<subject>hello world</subject>

<sender></sender>

<receivedDate>: : </receivedDate>

</email>

<email id= ′>

<subject>hello world demo </subject>

<清搏轿sender></sender>

<receivedDate>: : </receivedDate>

</email>

<email id= ′>

<subject>hello world demo </subject>

<sender></sender>

<receivedDate>: : </receivedDate>

</email>

</emails>

def emails = new XmlParser() parse( emails xml )

emails email each {

println ${it @id} ${it subject text()}
