Gradle笔记 五 Gradle 中的文件操作

//使用相对路径
File configFile = file('src/conf.xml')
configFile.createNewFile();
// 使用绝对路径
configFile = file('D:\\conf.xml')
println(configFile.createNewFile())
// 使用一个文件对象
configFile = new File('src/config.xml')
println(configFile.exists())

def collection = files('src/test1.txt',new File('src/test2.txt'),['src/test3.txt', 'src/test4.txt']) collection.forEach(){File it ->
it.createNewFile() //创建该文件
println it.name //输出文件名
}
Set set1 = collection.files // 把文件集合转换为java中的Set类型
Set set2 = collection as Set
List list = collection as List//  把文件集合转换为java中的List类型
for (item in list) { println item.name
}
def union = collection + files('src/test5.txt') // 添加或者删除一个集合
def minus = collection - files('src/test3.txt') union.forEach(){File it ->
println it.name
}

tree = fileTree('src/main').include('**/*.java')// 第一种方式:使用路径创建文件树对象，同时指定包含的文件
//第二种方式:通过闭包创建文件树:
tree = fileTree('src/main') {
include '**/*.java'
}
tree = fileTree(dir: 'src/main', include: '**/*.java') //第三种方式:通过路径和闭包创建文件树：具名参数给map传值tree = fileTree(dir: 'src/main', includes: ['**/*.java', '**/*.xml', '**/*.txt'], exclude: '**/*test*/**')
tree.each {File file -> // 遍历文件树的所有文件
println file println file.name
}

task copyTask(type: Copy) { 
    from 'src/main/resources'
    into 'build/config'
}

task copyTask(type: Copy) {
// 拷贝src/main/webapp目录下所有的文件
from 'src/main/webapp'
// 拷贝单独的一个文件
from 'src/staging/index.html'
// 从Zip压缩文件中拷贝内容
from zipTree('src/main/assets.zip')
// 拷贝到的目标目录
into 'build/explodedWar'
}

task copyTaskWithPatterns(type: Copy) { 
    from 'src/main/webapp'
   into 'build/explodedWar'
   include '**/*.html' 
   include '**/*.jsp'
   exclude { details -> details.file.name.endsWith('.html') }
}

task rename(type: Copy) { 
    from 'src/main/webapp' 
    into 'build/explodedWar'
// 使用一个闭包方式重命名文件
    rename { String fileName -> fileName.replace('-staging-', '')
    }
}

task copyMethod {
doLast {
 copy {
    from 'src/main/webapp' 
    into 'build/explodedWar' 
    include '**/*.html' 
    include '**/*.jsp'
}
}
}

copy {
//相对路径或者绝对路径
from file('src/main/resources/ddd.txt') //file也可以换成new File()
into this.buildDir.absolutePath
}

apply plugin: 'java' version=1.0
task myZip(type: Zip) { 
    from 'src/main'
    into 'build' //保存到build目录中
    baseName = 'myGame'
}
println myZip.archiveName

gradle -q myZip 
myGame-1.0.zip

// 使用zipTree
FileTree zip = zipTree('someFile.zip')
// 使用tarTree
FileTree tar = tarTree('someFile.tar')
