grade task 批量替换packageName

task replacePackageName {

   FileTree tree = fileTree(dir:'src')

    tree.include'**/*.java'

    tree.include'**/*.xml'

    tree.each {File mfile ->

      fileReader(mfile.path,targetName)

}

//    fileReader("build.gradle", packageName)

}

def  fileReader(path, target_package) {

    def readerString ="";

    def hasReplace =false

    file(path).withReader('UTF-8') { reader ->

         reader.eachLine {

               if(it.find("com.lzl.test")) {

                        it = it.replace("com.lzl.test", target_package)

                         hasReplace =true

             }

                  readerString <<= it

                  readerString <<'\n'

}

if(hasReplace) {

           println(path +" has replace package.")

            file(path).withWriter('UTF-8') {

              within ->

               within.append(readerString)

     }

}

     return     readerString

}

}

使用方式：

先把包名所在文件夹名字改了，然后把task放到gradle中。执行task。批量替换修改后的包名
