Gradle拷贝任务中的**含义

Question

嗨，我不完全理解Gradle复制任务中**的洞概念。例如

task copyPoems(type: Copy) {
 from 'text-files'
 into 'build/poems'
 include '**/sh*.txt'
}

使用和不使用**的include有什么区别？

Answer 1

'**‘表示包含子目录

include '**/sh*.txt'  // include all sh*.txt files in 'text-files' and any subdirectory

include 'sh*.txt'  // include all sh*.txt files in only the one directory (eg, 'text-files')

顺便说一句，它的用法与ant工具的用法完全相同，因为API是相同的。
