如何扩展gradle的clean任务来删除文件？ [英] How do I extend gradle's clean task to delete a file?

问题描述

到目前为止，我已将以下内容添加到我的build.gradle中：

  apply plugin：'base'
清洁<< {
 delete'$ {rootDir} / api-library / auto-generated-classes /'
 println'$ {rootDir} / api-library / auto-generated-classes /'
} 
  

然而，不仅我的文件没有被删除，而且print语句显示 $ {rootDir} 未被转换为我的项目的根目录。为什么不行，我缺少什么概念？

解决方案

您只需要使用双引号。另外，如果您打算在执行期间执行删除操作，请删除<< 并使用 doFirst 。像这样：

  clean.doFirst {
 delete$ {rootDir} / api-library / auto-generated -class /
 println$ {rootDir} / api-library / auto-generated-classes /
} 
  

Gradle构建脚本使用Groovy DSL编写。在Groovy中，您需要使用双引号进行字符串插值（当您使用 $ {} 作为占位符时）。查看此处。

So far i've added the following to my build.gradle

apply plugin: 'base' 
clean << {
    delete '${rootDir}/api-library/auto-generated-classes/'
    println '${rootDir}/api-library/auto-generated-classes/'
}

However not only is my file not deleted, but the print statement shows that ${rootDir} is not being converted to the root directory of my project. Why won't this work, what concepts am I missing?

解决方案

You just need to use double quotes. Also, drop the << and use doFirst instead if you are planning to do the deletion during execution. Something like this:

clean.doFirst {
    delete "${rootDir}/api-library/auto-generated-classes/"
    println "${rootDir}/api-library/auto-generated-classes/"
}

Gradle build scripts are written in Groovy DSL. In Groovy you need to use double quotes for string interpolation (when you are using ${} as placeholders). Take a look at here.
