从Gradle构建脚本中提取常用方法 [英] Extract common methods from Gradle build script

问题描述

我有一个Gradle构建脚本（ build.gradle ），其中我创建了一些任务。这些任务主要由方法调用组成。被调用的方法也在构建脚本中。

现在，情况如下：

我创建了大量的构建脚本，其中包含不同的任务，但是使用原始脚本中的相同方法。因此，我想以某种方式提取这些常用方法，因此我可以轻松地重复使用它们，而不是将其复制到我创建的每个新脚本中。

如果Gradle是PHP，类似以下内容将是理想的：

  //脚本内容
 ... 
 require（common-methods.gradle）; 
 ... 
 //更多脚本内容
  

但当然，是不可能的。或者是它？

无论如何，我怎么能达到这个结果？什么是最好的方法来做到这一点？我已经通读了Gradle文档，但似乎无法确定哪种方法最简单，最适合这种方法。

预先感谢！ / p>

更新：

我已经设法在另一个文件中提取方法

（使用 apply from：'common-methods.gradle' ），

所以结构如下：

 父/ 
 /build.gradle //原始构建脚本
 /common-methods.gradle //提取的方法
 /gradle.properties //构建脚本使用的属性
  

从 build.gradle 执行任务后，我碰到了成为一个新问题：显然，当它们在 common-methods.gradle 中时，方法不会被识别。

<如何解决这个问题？

共享方法是不可能的，但你可以共享包含闭包的额外属性，归结为相同的东西。例如，在 common-methods.gradle 中声明 ext.foo = {...} ，使用 apply from：来应用脚本，然后用 foo（）调用闭包。

I have a Gradle build script (build.gradle), in which I created some tasks. These tasks consist mostly of method calls. The called methods are also in the build script.

Now, here's the situation:

I am creating a fair amount of build scripts, which contain different tasks, but utilise the same methods from the original script. Thus, I would like to extract these "common methods" in some way, so I can easily re-use them instead of copying them for each new script I create.

If Gradle were PHP, something like the following would be ideal:

//script content
...
require("common-methods.gradle");
...
//more script content

But of course, that isn't possible. Or is it?

Anyway, how can I achieve this result? What is the best possible method to do this? I've read through the Gradle documentation already, but I can't seem to determine which method will be the easiest and best suited for this.

Thanks in advance!

UPDATE:

I've managed to extract the methods in another file

(using apply from: 'common-methods.gradle'),

so the structure is as follows:

parent/
      /build.gradle              // The original build script
      /common-methods.gradle     // The extracted methods
      /gradle.properties         // Properties used by the build script

After executing a task from build.gradle, I've bumped into a new problem: apparently, methods don't get recognized when they're in common-methods.gradle.

Any ideas on how to fix that?

解决方案

It isn't possible to share methods, but you can share extra properties containing a closure, which boils down to the same thing. For example, declare ext.foo = { ... } in common-methods.gradle, use apply from: to apply the script, and then call the closure with foo().
