使用SVN将一些模板文本包含到源文件中的好方法？ [英] A good solution to include some template text into a source file using SVN?

问题描述

我在SVN存储库中有一个Java项目，带有一堆.java文件，每个文件在文件顶部都有一个许可协议花箱（我的客户已经许可了源以及正在运行产品）。

I have a Java project in a SVN repository, with a bunch of .java files, each of those files has a licence agreement flower box at the top of the file (I have customers which have licenced the source as well as running the product).

是否有一种很好的方法可以在一个地方修改/维护许可文本，而不是必须手动更新所有源文件？

Is there a good way to be able to modify / maintain the licence text in one place rather than having to update all the source files manually if it changes?

看一些类似（但不完全相同）的问题，似乎SVN没有开箱即用的这种功能 - 其他哪种方法最适合？

Looking at some similar (but not identical) questions it seems like SVN does not have this functionality out of the box - what other approaches would be most suitable?

编辑：理想情况下，解决方案的行为类似于SVN关键字（Id，Author等），而不是构建时解决方案。客户也可以访问SVN存储库，因此如果许可证文本存在于文件的SVN版本中，那将是理想的。我知道SVN有提交触发器 - 实现它的简单方法是什么？

Ideally the solution would act like the SVN keywords (Id, Author etc.) rather than being a build-time solution. The customer has access to the SVN repository too, so it would be ideal if the licence text was present in the SVN version of the file. I know SVN has commit triggers - what's a simple way to implement that?

编辑2：看看SVN钩子它看起来不像我想要的做是可能的。我想在文本更改时可以运行的构建过程是正确的 - 因为它不会经常更改。

Edit 2: Looking at the SVN hooks it doesn't look like what I'd like to do is possible. I guess build process that can be run when the text changes is ok - since it won't change too often.

推荐答案

修改需要包含许可证文本以包含某些令牌的源文件，然后将许可证文本移动到保存在subversion中的单个文件中。最后，作为构建过程的一部分，添加一个步骤，用于替换令牌的许可证文本。在我的工作中，我使用sed和make的组合在这些方面做了一些事情。然后，您可以在将源分发给客户之前执行此单步。

Modify the source files that need to contain the text of the license to contain some token instead, and then move the license text to a single file that's kept in subversion. Finally, as part of your build process, add a step that substitutes the text of the license for the token. At my job, I do something along these lines using a combination of sed and make. You could then execute this single step before distributing the source to your customers.
