Ant 模式匹配 - * 与 ** - 网页学习体会

问题描述：

我们正在使用 TeamCity 生成我们不想清理的 *.nupkg 工件.TeamCity 提供了一个字段，您可以在其中指定一个 ANT 样式的模式来指示您希望或不想清除哪些文件.让我们假设我们有以下不想被清理的文件:

We are using TeamCity to produce *.nupkg artifacts which we don't want to be cleaned up. TeamCity provides a field where you can specify an ANT-style pattern for indicating which files you do or don't want to be cleaned up. Let's assume for a second that we have the following files which we do not want to be cleaned up:

/a.nupkg
/dir1/b.nupkg
/dir1/dir2/c.nupkg

*.nupkg 模式是否匹配根目录和所有子目录中的 .nupkg 文件，或者确实需要使用 **.*nupkg 遍历所有目录?

Does the *.nupkg pattern match .nupkg files both in the root directory AND all child directories or do need to use **.*nupkg to traverse all directories?

我阅读了以下文档，但这对我来说仍然不明确:http://ant.apache.org/manual/dirtasks.html#patterns

I read the following documentation but this is still ambiguous to me: http://ant.apache.org/manual/dirtasks.html#patterns

如果有一个 Ant-Pattern 测试器(类似于 http://regexpal.com/)太棒了.

If there is an Ant-Pattern tester (similar to http://regexpal.com/) that would be amazing.

答

匹配所有目录中的所有文件(从基目录和更深的目录)

To match all files, in all directories (from the base directory and deeper)

**/*.nupkg

会匹配

sample.nupkg
sample-2.nupkg
tmp/sample.nupkg
tmp/other.nupkg
other/new/sample.nupkg

** 将匹配任何目录(多个目录深度).

** will match any directory (multiple directories deep).

*.nupkg 将匹配任何带有 nupkg 扩展名的文件.或者只是 * 将匹配任何文件或任何目录(但只有一个目录深度).

*.nupkg will match any file with the nupkg extension. Or just * will match any file or any directory (but just a single directory deep).

PS:没有 Ant Pattern Tester.
