Maybe I can use a FileTree which extends FileCollection, and then filter.

Is this a good place to ask really basic build.gradle in groovy questions?

Definitely 🙂 First recommendation of course is, to not use Groovy DSL, but Kotlin DSL. 😄 It is the default by now, you immediately get type-safe build scripts, you get actually helpful error messages if you mess up the syntax, and you get amazingly better IDE support when using a proper IDE like IntelliJ IDEA or Android Studio.

Probably, yeah, with something like

from(zipTree(fileTree(".").matching { include("project-lib-*.zip") }.singleFile))

But the question is, whether you should really do that. 😄 Besides that in most situations a

Sync

task is more appropriate than a

Copy

task. 🙂

Thanks Vampire. Very helpful.
