[GRADLE-2255] CopySpec.eachFile() not receiving empty directories from zipTree Created: 26/Apr/12  Updated: 10/Feb/17  Resolved: 10/Feb/17

Extracting a Zip archive that includes empty directories fails to send empty directories to CopySpec.eachFile(). For example:

file.zip contains:


copy {
from zipTree("file.zip")

{ it.setPath(it.getPath().replaceFirst("^zipRootPath", "destRootPath")) }

into "targetDir"

The above inputs will result in this file/directory structure in targetDir:


because "zipRootPath/emptyDir/" is never sent to the eachFile closure, above.

Current workaround:


{ from zipTree("file.zip") into "targetDir" }


The problem with the workaround is that multiple calls to copy

{ from zipTree() }

on a large ZIP file result in long ZIP extraction times (e.g. to extract different pieces of the ZIP file at different times, or to work around other Gradle ZIP extraction bugs).

Possible suggested solutions:

1) Modify the code that calls the eachFile closure to include directories
2) Add a call to a closure (eachEntry?) which receives all files and directories
3) Add a call to a closure that only receives directories

eachFile() does not support directories at the moment and it is indeed a missing capability. I have a feeling we already have few issues that directly/indirectly depend on that.

Thanks for reporting!
