Problem when extracting a zip using Copy


(nm2501) #1

I’m using Gradle 1.4 on Windows 7. When I use this code:

task testCopy(type: Copy) {
    def src = /C:\path\to\my.zip/
    def dest = /d:\destination\dir/
    into "."
    from (zipTree(src)) {
        into dest
    }
}

I get the following stacktrace:

FAILURE: Build aborted because of an internal error.
  * What went wrong:

    BUILD FAILED

Although this script looked sensible to me, the error is not very helpful. I now know that I can fix the script as follows:

task testCopy(type: Copy) {
    def src = /C:\path\to\my.zip/
    def dest = /d:\destination\dir/
    into dest
    from zipTree(src)
}

Why couldn’t Gradle deal with the initial script? And if that’s not a solvable problem, could the error message be made more useful?

Thanks, Neil
