[GRADLE-3198] The gradle copy task is not honouring the caseSensitive property. Created: 20/Nov/14  Updated: 10/Feb/17  Resolved: 10/Feb/17

I'm having a problem with the Copy task-type in gradle, namely that it doesn't copy all the files I want.
I'm copying a tree full of *.ddl files, but some are called *.DDL, and those don't get copied, even though I set caseSensitive = false in the copy task.

I created the following test build to show the problem:

task makefiles << {
mkdir 'fromtest'
file('fromtest/lower.foo').write('Test file lower case foo')
file('fromtest/upper.FOO').write('Test file upper case FOO')
file('fromtest/lower.foobar').write('Test file lower case bar')

task copyfoo (type: Copy, dependsOn: makefiles) {
into 'totest'
from 'fromtest'
include '*.foo'
caseSensitive = false

task show(dependsOn: copyfoo) << {

{ println it.name }


The code above only copies lower.foo, whereas I would expect it to also copy upper.FOO
What am I doing wrong ?

I have the same issue.
Has anybody an idea? Is this a known bug?

I have created a workaround for this bug (I assume this is a bug!).
Sorry if this looks a bit cluttered - I am a beginner in groovy


  • Workaround for broken caseSensitive property of the copy task.
  • Checks whether the file starts with given extension prefix and if
  • the given path segment is part of the files path.
  • Both checks are case insensitive.
  • @param fileTreeElement The FileTreeElement instance to check.
  • @param extPrefix The prefix of the file extension.
  • @param pathSegment Optional part of the file path.
  • Backward slashes are converted to forward slashes!
  • @return boolean
    def checkExtension(fileTreeElement, extPrefix, pathSegment='') {
    def path = fileTreeElement.getPath().toLowerCase().replace("
    ", "/")
    def lext = path.split('[.]')
    def ll = lext.length
    def ext = ''
    if (ll > 1) { ext = lext[ll - 1] }

    path.contains(pathSegment) && ext.startsWith(extPrefix)

use this in the copy task as follows:

task copyExcel(type: Copy, dependsOn: copyXmlGen) {
from srcDir
into defaultDir + '/common/gtnexus'
includeEmptyDirs false

{checkExtension(it, 'xl', 'com/foo/bar')}
