[GRADLE-1566] Copy filtering/expansion needs to be more selective on what content is filtered to avoid corrupting binary files Created: 22/May/11  Updated: 18/Nov/13  Resolved: 18/Nov/13

 Description   

I have found the filtering and expansion of the war task (and subsequently all copy tasks) to be problematic due to every file being attempted to be read as a text file with a certain encoding. This means that when binary files are read, they are written back out incorrectly.

I have had related problems with the expand() tool and binary files that contain characters that it can't parse.

A potential solution would be to all of the filter/expand operation to operate on a subset of what is being copied.

Last paragraph should be: “A potential solution would be to have the filter/expand operation(s) operate on a subset of what is being copied.

The work-around I'm using for my pain-point is:

processResources {
inputs.properties( version: version.toString() )
from(sourceSets.main.resources.srcDirs)

{ include '**/*.properties' filter(org.apache.tools.ant.filters.ReplaceTokens, tokens: [VERSION: version.toString()]) }

from(sourceSets.main.resources.srcDirs)

{ exclude '**/*.properties' }

}

Note that I'm only seeing corruption of binary files in Linux. None on OSX.

We just ran across this issue and was surprised to find it was reported in 1.0-milestone-3 and still exists 2 years later in 1.6. I see that there is a workaround, but are there any plans on fixing the bug? If not, this issue should just be closed.

+1 filtering should not corrupt binary files

Comment by Adam Murdoch [ 11/Nov/13 ]

Can we close this now that we have filesMatching() and filesNotMatching()?

Comment by MikeN [ 17/Nov/13 ]

I think so, the following seems to work fine:

processResources {
    inputs.property('version', version)

    filesMatching("**/version.properties") {
        expand version: version
    }
}
