This is a simple gradle task for changing line endings in files.

How to use

Copy the source code of this task to your_project_dir/buildSrc/src/main/groovy/ChangeLineEndings.groovy

Usage example:

task fixLineEndings(type: ChangeLineEndings) {
	changeTo LF
	forFile "$buildDir/artifacts/setup.sh"
	forFile "$buildDir/artifacts/run.sh"
}

changeTo accepts one parameter, which has to be either CRLF, CR or LF.

Restrictions

For now it's not possible to use wildcards in file paths supplied to forFile.
