Copy to project directory fails on Windows


(Ben Jansen) #1

I think I have run into an issue with Copy tasks. If the task is configured to copy into the project directory, on Windows it dies with an IOException. I’ve tried with Gradle 1.6 and Windows 7 & 2008. I created a tiny build to exhibit this problem and put it at https://github.com/aogail/gradle-copy-failure

Running this task from the above build on Windows always fails with the IOException below:

task fail(type: Copy) {
    from 'foo/foo.txt'
    into '.'
}
org.gradle.api.UncheckedIOException: java.io.IOException: The process cannot access the file because another process has
 locked a portion of the file
