Change in copy method in 4.3.1

I’m trying to upgrade an old gradle build to use a more modern version of Gradle and have hit a problem with a change in the copy() method syntax that seemed to occur in 4.3.1.

I had a task that was necessary to copy the CDI beans.xml file into the compiled sources (and similar in test sources).

classes.doLast {
    copy {
        from('src/main/resources') { include 'META-INF/beans.xml' }
        into "$buildDir/classes/main/"

This now doesn’t work:

Task :cell-executor:classes FAILED
A problem was found with the configuration of task ‘:cell-executor:classes’. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.

  • Directory ‘/home/timbo/github/im/squonk/squonk/components/cell-executor/src/main/resources/META-INF/beans.xml’ specified for property ‘$1’ is not a directory.

So 2 questions really:

  1. what has changed in the copy method syntax?
  2. is this still the best way to handle this?
