CopySpec (Gradle API 2.14.1)

org.gradle.api.file

## Interface CopySpec

- All Superinterfaces:
    ContentFilterable, CopyProcessingSpec, CopySourceSpec, PatternFilterable
  All Known Implementing Classes:
    AbstractArchiveTask, AbstractCopyTask, Copy, Jar, ProcessResources, Sync, Tar, Zip

      public interface CopySpec
      extends CopySourceSpec, CopyProcessingSpec, PatternFilterable

  A set of specifications for copying files. This includes:
  - source directories (multiples allowed)
  - destination directory
  - ANT like include patterns
  - ANT like exclude patterns
  - File relocating rules
  - renaming rules
  - content filters
  CopySpecs may be nested by passing a closure to one of the from methods. The closure creates a child CopySpec and delegates methods in the closure to the child. Child CopySpecs inherit any values specified in the parent. This allows constructs like:

       def myCopySpec = project.copySpec {
         into('webroot')
         exclude('**/.data/**')
         from('src/main/webapp') {
           include '**/*.jsp'
         }
         from('src/main/js') {
           include '**/*.js'
         }
       }

  In this example, the `into` and `exclude` specifications at the root level are inherited by the two child CopySpecs. Copy specs can be reused in other copy specs via `with(CopySpec...)` method. This enables reuse of the copy spec instances.

       def contentSpec = copySpec {
         from("content") {
           include "**/*.txt"
         }
       }

       task copy(type: Copy) {
         into "$buildDir/copy"
         with contentSpec
       }

      Returns the strategy to use when trying to copy more than one file to the same destination.

      The value can be set with a case insensitive string of the enum value (e.g. `'exclude'` for `DuplicatesStrategy.EXCLUDE`).

      Filter properties may be specified using groovy map syntax.

      Examples:

              filter(HeadFilter, lines:25, skip:2)

      Adds a content filter based on the provided closure. The Closure will be called with each line (stripped of line endings) and should return a String to replace the line or `null` to remove the line. If every line is removed, the result will be an empty file, not an absent one.
      Specified by:
        `filter` in interface `ContentFilterable`
      Parameters:
        `closure` - to implement line based filtering

      Specified by:
        `expand` in interface `ContentFilterable`
      Parameters:
        `properties` - to implement line based filtering

      Adds an action to be applied to each file as it is about to be copied into its destination. The action can change the destination path of the file, filter the contents of the file, or exclude the file from the result entirely. Actions are executed in the order added, and are inherited from the parent spec.
      Specified by:
        `eachFile` in interface `CopyProcessingSpec`
      Parameters:
        `action` - The action to execute.
