## Interface CopySpec

  All Known Subinterfaces:

      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
       }

          CopySpec filter​(java.util.Map<java.lang.String,​?> properties,
                          java.lang.Class<? extends java.io.FilterReader> filterType)

      Adds a content filter to be used during the copy. Multiple calls to filter, add additional filters to the filter chain. Each filter should implement `java.io.FilterReader`. Include `org.apache.tools.ant.filters.*` for access to all the standard Ant filters.

      Filter properties may be specified using groovy map syntax.

      Examples:

              filter(HeadFilter, lines:25, skip:2)
              filter(ReplaceTokens, tokens:[copyright:'2009', version:'2.3.1'])

      Specified by:
        `filter` in interface `ContentFilterable`
      Parameters:
        `properties` - map of filter properties
        `filterType` - Class of filter to add
      Returns:
        this

          CopySpec filter​(java.lang.Class<? extends java.io.FilterReader> filterType)

      Adds a content filter to be used during the copy. Multiple calls to filter, add additional filters to the filter chain. Each filter should implement `java.io.FilterReader`. Include `org.apache.tools.ant.filters.*` for access to all the standard Ant filters.

      Examples:

              filter(StripJavaComments)
              filter(com.mycompany.project.CustomFilter)

      Specified by:
        `filter` in interface `ContentFilterable`
      Parameters:
        `filterType` - Class of filter to add
      Returns:
        this

    - #### filter

          CopySpec filter​(Closure closure)

      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
      Returns:
        this

    - #### filter

          CopySpec filter​(Transformer<java.lang.String,​java.lang.String> transformer)

      Adds a content filter based on the provided transformer. 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:
        `transformer` - to implement line based filtering
      Returns:
        this

    - #### expand

          CopySpec expand​(java.util.Map<java.lang.String,​?> properties)

      Expands property references in each file as it is copied. More specifically, each file is transformed using Groovy's `SimpleTemplateEngine`. This means you can use simple property references, such as `$property` or `${property}` in the file. You can also include arbitrary Groovy code in the file, such as `${version ?: 'unknown'}` or `${classpath*.name.join(' ')}`

      Note that all escape sequences (`\n`, `\t`, `\\`, etc) are converted to the symbols they represent, so, for example, `\n` becomes newline. If this is undesirable then `ContentFilterable.expand(Map, Action)` should be used to disable this behavior.

      Specified by:
        `expand` in interface `ContentFilterable`
      Parameters:
        `properties` - reference-to-value map for substitution
      Returns:
        this

    - #### expand

          CopySpec expand​(java.util.Map<java.lang.String,​?> properties,
                          Action<? super ExpandDetails> action)

      Expands property references in each file as it is copied. More specifically, each file is transformed using Groovy's `SimpleTemplateEngine`. This means you can use simple property references, such as `$property` or `${property}` in the file. You can also include arbitrary Groovy code in the file, such as `${version ?: 'unknown'}` or `${classpath*.name.join(' ')}`. The template engine can be configured with the provided action.

      Note that by default all escape sequences (`\n`, `\t`, `\\`, etc) are converted to the symbols they represent, so, for example, `\n` becomes newline. This behavior is controlled by `ExpandDetails.getEscapeBackslash()` property. It should be set to `true` to disable escape sequences conversion:

            expand(one: '1', two: 2) {
                escapeBackslash = true
            }

      Specified by:
        `expand` in interface `ContentFilterable`
      Parameters:
        `properties` - reference-to-value map for substitution
        `action` - action to perform additional configuration of the underlying template engine
      Returns:
        this

    - #### eachFile

          CopySpec eachFile​(Action<? super FileCopyDetails> action)

      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.
      Returns:
        this

    - #### eachFile

          CopySpec eachFile​(@DelegatesTo(FileCopyDetails.class)
                            Closure closure)

      Adds an action to be applied to each file as it about to be copied into its destination. The given closure is called with a `FileCopyDetails` as its parameter. Actions are executed in the order added, and are inherited from the parent spec.
      Specified by:
        `eachFile` in interface `CopyProcessingSpec`
      Parameters:
        `closure` - The action to execute.
      Returns:
        this

    - #### getFilteringCharset

          java.lang.String getFilteringCharset()

      Gets the charset used to read and write files when filtering. By default, the JVM default charset is used.
      Returns:
        the charset used to read and write files when filtering
      Since:
        2.14

    - #### setFilteringCharset

          void setFilteringCharset​(java.lang.String charset)

      Specifies the charset used to read and write files when filtering.
      Parameters:
        `charset` - the name of the charset to use when filtering files
      Since:
        2.14
