      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`

    - #### expand

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

    - #### expand

          public AbstractCopyTask 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`
      Specified by:

      Parameters:
        `properties` - reference-to-value map for substitution
        `action` - action to perform additional configuration of the underlying template engine
      Returns:
        this
