Interface CopySpec

  • All Superinterfaces:
    ContentFilterable, CopyProcessingSpec, CopySourceSpec, PatternFilterable
    All Known Subinterfaces:
    SyncSpec
    All Known Implementing Classes:
    AbstractArchiveTask, AbstractCopyTask, Copy, Ear, Jar, Jar, ProcessResources, Sync, Tar, War, 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
 }

        void setCaseSensitive​(boolean caseSensitive)
        Specifies whether case-sensitive pattern matching should be used for this CopySpec.
        Parameters:
        caseSensitive - true for case-sensitive matching.

      • 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<@Nullable 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:

        Parameters:
        transformer - to implement line based filtering

      • 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.
