Interface CopySpec

All Superinterfaces:

ContentFilterable, CopyProcessingSpec, CopySourceSpec, PatternFilterable

All Known Implementing Classes:

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:

 into('webroot')
 exclude('**/.svn/**')
 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.

closure - to implement line based filtering

Returns:

this

expand

CopySpec expand(Map<String,?> properties)

Expands property references in each file as it is copied. More specifically, each file is transformed using Groovy's SimpleTemplateEngine.

You can also include arbitrary Groovy code in the file, such as ${version ?: 'unknown'} or ${classpath*.name.join(' ')}

Specified by:

expand in interface ContentFilterable

Parameters:

properties - to implement line based filtering

Returns:

this

eachFile

CopySpec eachFile(Action<? super FileCopyDetails> action)

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(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.
