API Documentation:Sync

Synchronizes the contents of a destination directory with some source directories and files.

This task is like the Copy task, except the destination directory will only contain the files copied. All files that exist in the destination directory will be deleted before copying files, unless a Sync.preserve(org.gradle.api.Action) is specified.

Examples: 


// Sync can be used like a Copy task
// See the Copy documentation for more examples
task syncDependencies(type: Sync) {
    from 'my/shared/dependencyDir'
    into 'build/deps/compile'
}

// You can preserve output that already exists in the
// destination directory. Files matching the preserve
// filter will not be deleted.
task sync(type: Sync) {
    from 'source'
    into 'dest'
    preserve {
        include 'extraDir/**'
        include 'dir1/**'
        exclude 'dir1/extra.txt'
    }
}

Properties

PropertyDescription
caseSensitive

Specifies whether case-sensitive pattern matching should be used.

destinationDir

The directory to copy files into.

dirPermissions

It is dependent on the copy action implementation whether these permissions will actually be applied. For details see ConfigurableFilePermissions.

duplicatesStrategy

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

excludes

The set of exclude patterns.

filePermissions

Property for querying and configuring file access permissions. If the property has no value set, that means that existing permissions are preserved. It is dependent on the copy action implementation whether these permissions will actually be applied. For details see ConfigurableFilePermissions.

includeEmptyDirs

Tells if empty target directories will be included in the copy.

includes

The set of include patterns.

preserve

The filter that defines which files to preserve in the destination directory.

source

The source files for this task.

Methods

MethodDescription
eachFile(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.

eachFile(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.

exclude(excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a FileTreeElement as its parameter. The closure should return true or false. Example:

exclude(excludes)

Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

exclude(excludes)

Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

exclude(excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

expand(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(' ')}

expand(properties, 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.

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.

AbstractCopyTask exclude(Closure excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a FileTreeElement as its parameter. The closure should return true or false. Example: 

copySpec {
  from 'source'
  into 'destination'
  //an example of excluding files from certain configuration:
  exclude { it.file in configurations.someConf.files }
}

If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

AbstractCopyTask exclude(Iterable<String> excludes)

AbstractCopyTask exclude(Spec<FileTreeElement> excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

AbstractCopyTask expand(Map<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(java.util.Map, org.gradle.api.Action) should be used to disable this behavior.

AbstractCopyTask expand(Map<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
}

AbstractCopyTask filesMatching(Iterable<String> patterns, Action<? super FileCopyDetails> action)
