# Tar

API Documentation: | `Tar`

Assembles a TAR archive.

### Properties

Property | Description
`appendix` | The appendix part of the archive name, if any.
`archiveName` | The archive name. If the name has not been explicitly set, the pattern for the name is: `[baseName]-[appendix]-[version]-[classifier].[extension]`
`archivePath` | The path where the archive is constructed. The path is simply the `destinationDir` plus the `archiveName`.
`baseName` | The base name of the archive.
`caseSensitive` | Specifies whether case-sensitive pattern matching should be used.
`classifier` | The classifier part of the archive name, if any.
`compression` | The compression that is used for this archive.
`destinationDir` | The directory where the archive is generated into.
`dirMode` | The Unix permissions to use for the target directories. `null` means that existing permissions are preserved. It is dependent on the copy action implementation whether these permissions will actually be applied.
`excludes` | The set of exclude patterns.
`extension` | The extension part of the archive name.
`fileMode` | The Unix permissions to use for the target files. `null` means that existing permissions are preserved. It is dependent on the copy action implementation whether these permissions will actually be applied.
`includeEmptyDirs` | Tells if empty target directories will be included in the copy.
`includes` | The set of include patterns.
`source` | The source files for this task.
`version` | The version part of the archive name, if any.

### Methods

Method | Description
`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(' ')}`
`filter(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.
`filter(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, 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.
`from(sourcePath, c)` | Specifies the source files or directories for a copy and creates a child `CopySourceSpec`. The given source path is evaluated as for `Project.files()` .
`from(sourcePaths)` | Specifies source files or directories for a copy. The given paths are evaluated as for `Project.files()`.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. The given closure is passed a `FileTreeElement` as its parameter. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`into(destPath)` | Specifies the destination directory *inside* the archive for the files. The destination is evaluated as for `Project.file()`. Don't mix it up with `AbstractArchiveTask.getDestinationDir()` which specifies the output directory for the archive.
`into(destPath, configureClosure)` | Creates and configures a child `CopySpec` with a destination directory *inside* the archive for the files. The destination is evaluated as for `Project.file()`. Don't mix it up with `AbstractArchiveTask.getDestinationDir()` which specifies the output directory for the archive.
`rename(closure)` | Renames a source file to a different relative location under the target directory. The closure will be called with a single parameter, the name of the file. The closure should return a String object with a new target name. The closure may return null, in which case the original name will be used.
`rename(sourceRegEx, replaceWith)` | Renames files based on a regular expression. Uses java.util.regex type of regular expressions. Note that the replace string should use the '$1' syntax to refer to capture groups in the source regular expression. Files that do not match the source regular expression will be copied with the original name.
