# SourceDirectorySet

API Documentation: | `SourceDirectorySet`

Known Subtypes: |
`GroovySourceDirectorySet`
`ScalaSourceDirectorySet`
`AntlrSourceDirectorySet`

A `SourceDirectorySet` represents a set of source files composed from a set of source directories, along with associated include and exclude patterns.

`SourceDirectorySet` extends `FileTree`. The contents of the file tree represent the source files of this set, arranged in a hierarchy. The file tree is live and reflects changes to the source directories and their contents.

You can create an instance of `SourceDirectorySet` using the `ObjectFactory.sourceDirectorySet(java.lang.String, java.lang.String)` method.

You can filter the files that are obtainable in this set using patterns via <UNHANDLED-LINK>#include(Spec)</UNHANDLED-LINK> and <UNHANDLED-LINK>#include(Spec)</UNHANDLED-LINK> (or any overload of these methods). The set of included source directories themselves are not filtered.

### Properties

Property | Description
`classesDirectory` | The directory property that is bound to the task that produces the output via `SourceDirectorySet.compiledBy(org.gradle.api.tasks.TaskProvider, java.util.function.Function)`. Use this as part of a classpath or input to another task to ensure that the output is created before it is used. Note: To define the path of the output folder use `SourceDirectorySet.getDestinationDirectory()`
`destinationDirectory` | Configure the directory to assemble the compiled classes into.
`filter` | The filter used to select the source from the source directories. These filter patterns are applied after the include and exclude patterns of this source directory set. Generally, the filter patterns are used to restrict the contents to certain types of files, eg `*.java`.
`srcDirs` | The source directories that make up this set.

### Methods

Method | Description
`compiledBy(taskProvider, mapping)` | Define the task responsible for processing the source.
`source(source)` | Adds the given source to this set.
`srcDir(srcPath)` | Adds the given source directory to this set. The given directory does not need to exist. Directories that do not exist are ignored.
`srcDirs(srcPaths)` | Adds the given source directories to this set. The given directories do not need to exist. Directories that do not exist are ignored.

### Property details

#### ``Provider`<`Directory`>` `classesDirectory`

The directory property that is bound to the task that produces the output via `SourceDirectorySet.compiledBy(org.gradle.api.tasks.TaskProvider, java.util.function.Function)`. Use this as part of a classpath or input to another task to ensure that the output is created before it is used. Note: To define the path of the output folder use `SourceDirectorySet.getDestinationDirectory()`

Default with `java-base` plugin:
  ``${project.layout.buildDirectory}`/classes/`${sourceDirectorySet.name}`/`${sourceSet.name}``

#### `DirectoryProperty` `destinationDirectory`

Configure the directory to assemble the compiled classes into.

Default with `java-base` plugin:
  ``${project.layout.buildDirectory}`/classes/`${sourceDirectorySet.name}`/`${sourceSet.name}``

#### `PatternFilterable` `filter` (read-only)

The filter used to select the source from the source directories. These filter patterns are applied after the include and exclude patterns of this source directory set. Generally, the filter patterns are used to restrict the contents to certain types of files, eg `*.java`.

#### ``Set`<`File`>` `srcDirs`

The source directories that make up this set.

Note that filtering via patterns using <UNHANDLED-LINK>#exclude(Spec)</UNHANDLED-LINK> and <UNHANDLED-LINK>#include(Spec)</UNHANDLED-LINK> (or any overload of these methods) only filters files within the `DirectoryTree`s returned by this method and does not filter the set of source directory trees themselves. This result should agree with `SourceDirectorySet.getSrcDirTrees()`.

Does not filter source directories that do not exist.

Default with `java-base` plugin:
  `src/`${sourceSet.name}`/`${sourceDirectorySet.name}``

### Method details

#### `void` `compiledBy`(``TaskProvider`<`T`>` taskProvider, ``Function`<`T`, `DirectoryProperty`>` mapping)

Define the task responsible for processing the source.

#### `SourceDirectorySet` `source`(`SourceDirectorySet` source)

Adds the given source to this set.

#### `SourceDirectorySet` `srcDir`(`Object` srcPath)

Adds the given source directory to this set. The given directory does not need to exist. Directories that do not exist are ignored.

#### `SourceDirectorySet` `srcDirs`(``Object`...` srcPaths)

Adds the given source directories to this set. The given directories do not need to exist. Directories that do not exist are ignored.
