Project (Gradle API 2.0)

All Superinterfaces:

Comparable<Project>, ExtensionAware, PluginAware
```
public interface Project
extends Comparable<Project>, ExtensionAware, PluginAware
```
This interface is the main API you use to interact with Gradle from your build file. From a Project, you have programmatic access to all of Gradle's features.

Lifecycle

There is a one-to-one relationship between a Project and a "build.gradle" file. During build initialisation, Gradle assembles a Project object for each project which is to participate in the build, as follows:
- Create a Settings instance for the build.
- Evaluate the "settings.gradle" script, if present, against the Settings object to configure it.
- Use the configured Settings object to create the hierarchy of Project instances.
- Finally, evaluate each Project by executing its "build.gradle" file, if present, against the project. The project are evaluated in breadth-wise order, such that a project is evaluated before its child projects. This order can be overridden by calling evaluationDependsOnChildren() or by adding an explicit evaluation dependency using evaluationDependsOn(String).
Tasks

A project is essentially a collection of Task objects. Each task performs some basic piece of work, such as compiling classes, or running unit tests, or zipping up a WAR file. You add tasks to a project using one of the create() methods on TaskContainer, such as TaskContainer.create(String). You can locate existing tasks using one of the lookup methods on TaskContainer, such as TaskCollection.getByName(String).

Dependencies

A project generally has a number of dependencies it needs in order to do its work. Also, a project generally produces a number of artifacts, which other projects can use. Those dependencies are grouped in configurations, and can be retrieved and uploaded from repositories. You use the ConfigurationContainer returned by getConfigurations() method to manage the configurations. The DependencyHandler returned by getDependencies() method to manage the dependencies. The ArtifactHandler returned by getArtifacts() method to manage the artifacts. The RepositoryHandler returned by getRepositories() method to manage the repositories.

Multi-project Builds

Projects are arranged into a hierarchy of projects. A project has a name, and a fully qualified path which uniquely identifies it in the hierarchy.
Properties

Gradle executes the project's build file against the Project instance to configure the project. Any property or method which your script uses is delegated through to the associated Project object. This means, that you can use any of the methods and properties on the Project interface directly in your script.
For example:
```
 defaultTasks('some-task')  // Delegates to Project.defaultTasks()
 reportsDir = file('reports') // Delegates to Project.file() and the Java Plugin
 
```
You can also access the Project instance using the project property. This can make the script clearer in some cases. For example, you could use project.name rather than name to access the project's name.
A project has 5 property 'scopes', which it searches for properties. You can access these properties by name in your build file, or by calling the project's property(String) method. The scopes are:
- The Project object itself. This scope includes any property getters and setters declared by the Project implementation class. For example, getRootProject() is accessible as the rootProject property. The properties of this scope are readable or writable depending on the presence of the corresponding getter or setter method.
- The extra properties of the project. Each project maintains a map of extra properties, which can contain any arbitrary name -> value pair. Once defined, the properties of this scope are readable and writable. See extra properties for more details.
- The extensions added to the project by the plugins. Each extension is available as a read-only property with the same name as the extension.
- The convention properties added to the project by the plugins. A plugin can add properties and methods to a project through the project's Convention object. The properties of this scope may be readable or writable, depending on the convention objects.
- The tasks of the project. A task is accessible by using its name as a property name. The properties of this scope are read-only. For example, a task called compile is accessible as the compile property.
- The extra properties and convention properties inherited from the project's parent, recursively up to the root project. The properties of this scope are read-only.
When reading a property, the project searches the above scopes in order, and returns the value from the first scope it finds the property in. If not found, an exception is thrown. See property(String) for more details.

When writing a property, the project searches the above scopes in order, and sets the property in the first scope it finds the property in. If not found, an exception is thrown. See setProperty(String, Object) for more details.
Extra Properties
All extra properties must be defined through the "ext" namespace. Once an extra property has been defined, it is available directly on the owning object (in the below case the Project, Task, and sub-projects respectively) and can be read and updated. Only the initial declaration that needs to be done via the namespace.
```
 project.ext.prop1 = "foo"
 task doStuff {
     ext.prop2 = "bar"
 }
 subprojects { ext.${prop3} = false }
 
```
Reading extra properties is done through the "ext" or through the owning object.
```
 ext.isSnapshot = version.endsWith("-SNAPSHOT")
 if (isSnapshot) {
     // do snapshot stuff
 }
 
```
Dynamic Methods

A project has 5 method 'scopes', which it searches for methods:
- The extensions added to the project by the plugins. Each extension is available as a method which takes a closure or Action as a parameter.
- The convention methods added to the project by the plugins. A plugin can add properties and method to a project through the project's Convention object.
- The tasks of the project. A method is added for each task, using the name of the task as the method name and taking a single closure or Action parameter. The method calls the Task.configure(groovy.lang.Closure) method for the associated task with the provided closure. For example, if the project has a task called compile, then a method is added with the following signature: void compile(Closure configureClosure).
- The methods of the parent project, recursively up to the root project.

Resolves a file path to a URI, relative to the project directory of this project. Evaluates the provided path object as described for file(Object), with the exception that any URI scheme is supported, not just 'file:' URIs.

Parameters:
path - The object to resolve as a URI.

Returns:
The resolved URI. Never returns null.

relativePath
```
String relativePath(Object path)
```
Returns the relative path from the project directory to the given path. The given path object is (logically) resolved as described for file(Object), from which a relative path is calculated.

Parameters:
path - The path to convert to a relative path.

Returns:
The relative path. Never returns null.

files
```
ConfigurableFileCollection files(Object... paths)
```
Returns a ConfigurableFileCollection containing the given files. You can pass any of the following types to this method:
- A CharSequence, including String or GString. Interpreted relative to the project directory, as per file(Object). A string that starts with file: is treated as a file URL.
- A File. Interpreted relative to the project directory, as per file(Object).
- A URI or URL. The URL's path is interpreted as a file path. Currently, only file: URLs are supported.
- A Collection, Iterable, or an array. May contain any of the types listed here. The elements of the collection are recursively converted to files.
- A FileCollection. The contents of the collection are included in the returned collection.
- A Callable. The call() method may return any of the types listed here. The return value of the call() method is recursively converted to files. A null return value is treated as an empty collection.
- A Closure. May return any of the types listed here. The return value of the closure is recursively converted to files. A null return value is treated as an empty collection.
- A Task. Converted to the task's output files.
- A TaskOutputs. Converted to the output files the related task.
- An Object. Its toString() value is treated the same way as a String, as per file(Object). This has been deprecated and will be removed in the next version of Gradle.
The returned file collection is lazy, so that the paths are evaluated only when the contents of the file collection are queried. The file collection is also live, so that it evaluates the above each time the contents of the collection is queried.

The returned file collection maintains the iteration order of the supplied paths.
Parameters:
paths - The paths to the files. May be empty.

Returns:
The file collection. Never returns null.

   from tarTree(resources.gzip('someTar.ext'))

   //in case you work with unconventionally compressed tars
   //you can provide your own implementation of a ReadableResource:
   //from tarTree(yourOwnResource as ReadableResource)

       //using ant checksum task to store the file checksum in the checksumOut ant property
       checksum(property: 'checksumOut', file: 'someFile.txt')

       //we can refer to the ant property created by checksum task:
       println "The checksum is: " + checksumOut
     }

     //we can refer to the ant property later as well:
     println "I just love to print checksums: " + ant.checksumOut
   }
 }

Consider following example of ant target:

 <target name='printChecksum'>
   <checksum property='checksumOut'>
     <fileset dir='.'>
       <include name='agile.txt'/>
     </fileset>
   </checksum>
   <echo>The checksum is: ${checksumOut}</echo>
 </target>

Here's how it would look like in gradle. Observe how the ant XML is represented in groovy by the ant builder

 task printChecksum {
   doLast {
     ant {
       checksum(property: 'checksumOut') {
         fileset(dir: '.') {
           include name: 'agile1.txt'
