Project (Apache Ant API)

java.lang.Object
- org.apache.tools.ant.Project

All Implemented Interfaces:

ResourceFactory
```
public class Project
extends java.lang.Object
implements ResourceFactory
```
Central representation of an Ant project. This class defines an Ant project with all of its targets, tasks and various other properties. It also provides the mechanism to kick off a build using a particular target name.
This class also encapsulates methods which allow files to be referred to using abstract path names which are translated to native system file paths at runtime.

public static java.lang.String translatePath(java.lang.String toProcess)
```
    Deprecated. since 1.7 Use FileUtils.translatePath instead.
    
    Translate a path into its native (platform specific) format.
    This method uses PathTokenizer to separate the input path into its components. This handles DOS style paths in a relatively sensible way. The file separators are then converted to their platform specific versions.
    
    Parameters:
    
    toProcess - The path to be translated. May be null.
    
    Returns:
    
    the native version of the specified path or an empty string if the path is null or empty.
