- org.apache.tools.ant.Project

All Implemented Interfaces:

ResourceFactory
```
public class Project
extends 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 void setKeepGoingMode(boolean keepGoingMode)
```
    Set "keep-going" mode. In this mode Ant will try to execute as many targets as possible. All targets that do not depend on failed target(s) will be executed. If the keepGoing settor/getter methods are used in conjunction with the ant.executor.class property, they will have no effect.
    
    Parameters:
    
    keepGoingMode - "keep-going" mode

```
public void setNewProperty(String name,
                           String value)

    Parameters:
    
    name - The name of property to set. Must not be null.
    
    value - The new value of the property. Must not be null.

  - setProjectReference
```
public final void setProjectReference(Object obj)
```
    Set a reference to this Project on the parameterized object. Need to set the project before other set/add elements are called.
    
    Parameters:
    
    obj - the object to invoke setProject(this) on.
  - setProperty
```
public void setProperty(String name,
                        String value)
```
    Set a property. Any existing property of the same name is overwritten, unless it is a user property.
    
    Parameters:
    
    name - The name of property to set. Must not be null.
    
    value - The new value of the property. Must not be null.
  - setSystemProperties
```
public void setSystemProperties()
```
    Add all system properties which aren't already defined as user properties to the project properties.
  - setUserProperty
```
public void setUserProperty(String name,
                            String value)
```
    Set a user property, which cannot be overwritten by set/unset property calls. Any previous value is overwritten.
    
    Parameters:
    
    name - The name of property to set. Must not be null.
    
    value - The new value of the property. Must not be null.

  - toBoolean
```
public static boolean toBoolean(String s)
```
    Return the boolean equivalent of a string, which is considered true if either "on", "true", or "yes" is found, ignoring case.
    
    Parameters:
    
    s - The string to convert to a boolean value.
    
    Returns:
    
    true if the given string is "on", "true" or "yes", or false otherwise.
  - topoSort
```
public final Vector<Target> topoSort(String[] root,
                                     Hashtable<String,Target> targetTable,
                                     boolean returnAll)
                              throws BuildException
```
    Topologically sort a set of targets.
    
    Parameters:
    
    root - String[] containing the names of the root targets. The sort is created in such a way that the ordered sequence of Targets is the minimum possible such sequence to the specified root targets. Must not be null.
    
    targetTable - A map of names to targets (String to Target). Must not be null.
    
    returnAll - boolean indicating whether to return all targets, or the execution sequence only.
    
    Returns:
    
    a Vector of Target objects in sorted order.
    
    Throws:
    
    BuildException - if there is a cyclic dependency among the targets, or if a named target does not exist.
    
    Since:
    
    Ant 1.6.3
  - topoSort
```
public final Vector<Target> topoSort(String root,
                                     Hashtable<String,Target> targetTable)
                              throws BuildException
```
    Topologically sort a set of targets. Equivalent to calling topoSort(new String[] {root}, targets, true).
    
    Parameters:
    
    root - The name of the root target. The sort is created in such a way that the sequence of Targets up to the root target is the minimum possible such sequence. Must not be null.
    
    targetTable - A Hashtable mapping names to Targets. Must not be null.
    
    Returns:
    
    a Vector of ALL Target objects in sorted order.
    
    Throws:
    
    BuildException - if there is a cyclic dependency among the targets, or if a named target does not exist.
  - topoSort
```
public final Vector<Target> topoSort(String root,
                                     Hashtable<String,Target> targetTable,
                                     boolean returnAll)
                              throws BuildException
```
    Topologically sort a set of targets. Equivalent to calling topoSort(new String[] {root}, targets, returnAll).
    
    Parameters:
    
    root - The name of the root target. The sort is created in such a way that the sequence of Targets up to the root target is the minimum possible such sequence. Must not be null.
    
    targetTable - A Hashtable mapping names to Targets. Must not be null.
    
    returnAll - boolean indicating whether to return all targets, or the execution sequence only.
    
    Returns:
    
    a Vector of Target objects in sorted order.
    
    Throws:
    
    BuildException - if there is a cyclic dependency among the targets, or if a named target does not exist.
