public Dependency()
```
- Method Detail
  - addExclusion
```
public void addExclusion(Exclusion exclusion)
```
    Method addExclusion.
    
    Parameters:
    
    exclusion -
  - clone
```
public Dependency clone()
```
    Method clone.
    
    Overrides:
    
    clone in class Object
    
    Returns:
    
    Dependency
  - getArtifactId
```
public String getArtifactId()
```
    Get the unique id for an artifact produced by the project group, e.g. maven-artifact.
    
    Returns:
    
    String
  - getClassifier
```
public String getClassifier()
```
    Get the classifier of the dependency. It is appended to the filename after the version. This allows:
    - refering to attached artifact, for example sources and javadoc: see default artifact handlers for a list,
    - distinguishing two artifacts that belong to the same POM but were built differently. For example, jdk14 and jdk15.
    Returns:
    
    String
  - getExclusions
```
public List<Exclusion> getExclusions()
```
    Method getExclusions.
    
    Returns:
    
    List
  - getGroupId
```
public String getGroupId()
```
    Get the project group that produced the dependency, e.g. org.apache.maven.
    
    Returns:
    
    String
  - getLocation
```
public InputLocation getLocation(Object key)
```
    Description copied from interface: InputLocationTracker
    
    Gets the location of the specified field in the input source.
    
    Specified by:
    
    getLocation in interface InputLocationTracker
    
    Parameters:
    
    key -
    
    Returns:
    
    InputLocation
  - getOptional
```
public String getOptional()
```
    Get indicates the dependency is optional for use of this library. While the version of the dependency will be taken into account for dependency calculation if the library is used elsewhere, it will not be passed on transitively. Note: While the type of this field is String for technical reasons, the semantic type is actually Boolean. Default value is false.
    
    Returns:
    
    String
  - getScope
```
public String getScope()
```
    Get the scope of the dependency - compile, runtime, test, system, and provided. Used to calculate the various classpaths used for compilation, testing, and so on. It also assists in determining which artifacts to include in a distribution of this project. For more information, see the dependency mechanism.
    
    Returns:
    
    String
  - getSystemPath
```
public String getSystemPath()
```
    Get fOR SYSTEM SCOPE ONLY. Note that use of this property is discouraged and may be replaced in later versions. This specifies the path on the filesystem for this dependency. Requires an absolute path for the value, not relative. Use a property that gives the machine specific absolute path, e.g. ${java.home}.
    
    Returns:
    
    String
  - getType
```
public String getType()
```
    Get the type of dependency. While it usually represents the extension on the filename of the dependency, that is not always the case. A type can be mapped to a different extension and a classifier. The type often corresponds to the packaging used, though this is also not always the case. Some examples are jar, war, ejb-client and test-jar: see default artifact handlers for a list. New types can be defined by plugins that set extensions to true, so this is not a complete list.
    
    Returns:
    
    String
  - getVersion
```
public String getVersion()
```
    Get the version of the dependency, e.g. 3.2.1. In Maven 2, this can also be specified as a range of versions.
    
    Returns:
    
    String
  - removeExclusion
```
public void removeExclusion(Exclusion exclusion)
```
    Method removeExclusion.
    
    Parameters:

    key -
    
    location -
  - setOptional
```
public void setOptional(String optional)
```
    Set indicates the dependency is optional for use of this library. While the version of the dependency will be taken into account for dependency calculation if the library is used elsewhere, it will not be passed on transitively.

    Parameters:
    
    optional -
  - setScope
```
public void setScope(String scope)
```
    Set the scope of the dependency - compile, runtime, test, system, and provided. Used to calculate the various classpaths used for compilation, testing, and so on. It also assists in determining which artifacts to include in a distribution of this project. For more information, see the dependency mechanism.
    
    Parameters:
    
    scope -
  - setSystemPath
```
public void setSystemPath(String systemPath)
```
    Set fOR SYSTEM SCOPE ONLY. Note that use of this property is discouraged and may be replaced in later versions. This specifies the path on the filesystem for this dependency. Requires an absolute path for the value, not relative. Use a property that gives the machine specific absolute path, e.g. ${java.home}.
    
    Parameters:
    
    systemPath -
  - setType
```
public void setType(String type)
```
    Set the type of dependency. While it usually represents the extension on the filename of the dependency, that is not always the case. A type can be mapped to a different extension and a classifier. The type often corresponds to the packaging used, though this is also not always the case.
