    Platform-independent newline control string.
  - CONTAINS_WHITESPACE
```
public static final Pattern CONTAINS_WHITESPACE
```
    Pattern matching strings containing whitespace (or consisting only of whitespace).
  - STANDARD_EXCLUDE_FILTERS
```
public static final List<Filter<File>> STANDARD_EXCLUDE_FILTERS
```
    Standard excludes Filters for all Java generator Mojos. The List is unmodifiable.
  - staleFileDirectory
```
@Parameter(defaultValue="${project.build.directory}/jaxb2",
           readonly=true,
           required=true)
protected File staleFileDirectory
```
    The directory where the staleFile is found. The staleFile assists in determining if re-generation of JAXB build products is required.
    
    While it is permitted to re-define the staleFileDirectory, it is recommended to keep it below the ${project.build.directory}, to ensure that JAXB code or XSD re-generation occurs after cleaning the project.
    
    Since:
    
    2.0
  - locale
```
@Parameter(required=false)
protected String locale
```
    A Locale definition to create and set the system (default) Locale when the XJB or SchemaGen tools executes. The Locale will be reset to its default value after the execution of XJC or SchemaGen is complete.
    
    The configuration parameter must be supplied on the form language[,country[,variant]], such as sv,SE or fr. Refer to org.codehaus.mojo.jaxb2.shared.environment.locale.LocaleFacet.createFor(String, Log) for further information.
    
    Example (assigns french locale):
```
     
         <configuration>
              <locale>fr</locale>
         </configuration>
     
 
```
    Since:
    
    2.2
    
    See Also:
    
    LocaleFacet.createFor(String, Log), Locale.getAvailableLocales()
  - extraFacets
```
@Parameter(required=false)
protected List<EnvironmentFacet> extraFacets
```
    Defines a set of extra EnvironmentFacet instances which are used to further configure the ToolExecutionEnvironment used by this plugin to fire XJC or SchemaGen.
    
    Example: If you implement the EnvironmentFacet interface in the class org.acme.MyCoolEnvironmentFacetImplementation, its setup() method is called before the XJC or SchemaGen tools are executed to setup some facet of their Execution environment. Correspondingly, the restore() method in your org.acme.MyCoolEnvironmentFacetImplementation class is invoked after the XJC or SchemaGen execution terminates.
```
     
         <configuration>
         ...
              <extraFacets>
                  <extraFacet implementation="org.acme.MyCoolEnvironmentFacetImplementation" />
              </extraFacets>
         ...
         </configuration>

    the configured List of paths from which this AbstractJaxbMojo and its internal toolset (XJC or SchemaGen) should read classes.
    
    Throws:

  - warnAboutIncorrectPluginConfiguration
```
protected void warnAboutIncorrectPluginConfiguration(String propertyName,
                                                     String description)

  - getStaleFileName
```
protected abstract String getStaleFileName()

  - getEncoding
```
protected final String getEncoding(boolean warnIfConfiguredEncodingDiffersFromFileEncoding)
```
    The algorithm for finding the encoding to use is as follows (where the first non-null value found is used for encoding):
    1. If the configuration property is explicitly given within the plugin's configuration, use that value.
    2. If the Maven property project.build.sourceEncoding is defined, use its value.
    3. Otherwise use the value from the system property file.encoding.
    Parameters:
    
    warnIfConfiguredEncodingDiffersFromFileEncoding - Defines if the configured encoding is not equal to the system property file.encoding, emit a warning on the Maven Log (implies that the Maven log has to be warnEnabled).
    
    Returns:
    
    The encoding to be used by this AbstractJaxbMojo and its tools.
    
    See Also:
    
    encoding
  - getEpisodeFile

                       throws org.apache.maven.plugin.MojoExecutionException
```
    Retrieves the JAXB episode File, and ensures that the parent directory where it exists is created.
    
    Parameters:
    
    customEpisodeFileName - null to indicate that the standard episode file name ("sun-jaxb.episode") should be used, and otherwise a non-empty name which should be used as the episode file name.
    
    Returns:
    
    A non-null File where the JAXB episode file should be written.
    
    Throws:
    
    org.apache.maven.plugin.MojoExecutionException - if the parent directory of the episode file could not be created.
  - logSystemPropertiesAndBasedir
```
protected void logSystemPropertiesAndBasedir()
```
    Prints out the system properties to the Maven Log at Debug level.
