Direct Known Subclasses:

SchemaGenerationMojo, TestSchemaGenerationMojo

public abstract class AbstractXsdGeneratorMojo
extends AbstractJaxbMojo

Abstract superclass for Mojos that generate XSD files from annotated Java Sources. This Mojo delegates execution to the schemagen tool to perform the XSD file generation. Moreover, the AbstractXsdGeneratorMojo provides an augmented processing pipeline by optionally letting a set of NodeProcessors improve the 'vanilla' XSD files.

Field Detail

SCHEMAGEN_EMITTED_FILENAME

public static final Pattern SCHEMAGEN_EMITTED_FILENAME

Pattern matching the names of files emitted by the JAXB/JDK SchemaGenerator. According to the JAXB Schema Generator documentation:

There is no way to control the name of the generated schema files at this time.

STANDARD_JAVADOC_RENDERER

public static final JavaDocRenderer STANDARD_JAVADOC_RENDERER

The default JavaDocRenderer used unless another JavaDocRenderer should be used.

Since:

2.0

See Also:

javaDocRenderer

STANDARD_BYTECODE_EXCLUDE_FILTERS

public static final List<Filter<File>> STANDARD_BYTECODE_EXCLUDE_FILTERS

Default exclude file name suffixes for testSources, used unless overridden by an explicit configuration in the testSourceExcludeSuffixes parameter.

CLASS_INCLUDE_FILTERS

public static final List<Filter<File>> CLASS_INCLUDE_FILTERS

Filter list containing a PatternFileFilter including ".class" files.

SYSTEM_TOOLS_CLASSLOADER_PACKAGES

public static final List<String> SYSTEM_TOOLS_CLASSLOADER_PACKAGES

Specification for packages which must be loaded using the SystemToolClassLoader (and not in the plugin's ThreadContext ClassLoader). The SystemToolClassLoader is used by SchemaGen to process some stuff from the tools.jar archive, in particular its exception types used to signal JAXB annotation Exceptions.

See Also:

ToolProvider.getSystemToolClassLoader()

generateEpisode

@Parameter(defaultValue="true")
protected boolean generateEpisode

Corresponding SchemaGen parameter: episode.

Generate an episode file from this XSD generation, so that other schemas that rely on this schema can be compiled later and rely on classes that are generated from this compilation. The generated episode file is really just a JAXB customization file (but with vendor extensions.)

If this parameter is true, the episode file generated is called META-INF/sun-jaxb.episode, and included in the artifact.

Since:

2.0

See Also:

AbstractJaxbMojo.STANDARD_EPISODE_FILENAME

createJavaDocAnnotations

@Parameter(defaultValue="true")
protected boolean createJavaDocAnnotations

If true, Elements or Attributes in the generated XSD files will be annotated with any JavaDoc found for their respective properties. If false, no XML documentation annotations will be generated in post-processing any results from the JAXB SchemaGenerator.

Since:

2.0

javaDocRenderer

@Parameter
protected JavaDocRenderer javaDocRenderer

A renderer used to create XML annotation text from JavaDoc comments found within the source code. Unless another implementation is provided, the standard JavaDocRenderer used is DefaultJavaDocRenderer.

Since:

2.0

See Also:

DefaultJavaDocRenderer

clearOutputDir

@Parameter(defaultValue="true")
protected boolean clearOutputDir

Removes all files from the output directory before running SchemaGenerator.

Since:

2.0

AbstractXsdGeneratorMojo

public AbstractXsdGeneratorMojo()

Method Detail

shouldExecutionBeSkipped

protected boolean shouldExecutionBeSkipped()

XSD schema files are not generated from POM projects or if no includes have been supplied.

Implement this method to check if this AbstractJaxbMojo should skip executing altogether.

Specified by:

shouldExecutionBeSkipped in class AbstractJaxbMojo

Returns:

true to indicate that this AbstractJaxbMojo should bail out of its execute method.

isReGenerationRequired

protected boolean isReGenerationRequired()

Specified by:

isReGenerationRequired in class AbstractJaxbMojo

Returns:

true to indicate that this AbstractJaxbMojo should be run since its generated files were either stale or not present, and false otherwise.

performExecution

protected boolean performExecution()
                            throws org.apache.maven.plugin.MojoExecutionException,
                                   org.apache.maven.plugin.MojoFailureException

Implement this method to perform this Mojo's execution. This method will only be called if !shouldExecutionBeSkipped() && isReGenerationRequired().

Specified by:

performExecution in class AbstractJaxbMojo

Returns:

true if the timestamp of the stale file should be updated.

Throws:

org.apache.maven.plugin.MojoExecutionException - if an unexpected problem occurs. Throwing this exception causes a "BUILD ERROR" message to be displayed.

org.apache.maven.plugin.MojoFailureException - if an expected problem (such as a compilation failure) occurs. Throwing this exception causes a "BUILD FAILURE" message to be displayed.

getWorkDirectory

protected abstract File getWorkDirectory()

Returns:

The working directory to which the SchemaGenerator should initially copy all its generated files, including bytecode files, compiled from java sources.

getCompiledClassNames

protected abstract List<URL> getCompiledClassNames()

Finds a List containing URLs to compiled bytecode files within this Compilation Unit. Typically this equals the resolved files under the project's build directories, plus any JAR artifacts found on the classpath.

Returns:

A non-null List containing URLs to bytecode files within this compilation unit. Typically this equals the resolved files under the project's build directories, plus any JAR artifacts found on the classpath.

getSources

protected abstract List<URL> getSources()

Override this method to acquire a List holding all URLs to the SchemaGen Java sources for which this AbstractXsdGeneratorMojo should generate Xml Schema Descriptor files.

Specified by:

getSources in class AbstractJaxbMojo

Returns:

A non-null List holding URLs to sources for the XSD generation.
