AbstractJavaGeneratorMojo

public AbstractJavaGeneratorMojo()

Method Detail

isReGenerationRequired

protected boolean isReGenerationRequired()

Java generation is required if any of the file products is outdated/stale.

Specified by:

isReGenerationRequired in class AbstractAdamsMojo

Returns:

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

generateCode

protected abstract boolean generateCode()
                                 throws org.apache.maven.plugin.MojoExecutionException

Generates the actual code.

Returns:

true if successfully generated

Throws:

org.apache.maven.plugin.MojoExecutionException - if code generation fails

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 AbstractAdamsMojo

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.

getSources

protected abstract List<URL> getSources()

Override this method to acquire a List holding all URLs to the sources for which this AbstractJavaGeneratorMojo should generate Java files. Sources are assumed to be in the form given by the sourceType value.

Returns:

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

addGeneratedSourcesToProjectSourceRoot

protected abstract void addGeneratedSourcesToProjectSourceRoot()

Adds any directories containing the generated classes to the appropriate Project compilation sources; either TestCompileSourceRoot or CompileSourceRoot depending on the exact Mojo implementation of this AbstractJavaGeneratorMojo.
