Building maven plugin: Caused by: java.lang.ArrayIndexOutOfBoundsException: 3411 …

[Tommy Svensson]

Hello,

I keep getting this exception from maven when building a maven plugin:

Caused by: java.lang.ArrayIndexOutOfBoundsException: 3411

I have no idea what ”3411” means. If it is some error code it is not 
documented. I actually get no hits when googling on ”maven error codes”. 

The relevant parts of the plugin looks like this:

@Mojo(name="doc", defaultPhase = LifecyclePhase.GENERATE_SOURCES)
public class MarkdownDocMavenPlugin extends AbstractMojo {

    /**
     * Provides the options for which generator to run.
     */
    @Parameter
    private GeneratorOptions generatorOptions;

    /**
     * Provides the options for the HTMLGenerator. These are only relevant if
     * generatorOptions.generator == "html".
     */
    @Parameter
    private HTMLGeneratorOptions htmlGeneratorOptions;

    /**
     * Provides the options for the MarkdownGenerator. These are only relevant 
if
     * generatorOptions.generator == "md".
     */
    @Parameter
    private MarkdownGeneratorOptions mdGeneratorOptions;

    /**
     * Provides the options for the PDFGenerator. These are only relevant if
     * generatorOptions.generator == "pdf".
     */
    @Parameter
    private PDFGeneratorOptions pdfGeneratorOptions;

    /**
     * The projects base directory.
     */
    @Parameter(property = "${basedir}”)    private String baseDir; 

…
    /**  
     * Executes this mojo.
     *
     * @throws MojoExecutionException on bad config and other failures.
     */
    public void execute() throws MojoExecutionException {
    }
…

(The formatting got slightly screwed on paste above. )

The following dependencies for maven plugin is used:
<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-plugin-api</artifactId>
    <version>3.0</version>
</dependency>

<!-- dependencies to annotations -->
<dependency>
    <groupId>org.apache.maven.plugin-tools</groupId>
    <artifactId>maven-plugin-annotations</artifactId>
    <version>3.4</version>
    <scope>provided</scope>
</dependency>

So what I’m I missing here that triggers the ArrayIndexOutOfBoundsException ? 
I’m building with maven 3.3.9. 

I googled, googled, and googled, but found no answers. I’m hoping someone can 
explain this. My only other alternative is to go back to javadoc annotations 
and build with maven 3.0.5. 

Thanks!
