Metadata Generation Issue with Plexus Plugin for Checker Framework Annotations

[Rohan Jha]

Description: I am encountering an issue with the Plexus Component Metadata plugin in my Maven project. The plugin is failing to generate metadata for correct Java syntax when using Checker Framework annotations, particularly @ArrayLen.

Problem Description: The issue arises with the @ArrayLen annotation and potentially other Checker Framework annotations. Despite using correct Java syntax, the Plexus Component Metadata plugin fails to generate the necessary metadata.

Error Messages:  Error generating metadata: : Failed to extract descriptors: syntax error @[43,40] in file:/home/rohanjha/OpenSourcProjects/checkstyle/src/main/java/com/puppycrawl/tools/checkstyle/DefaultConfiguration.java -> [Help 1]

Referred line :

 /** Constant for optimization. */

private static final Configuration @ArrayLen(0) [] EMPTY_CONFIGURATION_ARRAY =
new Configuration[0];

Environment Details:

• Maven version: 3.8.4
• Plexus Component Metadata Plugin version: 2.2.0
• Checker Framework version: 3.44.0
• Java version: 11
• Operating System: Ubuntu 20.04
