gnodet opened a new pull request, #11529:
URL: https://github.com/apache/maven/pull/11529
When multiple model parsers are registered (e.g., for YAML or TOML POMs) and
all parsers fail to parse a POM file, the error message now provides detailed
information about each parser's failure.
### Changes
- Changed `modelParsers` from `List<ModelParser>` to `Map<String,
ModelParser>` to preserve parser names for better error messages
- Added `buildDetailedErrorMessage()` method that generates a comprehensive
error report including:
- The POM file path
- The number of parsers attempted
- Each parser's error with line/column information when available
- The default XML reader's error
- Updated all call sites to use `Map.of()` instead of `List.of()`
- Added unit tests for the new error reporting functionality
### Example Error Output
When a YAML POM file fails to parse:
```
Unable to parse POM /path/to/pom.yaml
Tried 2 parsers:
yaml) YAML parsing failed at line 5, column 10: Invalid YAML syntax
toml) TOML parsing failed at line 3, column 7
default) XML reader also failed: XML parsing failed
```
This improves debugging when using alternative POM formats by showing
exactly why each parser failed, rather than just the final XML error.
