> The {{LifecycleExecutionException}} to report has no project instance. In this particular case, the exception is created in {{DefaultLifecycleExecutor}} by wrapping a {{LifecycleSpecificationException}}. This raises the question whether the class {{LifecycleException}} should provide a field to carry a {{MavenProject}} instance, which could then be propagated to the wrapping exception.
