> To save a lot of CPU and RAM in Eclipse m2e, we're trying to use ProjectBuilder.build(List<File>
projects ...) instead of sequencing multiple Projectbuilder.build(File singleProject...).
This has a big positive impact on m2e.
> However, we noticed that when the operation is failing in some case because pom is incomplete
(which is a pretty usual state in the IDE), the multi-projects methods does not retrn the
MavenProject in the ProjectBuildingException.getResults() while the single-project method
does.
> Adding MavenProject for the multi-project ProjectBuilder.build(...) would allow m2e to
use this method and save ~75% RAM and CPU in many operations.
