Subject [jira] [Commented] (ARIES-1792) blueprint-maven-plugin slows down compilation
Date Tue, 24 Apr 2018 10:41:00 GMT

    [ https://issues.apache.org/jira/browse/ARIES-1792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16449616#comment-16449616

Xavier Roussel commented on ARIES-1792:
---------------------------------------

I understand the ClassLoader needs to access the classes but the ClassFinder doesn't needs
to scan all the artifacts for annotation, that's why you can ( and need ) to add all the
artifacts to the ClassLoader but only filtered artifacts to the ClassFinder.

It doesn't make sense to add the artifact to the include pattern because following this logic
all the artifacts linked to my module are required by my module so I will have to add all
of them to the includepattern and the filers will be useless ...

More if I add the artifact(s) to the includepattern it will be scanned by the ClassFinder
for annotations, which is exactly what consume time during compilation.

Try out my branch, you will see that everything works fine like that.

> We have a maven project with 20+ modules all using BMP to generate blueprint file.
> During compilation, BMP is executed on each module and represents more than 70% of the
project's compilation time.
> We specify a scanPath for each module as a parameter to BMP but it seems that it scan
the module and also all the dependencies so because the modules are linked together, the whole
project is scanned again and again for each module.
> It could be useful to add an option to exclude dependencies so that BMP only scan the
current module.
