Subject [jira] [Commented] (MNG-6448) Need to be able to tell Maven to not bother trying to download particular sources jars
Date Thu, 19 Jul 2018 19:20:00 GMT

    [ https://issues.apache.org/jira/browse/MNG-6448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16549723#comment-16549723

Michael Osipov commented on MNG-6448:
-------------------------------------

You are likely confusing m2eclipse with Maven. Maven never downloads source JARs. Can you
clarify with an example?

>             Project: Maven

> Sources jars are optional, so Maven has no way of knowing if a project decided to publish
a sources jar. Even if the code and released jar hasn't changed since 1998, somebody might
edit the build pom to generate a sources jar.
> This causes Maven to attempt to fetch non-existent sources jars in perpetuity.
> Maven waits several seconds when attempting to fetch a sources jar before giving up.
> We have 142 sourceless jars on our build path.
> The wait time multiplied by 142 winds up adding 11 minutes to our builds.
> We don't want to shut off sources jars, because, when they exist, developers use them
to step through code. But we don't want Maven to keep trying to download sources jars we know
don't exist and are pretty sure will never exist.
> Something like a section in settings.xml for ignoreSourcesJars that allowed us to list
the ones to ignore would be great.
> I'm happy to help with this if someone can point me to where in the code a change like
this needs to be made.
