Adam John Burley commented on MNG-6358:
---------------------------------------
Hi <[~gboue]>,
Thanks for the pointer. I also figured this out myself in the last 24 hours,
and, at least for the purpose of my (non-Internet-facing) build, wrote some
extra lines in that file to get it to build. You can find what I did here:
https://stackoverflow.com/a/48797028/191761 - ideally this should be a toggle
within the Maven build for situations like these.
By the way, as you yourself alluded to, some of the licenses don't download
directly as currently configured, and probably another fix is required for
those (I guess another JIRA issue should be raised). These are:
* https://glassfish.java.net/public/CDDLv1.0.html downloads as a 0KB file (see
"jsr250-api.license" in the distribution). A backup is here:
https://forgerock.org/license/CDDLv1.0.html
* http://www.opensource.org/licenses/mit-license.php currently downloads just
an HTML file containing a 301 redirect (see e.g. "slf4j-api.license" in the
distribution). This is because the actual call is redirecting to
https://opensource.org/licenses/mit-license.php - which is what the Maven build
should actually be downloading
There is a precedent here in terms of lines 32-35 in LICENSE.vm (which you
linked to) rewriting the URL "glassfish.dev.java.net" to "glassfish.java.net".
So something similar needs to be done for the above two bullet points.

> Project: Maven
> Issue Type: Bug
> Components: Bootstrap & Build
> Affects Versions: 3.5.2
> Environment: RHEL 7.4
> JDK 1.8.0_141
> Reporter: Adam John Burley
> Priority: Minor
>
> I am trying to build Maven 3.5.2 from source using Maven 3.0.5. The machine I
> am building on has access to an internal Maven repository, but doesn't have
> access to the Internet.
> The build fails, seemingly because it cannot access {{apache.org}} to
> download the license. But I don't understand why it needs to do this, as the
> license is already contained in file {{apache-jar-resource-bundle}} which is
> retrieved as a Maven dependency.

> The error seems to be caused by Apache Velocity invoking a method to retrieve
> the file via reflection. But I am not sure why this is, because I can't find
> any Velocity templates with this reflective method call inside.
> Incidentally, if I disable the plugin using "-Dremoteresources.skip=true",
> the build succeeds. So it's definitely something caused by the way this
> plugin is configured.
