Hi,

I currently cannot get maven, because maven-core fails to build. To reproduce:

    guix shell maven

Log:

bug#55776: maven-core fails to build

[Remco van 't Veer]

I did some digging and found this regression is caused by commit:

 6068b83b82475566acd4162467bcf54270f338f9
 "gnu: java-jdom: Update to 2.0.6.1 [fixes CVE-2021-33813]."

Apparently the fix for this issue causes jdom to be very strict;

> java.io.IOException: Invalid input descriptor for merge:
> /tmp/plexus-metadata3957336728290309540xml -->
> http://xml.org/sax/features/external-general-entities feature
> http://xml.org/sax/features/external-general-entities not supported
> for SAX driver org.codehaus.plexus.metadata.merge.Driver

Which sound familiar when looking at that CVE
(https://github.com/advisories/GHSA-2363-cqg2-863c):

> An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to

I dunno how to fix this though, I'm just a curious guixer.  Easiest path
seems to be to make a new java-jdom-2.0.6 var and use that as a
native-input for maven.  Would that be an acceptable solution?

Cheers,
Remco

Like you say, the issue is with the new jdom. Believe it or not, but
between 2.0.6 and 2.0.6.1 there's some breakage (and > 1 year of
changes, too)!

So I figured I could fix java-plexus-component-metadata that we use to
generate some xml files during the build of maven. jdom is one of its
inputs. Adding another jdom to the native inputs would probably not fix
the issue.

What I did instead is, since jdom wants to set more features than
supported in the driver, to add dummy support for all these additional
features by just not throwing the exception. It's not very satisfying,
but it works and we don't keep a vulnerable jdom around. With the
attached patch, I built up to maven.

Reverting the jdom upgrade patch, I did get mave-core to build.  I admit
I did not try running it.  My interest in maven is as a dependency to
clojure-tools, I don't really know how to test maven is actually working
by itself.

Smart!  I look forward to seeing your patch land in the main branch.

Thank you!

The patch looks clear enough — will you push it?

Best wishes,

Work for me as well.  Probably can be merged to master?

bug#55776: maven-core fails to build

[Steve George]

Hi,

I was able to build java-plexus-component-metadata using this patch, and 
from there maven to clojure-tools.

Cheers,
