I thought I'd try stracing that compilation step to see if it helps.
Some of the relevant snippets:

[pid 10216]
open("/home/mcv21/packages/libxmltooling-java/debian/maven-repo/org/slf4j/slf4j-jdk14/debian/slf4j-jdk14-debian.pom",
O_RDONLY) = 24

i.e. its finding slf4j-jdk14-debian.pom OK within debian/maven-repo (I'm
presuming this is part of the maven-debian-helper magic). Similarly, it
opens slf4j-parent-debian.pom, slf4j-api-debian.pom,
jcl-over-slf4j-debian.pom. All well and good.

Then:

[pid 10216]
open("/home/mcv21/packages/libxmltooling-java/target/classes/org/slf4j",
O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)
[pid 10216] open("./org/slf4j",
O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)

It seems to be this failing command that prompts the "package org.slf4j
does not exist" error.

I hope some of that's of use, but I don't feel I'm any closer to finding
out why this package won't build. Any ideas?

Thanks,

Matthew
