jackson-module-scala CreatorTest fail using maven, java 1.7, scala 2.11.8

[Steve A.]

I'm trying to compile jackson-scala-module 2.8.3 using a Maven pom.xml file I created based upon the build.sbt file with Java 1.7 and Scala 2.11.8. 

However, line 81 of src/test/scala/com/fasterxml/jackson/module/scala/deser/CreatorTest.scala fails with the following:

Creators should work with static method creator(com.fasterxml.jackson.module.scala.deser.CreatorTest)  Time elapsed: 0-.045 sec  <<< ERROR!

com.faster.jackson.databind.JsonMapingException: Could not find creator property with name 'value' (in class com.fasterxml.jackson.module.scala.deser.ValueHolder)

 at [Source: "2"; line: 1, column: 1]

...

Any idea what could be the problem?

Not without seeing more of the POM. As an aside, what is the motivation for this work?

The motivation is that I'm trying to upgrade a client's system on a closed intranet (i.e. air-gap'd from Github) from Scala 2.10.4 and jackson-module-scala_2.10-2.3.2 for which they modified the source code to not include lazy values and replace nulls with None among other things.  And, Maven is the standard build tool; i.e. sbt is not used.

As far as the pom.xml, basically I added the following to https://repo1.maven.org/maven2/com/fasterxml/jackson/module/jackson-module-scala_2.11/2.8.3/jackson-module-scala_2.11-2.8.3.pom:

Some syntax errors aside, that looks more or less reasonable, and I don't know why that particular test would be failing, given the same code passes using sbt. My only guess is that the change in build platform is somehow tickling some order-dependent bug in creator detection, either in the Scala module or in Jackson Databind. It will probably take a fair amount of break-point debugging in the code to track it down. I don't have the bandwidth to work on it, but if you have questions about how the code works, I'll do my best to answer them.
