How to determine which Maven dependency is needing a missing dependency?

Question

I am trying to build an old Maven project and I'm getting the error:

[ERROR] Failed to execute goal on project myapp: Could not resolve dependencies for project com.initech.myapp:war:${buildVersion}: Failure to find tangosol:tangosol-coherence:jar:3.3-rc1 in http://mvnrepo.initech.com/archiva/repository/initechrepo was cached in the local repository, resolution will not be reattempted until the update interval of initechrepo has elapsed or updates are forced -> [Help 1]

I looked in the pom.xml of MyApp and there is no mention of "tangosol" and there is no parent POM so I figure this must be a transitive dependency.

Normally, I can use the Maven Dependency plugin on the command line with mvn dependency:tree to display transitive dependencies. However, since the dependency is missing, the build fails and errors out instead of displaying the tree.

How can I get the cause of missing transitive dependency even if the build is failing?

EDIT: I am aware of why it failed, the artifact is missing from our local repository and the central repository, the question is which of my dependencies is asking for it.

There should be a better way, but if you run the command in debug mode (ie -X so the full command becomes mvn -X dependency:tree) then you'll see the trace printed out before the build dies:

    ...
[DEBUG]    org.springmodules:spring-modules-cache:jar:0.9:compile
[DEBUG]       opensymphony:oscache:jar:2.3:compile
[DEBUG]       tangosol:tangosol-coherence:jar:3.3-rc1:compile
[DEBUG]       oro:oro:jar:2.0.8:compile
[DEBUG]       org.apache.jcs:jcs:jar:1.3:compile
[DEBUG]          concurrent:concurrent:jar:1.0:compile
    ...

better answers are welcome.
