[m2e-users] Debugging plugin execution errors

[Alan Egerton <eggyal@xxxxxxxxx>]

Dear m2e-users,

I am struggling to understand why a plugin is failing to execute.  The
error I receive is "Error executing
(org.bsc.maven:maven-processor-plugin:2.0.5:process:process:generate-sources)",
but no further detail is given.  How can one debug plugin execution to
discover more about WHY a plugin failed to execute?

I am using m2e 1.1.0 on Eclipse Indigo 3.7.2.  The relevant parts of
my pom.xml are given below.

Thank you in advance for your help.

Kind regards,
-- Alan
