Re: ScriptContentTest unit tests failing for ext-email - SLF4J and Ant class loading problems?

Yes - maven is what runs everything for the email-ext plugin. Searching 
found me a couple posts about the same error - and it was a class path 
setup problem with multiple bundled versions of JUnit.

Ugh, maybe there's a hidden junit.jar somewhere. The MethodRule is 
deprecated as of JUnit 4.7 - but somehow the JenkinsRule is failing the 
validation in 
org.junit.runners.BlockJUnit4ClassRunner.validateRuleField(BlockJUnit4ClassRunner.java:181)


  179           private void validateRuleField(Field field, List<Throwable> 
errors) {
  180                   if 
(!MethodRule.class.isAssignableFrom(field.getType()))  181                      
     errors.add(new Exception("Field " + field.getName()
  182                                           + " must implement 
MethodRule"));
  183                   if (!Modifier.isPublic(field.getModifiers()))
  184                           errors.add(new Exception("Field " + 
field.getName()
  185                                           + " must be public"));
  186           }
