      Swarm plugin 3.3

      Building a Maven project on a node managed by the swarm plugin generates the stack trace at the bottom of this description.

      The part of most interest appears to be this line:

      Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;" the class loader (instance of org/codehaus/plexus/classworlds/realm/ClassRealm) of the current c    lass, org/slf4j/LoggerFactory, and the class loader (instance of org/codehaus/plexus/classworlds/realm/ClassRealm) for resolved class, org/slf4j/impl/StaticLoggerBinder, have different Class objects for the type LoggerFactory; used in the signature

      I noticed that this commit - f3a9b57cdeb986703f8cefc49b0c208f5e846efc - introduced org.slf4j.jcl-over-slf4j:1.7.22, whereas Maven itself uses version 1.7.5 (https://github.com/apache/maven/blob/maven-3.3.9/pom.xml#L65)

      The Maven plugin lists that package as an exclusion, presumably because of the fragility they mention and because it's provided from elsewhere: https://github.com/jenkinsci/maven-plugin/blob/9807ed59d2f4c15c17485589fca5dd0d5fde3741/pom.xml#L393-L396

      Note that non-Maven builds work just fine.
