added option (enabled by default) to execute gradle integration tests with --stacktrace
renamed pmdcpd plugin to cpd in preparation for upcoming content refactoring
Fixed https://github.com/BancVue/GradlePluginsCore/issues/30 - maven extended publication will now publish transitive dependencies from modules in a multi-module build
refactored cpd plugin to work with multi-project parallelized builds by limiting the plugin to only the root project since CPD is not thead-safe.
in addition, the pmd plugin is no longer applied by the cpd plugin, allowing it to be used independently.
