Although it is very easy to add dependencies via Maven or Gradle, this does not prevent you from shooting yourself into the foot. You have to manage dependencies, including transitive ones. If the application has too many conflicting dependencies, then use classloader isolation (e.g. OSGi).

It is a littlebit sad, that there are no javac warnings enabled by default that at least check known classes for conflicts in the classpath. An IDE should do that by default, too.
