Because it can break your build at any moment you cannot achive reproducible builds and don t know which version of dependency used by particular version of your app

I dont follow If I have dependencyA which depends on appCompat 28 0 0 and dependencyB which depends on appCompat 27 1 1

ursus · Answer

I run `dependencies` and in the graph its does a or something or arrow of 27 11 gt 28 0 0 something along those lines of overriding the older version to new automatically

This is not using latest this is dependency resolution rule of Gradle but dependencies have static versions

gildor · Answer

Sorry maybe I misunderstood your message I thought that you talking why not use latest version with wildcard

ursus · Answer

no no its okay my question was why is exclude sometimes necessary if gradle can do the above I get it its excluding the transitive dependency if I dont want it but 99 of the time it is used because of some kind of versions conflict but what versions conflict if gradle can bump it as again above

gildor · Answer

There are many different cases For example if you have different versions in different configurations for example compile and testCompile in this case Gradle cannot choose one of them Or you just want to exclude dependency sometimes transitive dependency just not used in your case Also you may have problems if some dependency part of your project hacked version and you exclude it to avoid multiple classes on classpath
