Just do the same procedure as in "Adding new dependencies", but with a new version number!
You can also safely delete the old version of the dependency, as nothing will depend on it anymore.
#### Why the suffix `bcv`?
Some dependencies may have been modified or could be released by their author in the future. To avoid confusion and dependency clashes in the local repository, the suffix is a nice way to ensure, the right dependency is used in every project (`bcv` = `ByteCode Viewer` btw).
-`dx`: Just taken from build-tools without modifications
-`Dex2Jar`: Compiled from scratch ([This fork](https://github.com/ThexXTURBOXx/dex2jar)); just take all individual jars from the subprojects and merge them without adding any external dependencies
