Getting into dependency and avoiding dependency hell
As you use a number of dependencies, each of them in turn may also include further dependencies. A situation may come when there are multiple versions of the same dependencies in the project. This can often lead to errors.
Getting ready
To understand this, we need to have a fairly complex project that has several transitive dependencies. You can look at one such project at https://github.com/selendroid/demoproject-selendroid.
Clone the repository on your system. Now, we are ready to see how complex dependencies can get.
How to do it...
Use the following steps to avoid dependency hell:
Run the following command:
mvn dependency:tree -DverboseNote the output as shown in the following screenshot:
How it works...
As you can see, in the course of identifying the dependencies to be used in the project, Maven does a dependency analysis. This reveals two things:
Two or more dependencies require the same version of another dependency. Maven includes a dependency...
