During the generation stage, a pair of auxiliary files is created to help visualizing dependencies between modules. The information they contain is similar but they are presented in a different way. The files are generated in the root of the project folder.
This representation shows all modules and its dependencies as a directed graph in which modules are represented by nodes and dependencies by edges between them. It is stored in the dependencies.dot file and can be can be used with Graphviz. This is an example of the generated graph:
For projects with many inter module dependencies it can be difficult to visualize the dependencies as a graph and it can be convenient to use an adjacency matrix. The file dependencies.png contains an image with it. The colors on the header indicates what type of module it is:
- Blue: App.
- Green: Android module.
- Yellow: Non-android module.
The cells in a particular row indicates the dependencies for that module, while the cell in a column indicate what other modules depoend on it. The type of dependency is also encoded using a color, based on Gradle documentation:
- Black: No dependency.
- Green: user declared dependencies.
- Pink: used when a component compiles, or runs against the library.
- Blue: internal to the component, for its own use.
- White: inherited from the Java plugin.
- Purple: two or more configurations from the Java library plugin configurations.
- Red: one or more configurations, with at least one not from the Java library plugin.
This is the generated image for the project in the example graph:
