Now you can inspect the occurrences one by one and check whether you could improve the flow of your dependencies. We can find all the places in the service package, where anything from the vet package is used. Let's look at an example to be more specific. It will look for all the places in one of your classes/packages where the other class/package is used. If you click a cell with dependencies, you can call Find usages for dependencies. You can even refactor your classes directly from the DSM view. Taking ActionĭSM view in IDEA is not only a useful tool to visualize dependencies, but you can also take many useful actions directly from the context menu when right-clicking a cell or package. You can see that class Owner has 15 dependencies on class Pet, while Pet has 5 dependencies on Owner. But something you should be really careful about are cyclic dependencies. So far, we covered only uni-directional dependencies. This way you can see dependencies for all the potential sub-packages or even individual classes. In the DSM view, it is simple, you can expand your packages to see their contents. Which means investigating also dependencies between single classes. This is no doubt useful, but often you need to go into more detail. So far we were working only on package level. The purple cell represents dependencies between the same two packages but in the other direction. The color coding is the same, there is just one new concept. In addition to selecting a whole package, you can also click individual cells.

This can be very important as tightly coupled classes, and modules or even cyclic dependencies mean that your code is very hard to refactor and reuse.ĭependency Structure Matrix (or DSM for short) can help you visualize your dependencies and look for potential problems. It can be used to analyze not only dependencies between packages, but also individual classes. IDEA offers a useful tool to analyze internal dependencies in your project called the Dependency Structure Matrix. This functionality is available only in IntelliJ IDEA Ultimate, not Community edition.
