Prior to this commit, the lookup for an ApplicationModule would find modules solely depending on the reference string starting with the base package. That means that a module with base package com.acme.foo, a request for com.acme.foobar would've resulted in a positive match, which of course is wrong.
We now match against either the module's base package or against the reference starting with the base package followed by a dot.
The default for @ApplicationModule(allowedDependencies) is now a single element list with a dedicated token we recognize as "all dependencies allowed". This allows users to declare an empty array explicitly to disallow any outgoing dependencies for an application module. Previously, such a declaration would have allowed any dependency.
We now properly check whether one of a Spring bean's implemented interfaces is exposed by the module before including it in the default rendering of the Application Module Canvas.
The previous modularity verification arrangement assumed the default module detection strategy to be used. To properly support alternative implementations during the verification we now use a dedicated SliceAssignment implementation that assigns types to slices identified by the module they are located in.
Type based named interfaces on types declared in a module's API package still caused the type to be included in the unnamed interface. This is now fixed by explicitly removing named interface types from the unnamed interface.
We now also detect API package types assigned to a named interface without an explicit name as the package name defaulting doesn't work in this case.
Furthermore, named interfaces are now sorted alphabetically to make the unnamed one always appear first.
Both package- and type-level declarations now use the local package name as the named interface's name. This allows to, at the same time, easily declared named interfaces based on packages but also a nice decoupling of the interface definition and the package layout as individual types can be assigned to such interfaces no matter where they are actually declared.
Introduced ApplicationModulesExporter to render an ApplicationModules instances as JSON directly. To avoid a dependency to a JSON library and as we only have to be able to render rather simple arrangements, we just build up the JSON string ourselves.
ApplicationModulesEndpoint now caches the structure calculated once to avoid repeated work.
ModulithMetadata refers to SpringBootApplication in its Javadoc, which requires us to have the JAR on the classpath for Javadoc creation as the linting otherwise fails.
