gradle-plugin-classycle

This is a gradle plugin for the java classycle dependency checker. The current version works with the latest stable version 1.4.2 from the original homepage.

This plugin needs the gradle javaPlugin to be loaded first.

Per default this plugin expects a dependency definition file at etc/classycle/dependencies.ddf and creates a gradle task classycleMain for the main java sourceSet.

Of course you can set the location of the definition file and scan other sourceSets as well (see usage-section below).

For every sourceSet specified this plugin will create its own task, named classycle<>SourceSetName<>. These tasks depend on the execution of the related "classes" task (e.g. classycleMain depends classes and classycleTest depends testClasses).

For convenience reasons an additional task classycle is created which executes every single sourceSet-specific classycle task.

The Java check task is altered and depends on the classycle task.

Usage

plugins {
    id 'java'
    id 'de.otto.classycle' version '1.4'
}

// if you want to override the default config, otherwise you can omit this section
classycleConfig {
    definitionFile = 'etc/classycle/dependencies.ddf'
    sourceSets = [project.sourceSets.main]
}

Example definition file

A definition file for a spring-boot based microserive might look like this

# Base packages
#----------------------------------------------
{root} = com.example.project.root.package.path
[root] = ${root}.*

# Independence of Architecture-Layers
#----------------------------------------------
[domain] = ${root}.domain.*
[service] = ${root}.service.*
[web] = ${root}.web.*

check sets [domain] [service] [web]

check [domain] independentOf [service]
check [domain] independentOf [web]

check [service] independentOf [web]
