Plugin Implementation

To use the plugin you need Gradle version 6.9 or later, to start add the following section into your build.gradle file.

plugins {
    id "co.com.bancolombia.cleanArchitecture" version "2.4.3"
}

Or if is a new project execute this script in the root directory of your project.

echo "plugins {
    id \"co.com.bancolombia.cleanArchitecture\" version \"2.4.3\"
}" > build.gradle

To use the plugin you need Gradle version 6.9 or later, to start add the following section into your build.gradle.kts file.

plugins {
    id("co.com.bancolombia.cleanArchitecture") version "2.4.3"
}

Or if is a new project execute this script in the root directory of your project.

echo "plugins {
    id(\"co.com.bancolombia.cleanArchitecture\") version \"2.4.3\"
}" > build.gradle.kts

Tasks

The Scaffolding Clean Architecture plugin will allow you run 8 tasks:

Generate Project

The cleanArchitecture | ca task will generate a clean architecture structure in your project, this task has four optional parameters; package , type, name and coverage. If you run this task on an existing project it will override the main.gradle, build.gradle and gradle.properties files.

package = <package.we.need>: You can specify the main or default package of your project. Default Value = co.com.bancolombia
type = <imperative | reactive>: With this parameter the task will generate a POO project. Default Value = imperative
name = NameProject: This parameter is going to specify the name of the project. Default Value = cleanArchitecture
coverage = <jacoco | cobertura>: This parameter is going to specify the coverage tool for the project. Default Value = jacoco
lombok = <true | false>: Specify if you want to use this plugin . Default Value = true
metrics = <true | false>: Specify if you want to enable this feature with micrometer . Default Value = true
language = <JAVA | KOTLIN>: Specify if you want to use this plugin . Default Value = JAVA
javaVersion = <VERSION_1_8 | VERSION_11 | VERSION_17>: Java version . Default Value = VERSION_11

gradle cleanArchitecture --package=co.com.bancolombia --type=imperative --name=NameProject --coverage=jacoco --lombok=true
gradle ca --package=co.com.bancolombia --type=imperative --name=NameProject --coverage=jacoco --lombok=true

The structure will look like this for java:

      gradle gat

Karate is an open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed.

The validateStructure | vs Validate that project references aren't violated.

   gradle validateStructure
   gradle vs

Delete Module

The deleteModule | dm task will delete a sub project, this task has one required parameter module.

   gradle deleteModule --module=[name]
   gradle dm --module=[name]

Update Project

The updateCleanArchitecture | u task will update plugin and dependencies in all sub projects, this task has one optional parameter dependencies if you only want to update some dependencies the dependency need to contain the group, and the artifact for example for the dependency cleanArchitecture you will need to append co.com.bancolombia:cleanArchitecture. It also updates the spring, lombok, gradle and some other dependencies according to the plugin version that you are using, ocassionally it could make changes in other project structural files. We recommend that you commit your changes to git before running this command, but you can skip the verification passing --git false.

   gradle updateCleanArchitecture --dependencies=[dependency1, dependency2, ...]
   gradle u --dependencies=[dependency1, dependency2, ...]
