6.4 Understanding Profiles 5.2.3

(Quick Reference) # 6.4 Understanding Profiles Version: 5.2.3 ## 6.4 Understanding Profiles A profile is a simple directory that contains a `profile.yml` file and directories containing the "commands", "skeleton" and "templates" defined by the profile. Example:
    /web
        commands/
            create-controller.yml
            run-app.groovy
            ...
        features/
            asset-pipeline/
                skeleton
                feature.yml
        skeleton/
            grails-app/
                controllers/
                ...
            build.gradle
        templates/
            artifacts/
                Controller.groovy
        profile.yml
The above example is a snippet of structure of the 'web' profile. The `profile.yml` file is used to describe the profile and control how the build is configured. #### Understanding the profile.yml descriptor The `profile.yml` can contain the following child elements. #### 1) repositories A list of Maven repositories to include in the generated build. Example:
    repositories:
        - "https://repo.grails.org/grails/core"
#### 2) build.repositories A list of Maven repositories to include in the buildscript section of the generated build. Example:
    build:
        repositories:
            - "https://repo.grails.org/grails/core"
#### 3) build.plugins A list of Gradle plugins to configure in the generated build. Example:
    build:
        plugins:
            - eclipse
            - idea
            - org.grails.grails-core
#### 4) build.excludes A list of Gradle plugins to exclude from being inherited from the parent profile:
    build:
        excludes:
            - org.grails.grails-core
#### 5) dependencies A map of scopes and dependencies to configure. The `excludes` scope can be used to exclude from the parent profile. Example:
    dependencies:
        - scope: excludes
          coords: "org.grails:hibernate:*"
        - scope: build
          coords: "org.grails:grails-gradle-plugin:$grailsVersion"
        - scope: compile
          coords: "org.springframework.boot:spring-boot-starter-logging"
        - scope: compile
          coords: "org.springframework.boot:spring-boot-autoconfigure"
##### Excluding Transitive Dependencies To exclude transitive dependencies, define `excludes` key with a List of transitive dependencies Map of the dependency group, module, classifier, and `extension` as:
    dependencies:
        - scope: testCompile
          coords: org.spockframework:spock-core
          excludes:
            - group: org.codehaus.groovy
              module: groovy-all
#### 6) features.defaults A default list of features to use if no explicit features are specified.
    features:
        defaults:
            - hibernate
            - asset-pipeline
#### 7) skeleton.excludes A list of files to exclude from parent profile’s skeletons (supports wildcards).
    skeleton:
        excludes:
            - gradlew
            - gradlew.bat
            - gradle/
#### 8) skeleton.parent.target The target folder that parent profile’s skeleton should be copied into. This can be used to create multi-project builds.
    skeleton:
        parent:
            target: app
#### 9) skeleton.binaryExtensions Which file extensions should be copied from the profile as binary. Inherited and combined from parent profiles.
    skeleton:
        binaryExtensions: [exe, zip]
#### 10) skeleton.executable File patterns that should be marked as executable in the resulting application. Inherited and combined from parent profiles. The patterns are parsed with Ant.
    skeleton:
        executable:
          - "**/gradlew*"
          - "**/grailsw*"
#### 11) instructions Text to be displayed to the user after the application is created
    instructions: Here are some instructions
#### What happens when a profile is used? When the `create-app` command runs it takes the skeleton of the parent profiles and copies the skeletons into a new project structure. The `build.gradle` file is generated is result of obtaining all of the dependency information defined in the `profile.yml` files and produces the required dependencies. The command will also merge any `build.gradle` files defined within a profile and its parent profiles. The `grails-app/conf/application.yml` file is also merged into a single YAML file taking into account the profile and all of the parent profiles. | Quick Reference (hide)
