All gradle commands must be execute at the root of the project directory

Build and deploy steps

  1. Defined components in plugins.properties

  2. Build, test and package

  3. Deploy to project

Explaining each step

Step 1: Define components in plugins.properties

Create a plugins.properties file with a similar definition for your custom class or classes under the resources/META-INF/services directory. If you are packaging more than one component add the definition on a new line.

com.yourdomain.processors.transformers.CustomProcessor

Step 2: Package, test and package

A single project can have a number of custom components which can be packaged into a single or multiple jar files. The template project provides basic grade.build file. The project will execute these tests during the gradle build cycle and deploy to your local maven repository.

Example gradle file

plugins {
    id "java"
    id 'maven-publish'
}

jar.doFirst {
    archiveBaseName = 'mydomain-customtransformer-processor'
    manifest {
        attributes "Class-Path" : configurations.compileClasspath.collect { it.getName() }.join(' ')
    }
}

dependencies {
    implementation "com.fractalworks.streams.platform:fractalworks-stream-platform:$platformVersion"
}

Execute the below command at the project root. This will build, test, package and publish the resulting artifacts to your local maven repository.

gradle build publishToMavenLocal

Step 3: Deploy to project

cp build/libs/<your-component>.jar <location>/userlibs

Once your package has been successfully created you are ready to deploy to a Joule project. The resulting jar artefacts' needs to be placed in to the userlibs directory in your Joule projects directory. See provided examples for further directions.
