Initial setup

Learning Objectives

After you have completed this tutorial, you will know how to create two modules containing the required setup to build your CorDapp. You will create the following modules:

  • ledger-utxo-example-apples-app - This is where you will write your application logic.
  • ledger-utxo-example-apples-contract - This is where your object definitions will be placed.

Perform Initial Setup of Your CorDapp

Create two modules in the project’s root directory.

  1. Create the ledger-utxo-example-apples-app module by performing the following steps:

a. Include the following build.gradle:

plugins {
    id 'net.corda.plugins.cordapp-cpb2' version '7.0.1-Gecko'
}

cordapp {
    targetPlatformVersion 999
    minimumPlatformVersion 999
    workflow {
        name "Apples utxo example app"
        versionId 1
        vendor "R3"
    }
}

dependencies {
    cordaProvided 'net.corda:corda-ledger-utxo:5.0.0.523-Gecko1.0'

    cordapp project(':testing:cpbs:ledger-apples-example:ledger-utxo-apples-example-contract')

    // Common and API packages pulled in as transitive dependencies through client
    cordapp 'com.r3.corda.notary.plugin.nonvalidating:notary-plugin-non-validating-client:5.0.0.0-Gecko1.0'
}

b. Create the net.cordapp.utxo.apples.flows package.

  1. Create the ledger-utxo-example-apples-contract module by performing the following steps:

a. Include the following build.gradle:

plugins {
    id 'net.corda.plugins.cordapp-cpb2' version '7.0.1-Gecko'
}

cordapp {
    targetPlatformVersion 999
    minimumPlatformVersion 999
    contract {
        name "Apples utxo example contract"
        versionId 1
        vendor "R3"
    }
}

dependencies {
    cordaProvided 'net.corda:corda-ledger-utxo:5.0.0.523-Gecko1.0'
}

b. Create two packages: net.cordapp.utxo.apples.contracts and net.cordapp.utxo.apples.states.
