• Configuring

Downloading

1. To obtain the Corda 5.2 CorDapp template, clone the cordapp-template-kotlin repository or cordapp-template-java repository:

   • Kotlin
   • Java

   git clone https://github.com/corda/cordapp-template-kotlin.git <local-folder>
   

   git clone https://github.com/corda/cordapp-template-java.git <local-folder>
   

2. Browse to the new folder and checkout the 5.2 branch:

   git checkout release-V5.2
   

3. Change the remote repository so that you do not inadvertently push your work back to the R3 repository:

   git remote remove origin
   git remote add origin <remote-url>
   

   where <remote-url> is the URL of your remote repository that you have created.

4. Open the project in IntelliJ and let the import process complete. When complete, the project structure looks as follows:

   

Configuring

The CorDapp template includes Gradle tasks to manage a local deployment of Corda. This section describes how to configure Gradle for your installation and contains the following:

• Corda Version
• Java Version

Corda Version

The gradle.properties file specifies the Corda version that the Gradle tasks use. Update the version by setting cordaNotaryPluginsVersion to the Corda version. For example, for Corda 5.2:

cordaNotaryPluginsVersion=5.2.0.0

Java Version

The Corda runtime Gradle tasks require Java Azul Zulu 17. To configure IntelliJ to use the correct Java version for Gradle:

1. Set Gradle JVM to Project SDK 17, via File > Settings > Build, Execution, Deployment > Build Tools > Gradle.

   

2. Update the Java version in the build.gradle file:

   

If using IntelliJ IDEA version 2023.1.4 or greater, you should instead set the environmental variable JAVA_HOME to point to your installation of Java Azul Zulu 17.
