Building CorDapps against a non-release branch

It is advisable to develop CorDapps against the most recent Corda stable release. However, you may need to build a CorDapp against an unstable non-release branch if your CorDapp uses a very recent feature, or you are using the CorDapp to test a PR on the main codebase.

To work against a non-release branch, proceed as follows:

  1. Clone the Corda repository
  2. Check out the branch or commit of the Corda repository you want to work against
  3. Make a note of the gradlePluginsVersion in the root constants.properties file of the Corda repository
  4. Clone the Corda Gradle Plugins repository
  5. Check out the tag of the Corda Gradle Plugins repository corresponding to the gradlePluginsVersion
  6. Follow the instructions in the readme of the Corda Gradle Plugins repository to install this version of the Corda Gradle plugins locally
  7. Open a terminal window in the folder where you cloned the Corda repository
  8. Publish Corda to your local Maven repository using the following commands:
  • Unix/Mac OSX: ./gradlew install
  • Windows: gradlew.bat install

Warning

If you do modify your local Corda repository after having published it to Maven local, then you must re-publish it to Maven local for the local installation to reflect the changes you have made.

Warning

As the Corda repository evolves on a daily basis, two clones of an unstable branch at different points in time may differ. If you are using an unstable release and need help debugging an error, then please let us know the commit you are working from. This will help us ascertain the issue.

  1. Make a note of the corda_release_version in the root build.gradle file of the Corda repository
  2. In your CorDapp's root build.gradle file:
    • Update ext.corda_release_version to the corda_release_version noted down earlier
    • Update corda_gradle_plugins_version to the gradlePluginsVersion noted down earlier
