Building against MasterΒΆ

It is advisable to develop CorDapps against the most recent Corda stable release. However you may need to build against the unstable Master branch if you are using a very recent feature, or are testing a PR on the main codebase.

To work against the Master branch, proceed as follows:

  1. Open a terminal window in the folder where you cloned the Corda repository
(available here)
  1. Use the following command to check out the latest master branch:

    git checkout master; git pull

  2. Publish Corda to your local Maven repository using the following commands:

  • Unix/Mac OSX: ./gradlew install
  • Windows: gradlew.bat install

By default, the Maven local repository is found at:

  • ~/.m2/repository on Unix/Mac OS X
  • %HOMEPATH%\.m2 on Windows

This step is not necessary when using a stable releases, as the stable releases are published online

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 the Master branch at different points in time may differ. If you are using a Master 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. Update the ext.corda_release_version property in your CorDapp’s root build.gradle file to match the version here: https://github.com/corda/corda/blob/master/build.gradle#L7
