Building against MasterΒΆ

When developing a CorDapp, it is advisable to use the most recent Corda Milestone release, which has been extensively tested. However, if you need to use a very recent feature of the codebase, you may need to work against the unstable Master branch.

To work against the Master branch, proceed as follows:

  • Open a terminal window in the folder where you cloned the Corda repository (available here)

  • Use the following command to check out the latest master branch:

    git fetch; git checkout master

  • 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 Milestone releases, as the Milestone 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.
