Build tools
-----------
In the instructions that follow, we assume you are using ``gradle`` and the ``cordformation`` plugin to build your
CorDapp. See the `example build file <https://github.com/corda/cordapp-template-kotlin/blob/release-V1/build.gradle>`_
from the CorDapp template.
CorDapp. You can find examples of building a CorDapp using these tools in the ``build.gradle`` file of the `Kotlin CorDapp Template <https://github.com/corda/cordapp-template-kotlin>`_ and the `Java CorDapp Template <https://github.com/corda/cordapp-template-kotlin>`_.
Setting your dependencies
-------------------------
Choosing your Corda version
^^^^^^^^^^^^^^^^^^^^^^^^^^^
``ext.corda_release_version`` and ``ext.corda_gradle_plugins_version`` are used in the ``build.gradle`` to define the
versions of Corda and the Corda Gradle Plugins that are used to build your CorDapp.
Choosing your Corda, Quasar and Kotlin versions
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Several ``ext`` variables are used in a CorDapp's ``build.gradle`` file to define which versions are used to build your CorDapp:
For example, to use version 1.0 of Corda and version 1.0 of the Corda gradle plugins, you'd write:
.. sourcecode:: groovy
ext.corda_release_version = '1.0.0'
ext.corda_gradle_plugins_version = '1.0.0'
You can find the latest published version of both here: https://bintray.com/r3/corda.
* ``ext.corda_release_version`` defines the version of Corda
* ``ext.corda_gradle_plugins_version`` defines the version of the Corda Gradle Plugins
* ``ext.quasar_version`` defines the version of Quasar
* ``ext.kotlin_version`` defines the version of Kotlin (if using Kotlin to write your CorDapp)
``corda_gradle_plugins_versions`` are given in the form ``major.minor.patch``. You should use the same ``major`` and
``minor`` versions as the Corda version you are using, and the latest ``patch`` version. A list of all the available
versions can be found here: https://bintray.com/r3/corda/cordapp.
versions can be found here: https://bintray.com/r3/corda/cordapp. If in doubt, you should base yourself on the version numbers used in the ``build.gradle`` file of the `Kotlin CorDapp Template <https://github.com/corda/cordapp-template-kotlin>`_ and the `Java CorDapp Template <https://github.com/corda/cordapp-template-kotlin>`_.
For example, to use version 3.0 of Corda, version 3.0.8 of the Corda gradle plugins, version 0.7.9 of Quasar, and version 1.1.60 of Kotlin, you'd write:
.. sourcecode:: groovy
ext.corda_release_version = 'corda-3.0'
ext.corda_gradle_plugins_version = '3.0.8'
ext.quasar_version = '0.7.9'
ext.kotlin_version = '1.1.60'
In certain cases, you may also wish to build against the unstable Master branch. See :doc:`building-against-master`.
