Remove some information that is way to specific for installing the oracle jdk. Add mention of zulu openjdk to the docs. Specify that the docs will go through how to install the oracle jdk only but provide links to amazon corretto, openjdk and zulu. Also say that we support intellij 2019 which has been released now.

Getting set up for CorDapp development
|
|
======================================
|
|
|
|
Software requirements
|
|
---------------------
|
|
|
|
Corda uses industry-standard tools:
|
|
|
|
* **Java 8 JVM** - we require at least version |java_version|, but do not currently support Java 9 or higher.
|
|
|
|
We have tested with the following builds:
|
|
|
|
* `Oracle JDK <https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html>`_
|
|
|
|
* `Amazon Corretto <https://aws.amazon.com/corretto/>`_
|
|
|
|
* `Red Hat's OpenJDK <https://developers.redhat.com/products/openjdk/overview/>`_
|
|
|
|
* `Zulu's OpenJDK <https://www.azul.com/>`_
|
|
|
|
Please note that OpenJDK builds usually exclude JavaFX, which our GUI tools require.
|
|
|
|
* **IntelliJ IDEA** - supported versions **2017.x**, **2018.x** and **2019.x** (with Kotlin plugin version |kotlin_version|)
|
|
* **Gradle** - we use 4.10 and the ``gradlew`` script in the project / samples directories will download it for you.
|
|
|
|
Please note:
|
|
|
|
* Applications on Corda (CorDapps) can be written in any language targeting the JVM. However, Corda itself and most of
|
|
the samples are written in Kotlin. Kotlin is an
|
|
`official Android language <https://developer.android.com/kotlin/index.html>`_, and you can read more about why
|
|
Kotlin is a strong successor to Java
|
|
`here <https://medium.com/@octskyward/why-kotlin-is-my-next-programming-language-c25c001e26e3>`_. If you're
|
|
unfamiliar with Kotlin, there is an official
|
|
`getting started guide <https://kotlinlang.org/docs/tutorials/>`_, and a series of
|
|
`Kotlin Koans <https://kotlinlang.org/docs/tutorials/koans.html>`_
|
|
|
|
* IntelliJ IDEA is recommended due to the strength of its Kotlin integration.
|
|
|
|
Following these software recommendations will minimize the number of errors you encounter, and make it easier for
|
|
others to provide support. However, if you do use other tools, we'd be interested to hear about any issues that arise.

Next steps
|
|
----------
|
|
First, run the :doc:`example CorDapp <tutorial-cordapp>`.
|
|
|
|
Next, read through the :doc:`Corda Key Concepts <key-concepts>` to understand how Corda works.
|
|
|
|
By then, you'll be ready to start writing your own CorDapps. Learn how to do this in the
|
|
:doc:`Hello, World tutorial <hello-world-introduction>`. You may want to refer to the
|
|
:doc:`API documentation <corda-api>`, the :doc:`flow cookbook <flow-cookbook>` and the
|
|
`samples <https://www.corda.net/samples/>`_ along the way.
|
|
|
