Yes, you missed something. In the {{README}}, it says
{quote}
If this is a source distribution, you can find instructions how to
build the release in the "Building from a source distribution" section
in site/_docs/howto.md.
{quote}
In {{README}}, the only reference to {{README.md}} is
{quote}
README.md contains examples of running Avatica.
{quote}
so I'm not sure why you went there for build instructions.
{quote}
When you get there, it states java 8 or later but trying to build with Java 17
fails.
{quote}
Yes, we should fix that. Until recently we could build on all versions of Java,
but then they released JDK 16 and 17 and we didn't do the necessary to support
them.
> Avatica readme for source release should have better build instructions

> Key: CALCITE-4840
> URL: https://issues.apache.org/jira/browse/CALCITE-4840
> Project: Calcite
> Issue Type: Improvement
> Components: avatica
> Reporter: Jacques Nadeau
> Priority: Major
> Labels: newbie
>
> Right now, trying to figure out how you should build from the source release
> is too difficult (unless I missed something). To find the rather meagre
> instructions, you have to:
> # Open the README and see it says use README.md
> # Open README.md and follow the link to the avatica home
> # Click develop
> # Click avatica development guide link
> # Find and click "build from a source distribution"
> Good luck to someone to find that path :)
> When you get there, it states java 8 or later but trying to build with Java
> 17 fails. For reference, jvm I was using:
> {{% java --version}}
> {{openjdk 17 2021-09-14 LTS}}
> {{OpenJDK Runtime Environment Corretto-17.0.0.35.2 (build 17+35-LTS)}}
> {{OpenJDK 64-Bit Server VM Corretto-17.0.0.35.2 (build 17+35-LTS, mixed mode,
> sharing)}}
>
> Ideally the readme (or an install.md or a single click) should include:
> * Prerequisites to build (gradle 6.8.1 and Java 8?)
> * How to check signature
> * How to build & test
>
