Last I checked we could download jai-core from maven, it is a bit of an odd situation as it is a binary distribution license (not open source).
For a while maven eas being careful to only distribute things like that as a pom.xml (giving you instructions to install the jar into your local repository yourself). However search of maven central seems okay: - https://search.maven.org/artifact/javax.media/jai_core/1.1.3/jar - search result - https://repo1.maven.org/maven2/javax/media/jai_core/1.1.3/ - browse page -- Jody Garnett On Sun, 14 Feb 2021 at 20:02, Hugh Saalmans <hugh.saalm...@iag.com.au> wrote: > Thanks Jody, > > > > The Apache Sedona team have subsequently provided an alternative to using > a shaded JAR; by adding code to your script to download the GeoTools JARs > on demand when you start an Apache Spark session.
