Are build instructions available?

In the README file says:

> "An Ant build file (build.xml) is provided"

but there is no such file.

It appears that Gradle should be used.

Gradle build creates dist/jalview.jar but it then fails to find dependencies when run according to the README instructions:

$ /usr/local/openjdk11/bin/java -classpath work/jalview/dist/* jalview.bin.Jalview
Java version: 11.0.10

What is wrong?
