Configuration for jalview project in IntelliJ IDEA IDE

IntelliJ IDEA is a popular IDE for working with Java (and other) code based projects. Some developers may want to work using IDEA instead of Eclipse. The main concern would be CodeStyle configuration, however the same configuration for Eclipse can be imported (and exported) from IDEA. This is not necessarily an exact match of codestyle but could/should be close enough. If combined with spotless this shouldn't pose a problem.

Gradle provides a plugin to automatically generate IDEA configuration files for the project. This is not as dynamic as the Eclipse/Buildship but is a good starting point for providing a way of configuring a jalview project for IDEA, thus providing a development environment for more coders.
