What is the easiest way to use this in Eclipse?

I pitched the use of palantir-java-format to my colleagues, but now I'm facing the issue of on-boarding people who use Eclipse. After exploring the available materials and issue discussions, I understand that there's no way to do it with a few clicks or by installing a plugin.

Thus, my question is: what is the path of minimum resistance for using palantir-java-format with the Eclipse IDE?.

Git hooks come to mind, one could invoke mvn spotless:apply when a commit is made. This is an IDE-agnostic approach, and I like it. However, it disregards Eclipse's formatting tools and keyboard shortcuts - which means that people won't see the auto-formatted code until they commit. Moreover, people's workflow that they developed for ages (write code, format it) will potentially be disrupted because there is no feedback loop.

Is there a way to tell Eclipse to run a given command when a file is saved? What I found so far in Project properties / Java editor / Save actions is not at all CLI-friendly, it can perform some actions from a set of possibilities that Eclipse defined, but there's no way to delegate this process to an arbitrary command.

What are the best practices when it comes to palantir-java-format and Eclipse?

No repository file or test is named. Start with the available project materials and Eclipse's Project properties > Java editor > Save actions, then compare the mentioned git-hook and mvn spotless:apply approaches with Eclipse's save workflow. Done means documenting a practical path for Eclipse users and its trade-offs.
