Eclipse can have a tendency to hang sometimes for no apparent reason (usually because of memory). Just try restarting it and see if the problem persists. I've encountered this before and restarting Eclipse or the PC altogether usually solves it.

In my case, I increased values of -Xms and -Xmx args to 512 and 2048 respectively in eclipse.ini file. You can increase it according to you or according to your system ram.
And then restart eclipse.

This solution is very efficient when the issue is persist after restarting the machine. – Shadyar May 28 '21 at 22:34

For me the issue was with the build path of the maven project. Try configuring the build path and include only what is actually required is what i learnt. My parent maven project had 10+ child modules. My eclipse would take 3-4 mins waiting for background process for every file save. I removed [parent module]/src from the build path and restarted eclipse and issue got fixed.

If the issue is persist after restarting the machine, probebly you have a loop of dependencies in your modules. I.e. there is a dependency deadlock between your modules, eg. in PUM file of module1, it needs module2 and in PUM file of module2, it needs module1.
To solve the problem, verify your PUM files in your relevant modules or sub projects.
