"Remote System Explorer Operation" causing freeze for couple of seconds

Viewed 84352

I observe "Remote System Explorer Operation" in Progress view of Eclipse after each save of Java file (so it might be related to compiling?). It makes the Eclipse unusable for 1 to 10 seconds. In some projects (of about the same size) it's quicker, in some it's slower.

I have no idea which plugin might be the cause for it. I have Build id: 20090920-1017. I have quite a few plugins installed.

I have tried turning all the remote systems to enabled=false under Preferences | Remote Systems (whatever it means). I didn't help.

Any idea how to solve it?

EDIT:

  1. It doesn't happen when Project | Build automatically is turned off. So it's some part of the building process.

For me at this time for Spring Tool Suite 3.9.4. Release disabling remote system via preferences menu fixed the issue. Here is the reference that helped me. but after a while, the problem is there again!

Switched to eclipse photon one week, didn't see the annoying "remote system...." any longer.

I was also experienced multiple remote system explorer operations while compiling a C++ project in eclipse (I'm using Nsight bu nvidia - eclipse based platform). After i did all the suggested solutions here, I still had the problem.

BUT- when i changed the -Wall option to -w option for the gcc compiler the problem disappeared.

GO TO - Project Properties -> Build-> Settings -> Tool settings tab-> gcc compiler -> warnings -> uncheck -Wall and check -w

The same goes for G++ Compiler.

I also experienced "Remote System Explorer Operation" tasks running on resource save.

When using AspectJ Around method In my case, it was caused by Aspectj around method Spring AOP markers creation.

Delete the AspectJ Markers from the Eclipse Markers console system hang issue will be solved automatically.
