Talend - Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import routines cannot be resolved

Question

While working on Talend Integration Open Studio v7.3.1 & v7.2.1, I am facing below error:

    Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
        The import routines cannot be resolved
        The import routines cannot be resolved
        The import routines cannot be resolved
        The import routines cannot be resolved
        TalendJob cannot be resolved to a type
        RunStat cannot be resolved to a type
        RunStat cannot be resolved to a type
        routines cannot be resolved to a type
        LogCatcherUtils cannot be resolved to a type
        LogCatcherUtils cannot be resolved to a type
        TDieException cannot be resolved to a type
...

Even though there is no compile error in main job or sub jobs, the main job gives the above error sporadically. In order to overcome this error, I have to restart my Talend Studio and then the error goes away. But restarting studio is a costly affair because it checks for components in background and hangs the open studio for good 10-15 mins. And there is no setting in "open studio" to disable the components check.

Is there any better way to fix this "Unresolved compilation problems" issue?

This Talend Community post worked for me: https://community.talend.com/s/feed/0D53p00007vCkCBCA0?language=en_US "In the Talend Open Studio, Go to menu File -> Edit Project properties In project Settings go to: Build -> Maven -> Default -> Project

And click OK" (or apply and close)
