The ide is "Updating Indices" of JDK, 3rd jars, .gradle/ folder etc again and again and again when openning the project. It takes too long time, and cannot be canclled. Making IDEA totally unusable, very very very annoying!
This happening in all versions of idea with gradle plugin.
This feature must be improved, some suggestions:
(1) do not index the same thing more than once
(2) let user to define the exclude-set of indexed folders
(3) do not index unused stuffs; try to identify which are unused
(4) do not block user operations when it's indexing
