| Jun 6, 2017 at 12:22 | comment | added | Jilles van Gurp | I just ran into this as well with 2017.1.3 My gradle project is definitely set to JDK 8 and it was even suggesting OptionalDouble and other classes from the same package. But it kept autocorrecting to the guava version of Optional and removing any manually added import for java.util.Optional. I fixed it by exiting, gradle cleaning, killing the IDE, editing the file manually outside of intellij, and then restarting intellij. The problem finally went away. It looks to me that the autocomplete data can get in a weird state sometimes. | |

Recently it became even weirder in that even more classes could not be found but the project compiles, runs and debugs from within IDEA just fine but most code completion and lots of tooling doesn't work anymore :( It's a Maven-based project btw, I tried deleting and re-importing it but that didn't help. | |

| Dec 18, 2014 at 19:19 | comment | added | mkobit | Are you sure the Project SDK that is selected points to JDK 8, and that your modules Language level is also using the correct JDK? | |

Is your IntellJ version fairly recent? At least 13.1.x?
