IntelliJ Idea doesn't recognize Lombok's annotations [duplicate]

问题

This question already has answers here:

Can't compile project when I'm using Lombok under IntelliJ IDEA (26 answers)

Closed last year.

I'm trying to introduce Lombok annotations into a Maven Java project in IntelliJ IDEA and followed the steps here and here.

@Data annotation (for one) is not being recognized:

Here's the relevant Maven stanza:

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.16.18</version>
    </dependency>
</dependencies>

I'm on Idea 2017.3.2 CE.

I tried the solution mentioned here, it doesn't work:

Doing File | Invalidate Caches & Restart didn't help.

What am I missing here?

回答1:

What helped was going into File | Project structure and adding a library from Maven (via search for org.projectlombok there):

That downloaded the missing jar into the local repo which I assumed should have been done by the Lombok plugin.

Seems to be yet another IntelliJ Idea bug or at least a shortcoming not clearly mentioned in either Lombok or IntelliJ plugin documentation. I've opened an issue here, perhaps this will save some struggle to other developers in the meantime.
