I use gRPC to generate java code '@javax.annotation.Generated' and it reports 'Error:(20,18) java: cannot find symbol'. How to solve it？

Question

I use gRPC to generate code '@javax.annotation.Generated' like below picture.

Then I use maven to build the project, and it reports 'Error:(20,18) java: cannot find symbol' like below picture.

How to solve it？

Answer 1

you can add javax.annotation-api dependencies to you maven pom.xml to resolve the annotation.

<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.2</version>
</dependency>

Answer 2

In my case this was caused by building the project on a system with too new version of Java accidentally installed (19 instead of 8). Changing Java version from 19 to 8 in File -> Project Structure fixed the issue for me.
