I have tried to make a project that connects to a DB and takes information and outputes them in a desktop application through grpc. But, when I compile it I get "Error:(20,18) java: cannot find symbol" in a target file( which is auto-generated by protoc. I can't understand the issue with this. I have tried to change the compiler of mvn, to change the version on protoc, to setup a different JDK, everything just gets worse that it already is.
My project can be viewed here : https://github.com/Diana-Ioana/grpc My db and error with the generated target files that crashes is : https://i.sstatic.net/7U1zB.jpg
I have no idea what to do now. Any help would be greate, thank you!
It looks like the "cannot find symbol" is referring to javax.annotation.Generated. In that case you can add a dependency on annotations-api:
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>annotations-api</artifactId>
<version>6.0.53</version>
<!-- Generated has @Retention(SOURCE), so not needed at runtime -->
<scope>provided</scope>
</dependency>
Originally this answer suggested javax.annotation-api, but that library is licensed CDDL so gRPC changed its recommendation.
<!-- The old suggestion. Uses CDDL-licensed library -->
<dependency>
<groupId>javax.annotation</groupId>
<artifactId>javax.annotation-api</artifactId>
<version>1.2</version>
</dependency>
