Lombok false positive: MissingOverride for "@EqualsAndHashCode(callSuper = true)" when extending base class

[ksilz]

Description of the problem / feature request:

I'm compiling my Java 11 Spring Boot program with Error Prone and get a false positive on MissingOverride in a class that has the Lombok annotation @EqualsAndHashCode(callSuper = true) and extends another class.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

I reproduced the error in a test case repo.

• Make sure that you have Java 11 installed.
• Clone https://github.com/ksilz/check-error-prone
• Run gradlew.bat (Windows) or ./gradlew (Mac, Linux).
• The application runs fine.
• Edit build.gradle:
  • Comment out the line with excludedPaths = ".*/issues/.*", currently line 103. This would include all files for Error Prone.
  • Uncomment the excludedPaths line for this issue Lombok false positive: MissingOverride for "@EqualsAndHashCode(callSuper = true)" when extending base class #1481, which is currently line 123.
  • Save.
• Run gradlew.bat (Windows) or ./gradlew (Mac, Linux) again.
• You get the warning below. The error is in missingoverride/IssueShowCase.java

[...]/src/main/java/com/betterprojectsfaster/test/errorprone/lombokErrorProne/issues/missingoverride/IssueShowCase.java:8: warning: [MissingOverride] canEqual overrides method in Base; expected @Override
@EqualsAndHashCode(callSuper = true)
^
    (see https://errorprone.info/bugpattern/MissingOverride)
    Did you mean '@Override @EqualsAndHashCode(callSuper = true)'?

What version of Error Prone are you using?

Here's my my environment:

• macOS Catalina 10.15.2
• Gradle 5.6.4
• AdoptOpenJDK Eclipse OpenJ9 11.0.5
• Lombok 1.18.10
• Error Prone Gradle plug-in 1.1.1
• Error Prone 2.3.4

Have you found anything relevant by searching the web?

Didn't find anything relevant in the mailing list. Here are related Lombox issues:

• #1479: Lombok - MultiVariableDeclaration: IllegalArgumentException "Start [449] should not be after end [-1]" (Preconditions.java:300)
• #1430:
  IllegalArgumentException from AlmostJavadoc pattern on project using lombok

Please re-open this or file a new bug if you're still seeing issues with Lombok and Error Prone 2.13.0 when -XepDisableWarningsInGeneratedCode is enabled.
