--------------------------------------------

             Summary: Gradle build fails due to deprecated metadata APIs
                 Key: CALCITE-4798
                 URL: https://issues.apache.org/jira/browse/CALCITE-4798
             Project: Calcite
          Issue Type: Bug
          Components: build
            Reporter: Stamatis Zampetakis
            Assignee: James Starr
             Fix For: 1.28.0


Running {{./gradlew build}} locally fails since {{CachingRelMetadataProvider}} was deprecated in [b51a2e14343df089ee0b6c3e8a20c00c51186421|https://github.com/apache/calcite/commit/b51a2e14343df089ee0b6c3e8a20c00c51186421] but is still used in {{PlannerImpl}}.

Although locally the build fails it seems that in CI we are not using the {{-Werror}} flag so the error is hidden.
