Reproduisez le problème en clonant OpenGrok et en l’ouvrant dans VS Code. Commencez par opengrok-indexer/src/main/java/org/opengrok/indexer/analysis/ada/AdaAnalyzer.java et les sources générées sous opengrok-indexer/target/generated-sources/jflex/org/opengrok/indexer/analysis. C’est terminé lorsque les types Java générés sont résolus et que le projet ne signale plus ces diagnostics.
