Incorrect warning about file declaring wrong package ---------------------------------------------------- Key: DROOLS-5434 URL: https://issues.redhat.com/browse/DROOLS-5434 Project: Drools Issue Type: Bug Components: core engine Reporter: Magnus Larsson Assignee: Mario Fusco Priority: Major Attachments: image-2020-09-03-09-20-10-089.png I am running Drools in a Spring-Boot jar and get the following warning statement _File 'BOOT-INF/classes/com/example/test/TEST.drl' is in folder 'BOOT-INF/classes/com/example/test' but declares package 'com.example.test'. It is advised to have a correspondance between package and folder names_. The package name in the drl file is correct, the problem is just that _BOOT-INF.classes._ isn't considered when evaluating if printing the warning or not. I have tracked it down to *KieBuilderImpl.java*, method *isFileInKieBase*. The last 2 lines in that method calls: {code:java} // packageNameForFile prints warning if package in .drl file is not same as flatted directory structure // Does not care about SUPPORTED_RESOURCES_ROOTS, thus prints the warning String pkgNameForFile = packageNameForFile( fileName, folderNameForFile, !useFolders, file ); // Does care about SUPPORTED_RESOURCES_ROOTS, so the drl file is loaded return isPackageInKieBase( kieBase, pkgNameForFile ); {code} As it is implemented right now, the warning might either be a false-positive (and still get loaded), or the package is wrong (and the file is not loaded). Voting to include the SUPPORTED_RESOURCES_ROOTS as valid prefixes when checking if the warning should be printed.
