A rule engine is also a fundamental building block to create an expert system which, in artificial intelligence, is a computer system that emulates the decision-making ability of a human expert.\n\nBe sure to check out the Apache KIE project [website](https://kie.apache.org/docs/components/drools/) and [documentation](https://kie.apache.org/docs/documentation/)!\n\n\nTest execution tip\n==================\n\nSome test are meant to be executed on machine with _en_US_ locale.\nA specific profile is provided to execute them on machines with different locale, namely `test-en`.\nThere are two ways to activate such profile during maven build:\n1. `-Ptest-en` (profile-id based)\n2. `-DTestEn` (property based)\n\nThe following two commands will execute tests on machine with locale different than _en_US_:\n\n1. `make test -Ptest-en`\n2. `make test -DTestEn`\n\nTroubleshooting\n================\nIf the build fails with `UnmappableCharacterException`, set `-Dfile.encoding=UTF-8` for `MAVEN_OPTS` (not as an argument of `mvn` command). Then run `mvn`.\n\nexample for Windows:\n```shell\nset MAVEN_OPTS=-Dfile.encoding=UTF-8\nmvn clean install\n```\n\nDocumenting tips\n================\n\nUML diagrams have been used for architectural and design documentation. Those diagrams are in \".puml\" format and have been created using the [PlantUML](https://plantuml.com/https://plantuml.com/) tool.\nPlugins exists to use it in different IDE:\n* [IDEA](https://plugins.jetbrains.com/plugin/7017-plantuml-integration)\n* [Eclipse](https://marketplace.eclipse.org/content/plantuml-plugin)\n* [VisualStudio](https://marketplace.visualstudio.com/items?itemName=jebbs.plantuml)\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Fincubator-kie-drools","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fapache%2Fincubator-kie-drools","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Fincubator-kie-drools/lists"}
