Hi Mario, During the release of Alpha7 I had to change a couple of poms by hand as dependencies' version numbers were hard-coded: https://github.com/droolsjbpm/drools/commit/faa3bb0ff51d469ad37601d023234... Ideally the dependency version should be a variable in the parent pom. For example the dependency of "org.drools.default-kiesession" should probably be "${drools.version}":- <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>drools-examples-api</artifactId> <groupId>org.drools</groupId> <version>6.0.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>default-kiesession-from-file</artifactId> <name>Drools API examples - Default KieSession From File</name> <dependencies> <dependency> <groupId>org.drools</groupId> <artifactId>drools-compiler</artifactId> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>default-kiesession</artifactId> *<version>6.0.0-SNAPSHOT</version>* </dependency> </dependencies> </project> With kind regards, Mike
