Refactor AddonManager to support addon version conflicts -------------------------------------------------------- Key: FORGE-988 URL: https://issues.jboss.org/browse/FORGE-988 Project: Forge Issue Type: Enhancement Components: Addon Manager Affects Versions: 2.0.0.Alpha6 Reporter: George Gastaldi Assignee: George Gastaldi Priority: Critical Fix For: 2.0.0.Alpha10 Given that Addons A(1.0), B (1.0), C(1.0) are installed in an AddonRepository, and C(1.0) depends on B(1.0), when an addon D(1.0) to be installed requires B(1.1), there should be a way to warn against incompatibilities and let the user decide what to do. Same when D(1.0) depends on B(2.0) Basically an addon version is composed of Major.Minor.Micro In relation to the installed addon version and the requested addon version the following rules should be followed: - When Major version is different, the addons are assumed be completely incompatible (even if in practice that is not true). Fail installation - When Minor version is different, compatibility may be assured only if the requested version is less or equal to the required version. Prompt for installation of necessary version. - When Micro version is different, the addon is totally compatible, thus no compatibility check is required. No problem to install
