meetingfere.blogg.se - Compiling java with dependencies

"nearest definition" means that the version used will be the closest one to your project in the tree of dependencies.

Note that if two dependency versions are at the same depth in the dependency tree, the first declaration wins. You can always guarantee a version by declaring it explicitly in your project's POM. That is, it uses the version of the closest dependency to your project in the tree of dependencies.

Dependency mediation - this determines what version of an artifact will be chosen when multiple versions are encountered as dependencies.

For this reason, there are additional features that limit which dependencies are included:

With transitive dependencies, the graph of included libraries can quickly grow quite large. A problem arises only if a cyclic dependency is discovered. There is no limit to the number of levels that dependencies can be gathered from. In general, all dependencies of those projects are used in your project, as are any that the project inherits from its parents, or from its dependencies, and so on. This feature is facilitated by reading the project files of your dependencies from the remote repositories specified. Maven avoids the need to discover and specify the libraries that your own dependencies require by including transitive dependencies automatically.

Maven helps a great deal in defining, creating, and maintaining reproducible builds with well-defined classpaths and library versions. Managing dependencies for multi-module projects and applications that consist of hundreds of modules is possible. Managing dependencies for a single project is easy. Dependency management is a core feature of Maven.
