Brief examples on how to use the toolchains plugin.
See the following links for information about including and configuring plugins in your project:
Toolchain is a preconfigured object that maven plugins can ask for tool location and other information. The toolchains-plugin can read the persisted toolchains on the user's computer and match it against the toolchain requirements of the project (as configured in pom.xml) If match is found, the toolchain instance is made available to other maven plugins. That way all plugins can use the same JDK instance for example without hardcoding absolute paths into the pom.xml and without configuring all plugins that require path to JDK tools.
This goal are meant to be bound to a lifecycle phase and configured in your pom.xml. In order to function properly it shall be the first phase in the lifecycle, eg. the "validate" phase.
The available standard toolchains are described here.
