    if match is found, the toolchain instance is made available to other Maven plugins.</p>
    <p>With {@code jdk} toolchain, for example, instead of being stuck with the JDK used to run Maven, all plugins can use
    the same other JDK instance without hardcoding absolute paths into the {@code pom.xml}
    and without configuring every plugin that require path to JDK tools.</p>
