Maven Toolchain Model

 This is the model for Maven toolchain in <<<org.apache.maven.toolchain>>> package,
 delegating content to {{{../api/maven-api-toolchain/index.html}Maven 4 API immutable toolchain}}. All the effective model
 building logic from multiple toolchains files is done in {{{../maven-toolchain-builder/}Maven Toolchain Builder}}.

 The following are generated from this model:

import org.apache.maven.artifact.resolver.ArtifactResolutionException;
import org.apache.maven.artifact.resolver.ArtifactResolutionRequest;
import org.apache.maven.artifact.resolver.ArtifactResolutionResult;
import org.apache.maven.artifact.resolver.MultipleArtifactsNotFoundException;
