@Named

@Priority(15)
public class ToolchainPluginStrategy
extends AbstractUpgradeStrategy

Strategy for adding the maven-toolchains-plugin with the select-jdk-toolchain goal when the project's declared --source/--release level has been retired by a newer JDK (per JEP 182).

This strategy is independent of the JDK used to run mvnup: it acts purely on what the project declares. A project targeting --source 6 needs the toolchain plugin regardless of whether mvnup is invoked under JDK 11 or JDK 25.

This strategy detects the project's source level from:

1. maven.compiler.release property
2. maven.compiler.source property
3. Compiler plugin <configuration><release> or <source>

If the declared source level is retired (i.e. no longer accepted by the latest JDK) and the maven-toolchains-plugin is not already configured with the select-jdk-toolchain goal, this strategy adds it so that the plugin's built-in JDK discovery mechanism can find a compatible JDK at build time.
