Add the mvnlog tool for viewing and analyzing build-report JSON files. Includes BuildReportRenderer for human-readable output, SimpleJsonReader for dependency-free JSON parsing, shell scripts (mvnlog/mvnlog.cmd), and --log routing in mvn/mvn.cmd. Also adds integration tests for build report generation, console modes, and the mvnlog viewer, plus --console=verbose flags for ITs that depend on verbose output. Part 5 of the #12572 split (depends on warning mode PR #12698). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…ollector Route structured validation problems from 4 pathways (settings, toolchains, model validation, graph building) into DefaultDiagnosticCollector so they appear in the build report with full key/suggestion/documentationUrl metadata instead of being re-logged as plain text. Pathways: - LookupInvoker: settings validation problems - MavenInvoker: toolchains validation problems - DefaultProjectsSelector: model validation problems (ModelProblem → BuilderProblem) - DefaultMaven: graph building problems (ModelProblem → BuilderProblem) Also adds EXCLUDED_LOGGERS in BuildReportCollector to prevent double-counting when the same problems are both piped structurally and logged via SLF4J. Migrates all test files from DefaultBuilderProblem constructor to BuilderProblem.builder() API. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Change the PluginValidationManager interface from String-based to BuilderProblem-based, enabling structured problem reporting with keys, severity, and suggestions throughout the plugin validation pipeline. - Change 3 abstract report methods from String issue to BuilderProblem - Add deprecated String-based default methods for backward compat - Update all 9 call sites (7 validators + 1 plugin manager) to create BuilderProblem with structured key, severity, and suggestion - Inject DefaultDiagnosticCollector into DefaultPluginValidationManager to pipe problems into the diagnostic pipeline - Add japicmp exclusion for the intentional API break - Add DefaultPluginValidationManager to EXCLUDED_LOGGERS in BuildReportCollector to prevent double-counting Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Follow-up to the build report / warning mode chain. This PR implements the structured
BuilderProblempipeline for the 4 pathways identified in the foundation work, plus a full migration of thePluginValidationManagerinterface.Commit 1: Pipe structured BuilderProblems into DiagnosticCollector (Pathways 1–4)
Pathway 2 — Plugin parameter validation (
AbstractMavenPluginParametersValidator): 3 validators now createBuilderProblemwith structured key, severity, and suggestion, and pipe throughPluginValidationManager→DiagnosticCollector.Pathway 3 — Plugin dependency validation (
AbstractMavenPluginDependenciesValidator): 4 validators now createBuilderProblemwith structured key and pipe throughPluginValidationManager→DiagnosticCollector.Pathway 4 — Plugin manager Contextualizable check (
DefaultMavenPluginManager): createsBuilderProblemwith keyplugin-validation:contextualizableand pipes throughPluginValidationManager→DiagnosticCollector.Commit 2: Migrate PluginValidationManager to native BuilderProblem API
