-0400 Subject: [PATCH 02/18] Add integration tests and fix default reconciliation merging - Created integration tests for three scenarios: * No executionControl configuration (defaults apply automatically) * executionControl with other plugin (defaults still apply to unconfigured plugins) * Explicit plugin config (overrides defaults for that plugin only) - Implemented parameter export/categorization system: * Created plugin-parameters.xsd schema * Added maven-compiler-plugin.xml (57 parameters) * Added maven-install-plugin.xml (22 parameters) * Parameter validation with ERROR/WARN logging * Version-specific parameter support with best-match selection - Implemented XML-based default reconciliation: * Created default-reconciliation.xsd schema * Created defaults.xml with maven-compiler-plugin and maven-install-plugin * Implemented DefaultReconciliationLoader to replace hardcoded defaults - Updated documentation: * Clarified that defaults are built-in (not user-customizable) * Added example showing how to override defaults via .mvn/maven-build-cache-config.xml * Documented parameter validation and version-specific definitions ---

Changes: - Remove defaults.xml (no longer needed - all plugins have XML definitions) - Remove DefaultReconciliationLoader class (replaced by auto-generation) - Add generateReconciliationFromParameters() method to CacheConfigImpl that automatically creates reconciliation configs by reading functional parameters from plugin parameter definitions - Auto-generation runs as final fallback after explicit config check Benefits: - Single source of truth (plugin-parameters/*.xml defines everything) - More comprehensive tracking (all functional params, not just 3) - Easier maintenance (no need to keep defaults.xml in sync) - Future-proof (new plugins with XML definitions get auto-tracking) For maven-compiler-plugin: - Before: Tracked 3 params (source, target, release) - After: Tracks ALL 15 functional params (source, target, release, encoding, debug, debuglevel, optimize, compilerArgs, etc.) All existing tests pass, including DefaultReconciliationTest which validates the auto-generation works correctly.

Root Cause: - Auto-generated reconciliation configs track functional parameters - When restoring a cache created with different tracked properties, validation rejected the cache if ANY properties were missing - This prevented reconciliation checks from running and detecting actual parameter changes Changes: 1. CacheControllerImpl.java (isCachedSegmentPropertiesPresent): - Allow cache restore even when some tracked properties are missing - Changed from failing fast to logging and proceeding - Reconciliation check handles missing properties with defaults - Provides backward compatibility when adding new tracked parameters 2. BuildCacheMojosExecutionStrategy.java (isParamsMatched): - Add exception handling for missing mojo properties - Catch all exceptions, not just IllegalAccessException - Treat missing properties as "null" instead of crashing - Remove 'final' modifier from currentValue for exception handling 3. CacheConfigImpl.java (generateReconciliationFromParameters): - Add debug logging for auto-generation process - Changed logging from INFO to DEBUG level - Helps troubleshoot reconciliation behavior Test Results: - All 83 unit tests pass - All 25 integration tests pass - Previously failing tests now pass: * DefaultReconciliationTest (2 tests) * DefaultReconciliationWithOtherPluginTest * MandatoryCleanTest (2 tests) * IncrementalRestoreTest * ForkedExecutionCoreExtensionTest * Issue67Test * Issue99Test Addresses review feedback: - Implements ERROR→WARN logging change per AlexanderAshitkin comment - Uses ConcurrentHashMap for thread safety per review comment --- .../BuildCacheMojosExecutionStrategy.java | 20 ++++++++++++++++++- .../maven/buildcache/CacheControllerImpl.java | 12 +++++++---- .../maven/buildcache/xml/CacheConfigImpl.java | 18 +++++++++++++++++ 3 files changed, 45 insertions(+), 5 deletions(-) diff --git a/src/main/java/org/apache/maven/buildcache/BuildCacheMojosExecutionStrategy.java b/src/main/java/org/apache/maven/buildcache/BuildCacheMojosExecutionStrategy.java index 63efca75..6f70c792 100644 --- a/src/main/java/org/apache/maven/buildcache/BuildCacheMojosExecutionStrategy.java +++ b/src/main/java/org/apache/maven/buildcache/BuildCacheMojosExecutionStrategy.java @@ -503,6 +503,14 @@ boolean isParamsMatched( CompletedExecution completedExecution) { List tracked = cacheConfig.getTrackedProperties(mojoExecution); + if (mojoExecution.getPlugin() != null) { + LOGGER.debug( + "Checking parameter match for {}:{} - tracking {} properties", + mojoExecution.getPlugin().getArtifactId(), + mojoExecution.getGoal(), + tracked.size()); + } + for (TrackedProperty trackedProperty : tracked) { final String propertyName = trackedProperty.getPropertyName(); @@ -511,7 +519,7 @@ boolean isParamsMatched( expectedValue = trackedProperty.getDefaultValue() != null ? trackedProperty.getDefaultValue() : "null"; } - final String currentValue; + String currentValue; try { Object value; if (trackedProperty.getExpression() != null) { @@ -524,8 +532,18 @@ boolean isParamsMatched( } catch (IllegalAccessException e) { LOGGER.error("Cannot extract plugin property {} from mojo {}", propertyName, mojo, e); return false; + } catch (Exception e) { + // Catch all exceptions including NullPointerException when property doesn't exist in mojo + LOGGER.warn( + "Property '{}' not found in mojo {} - treating as null", + propertyName, + mojo.getClass().getSimpleName()); + currentValue = "null"; } + LOGGER.debug( + "Checking property '{}': expected='{}', actual='{}'", propertyName, expectedValue, currentValue); + if (!Strings.CS.equals(currentValue, expectedValue)) { if (!Strings.CS.equals(currentValue, trackedProperty.getSkipValue())) { LOGGER.info( diff --git a/src/main/java/org/apache/maven/buildcache/CacheControllerImpl.java b/src/main/java/org/apache/maven/buildcache/CacheControllerImpl.java index 746034c8..dfe2009b 100644 --- a/src/main/java/org/apache/maven/buildcache/CacheControllerImpl.java +++ b/src/main/java/org/apache/maven/buildcache/CacheControllerImpl.java @@ -1049,14 +1049,18 @@ private boolean isCachedSegmentPropertiesPresent( return false; } + // Allow cache restore even if some tracked properties are missing from the cached build. + // The reconciliation check will detect mismatches and trigger rebuild if needed. + // This provides backward compatibility when new properties are added to tracking. if (!DtoUtils.containsAllProperties(cachedExecution, trackedProperties)) { - LOGGER.warn( - "Cached build record doesn't contain all tracked properties.
