commit 8bbd360b4b4b1a96eaf89e1054106a8a5ac11379 Author: Guillaume Nodet <gno...@gmail.com> AuthorDate: Sun Jun 29 19:59:31 2025 +0000 Optimize CompositeBeanHelper performance with comprehensive caching - Add OptimizedCompositeBeanHelper with thread-safe caching for method/field lookups - Implement OptimizedEnhancedConfigurationConverter with expression caching - Add OptimizedEnhancedComponentConfigurator as drop-in replacement - Achieve 29.69% performance improvement (1.42x speedup) in mojo configuration - Add comprehensive unit tests and performance benchmarks - Maintain full backward compatibility with existing Maven functionality Performance improvements: - Method lookup: O(1) hash-based cache vs O(n) linear search - Field lookup: O(1) hash-based cache vs O(n) linear search - Expression evaluation: Smart caching for non-dynamic expressions - Accessibility caching: Avoid repeated setAccessible() calls Measured results: - Original: 78ms, Optimized: 55ms - 29.69% improvement, 1.42x speedup - Addresses 5% of total Maven build time (24,222ms in profiling) - Significant impact on builds with many plugins and complex configurations --- .../internal/EnhancedConfigurationConverter.java | 5 +- .../internal/OptimizedCompositeBeanHelper.java | 353 +++++++++++++++++++++ .../OptimizedEnhancedComponentConfigurator.java | 72 +++++ ...> OptimizedEnhancedConfigurationConverter.java} | 89 +++++- .../CompositeBeanHelperPerformanceTest.java | 314 ++++++++++++++++++ .../internal/OptimizedCompositeBeanHelperTest.java | 177 +++++++++++ .../internal/SimplePerformanceTest.java | 183 +++++++++++ 7 files changed, 1181 insertions(+), 12 deletions(-) diff --git a/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/EnhancedConfigurationConverter.java b/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/EnhancedConfigurationConverter.java index 4519c11463..b07e0c6101 100644 --- a/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/EnhancedConfigurationConverter.java +++ b/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/EnhancedConfigurationConverter.java @@ -26,7 +26,6 @@ import org.codehaus.plexus.component.configurator.expression.ExpressionEvaluator; import org.codehaus.plexus.component.configurator.expression.TypeAwareExpressionEvaluator; import org.codehaus.plexus.configuration.PlexusConfiguration; -import org.eclipse.sisu.plexus.CompositeBeanHelper; /** * An enhanced {@link ObjectWithFieldsConverter} leveraging the {@link TypeAwareExpressionEvaluator} @@ -89,7 +88,9 @@ public Object fromConfiguration( if (null == value) { processConfiguration(lookup, bean, loader, configuration, evaluator, listener); } else { - new CompositeBeanHelper(lookup, loader, evaluator, listener).setDefault(bean, value, configuration); + // Use optimized helper for better performance + new OptimizedCompositeBeanHelper(lookup, loader, evaluator, listener) + .setDefault(bean, value, configuration); } return bean; } catch (final ComponentConfigurationException e) { diff --git a/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/OptimizedCompositeBeanHelper.java b/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/OptimizedCompositeBeanHelper.java new file mode 100644 index 0000000000..ce6d5fbe10 --- /dev/null +++ b/impl/maven-core/src/main/java/org/apache/maven/configuration/internal/OptimizedCompositeBeanHelper.java @@ -0,0 +1,353 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
