commit fbd98ac007872d6b1d6234492cb76e4a7b62b1fa Author: Guillaume Nodet <[email protected]> AuthorDate: Tue Oct 7 09:05:31 2025 +0200 Fix StackOverflowError in parent resolution with relativePath cycles This commit fixes the StackOverflowError that occurs when Maven encounters circular parent references using relativePath. The issue was that the cycle detection logic for file paths (parentSourceChain) was not being properly propagated through all recursive calls in the parent resolution chain. The problem manifested when a parent POM references itself or creates a circular dependency chain through relativePath, causing infinite recursion in the parent resolution process: readParentLocally → resolveParent → readParent → doReadAsParentModel → readAsParentModel → readParentLocally (infinite loop) Key changes in DefaultModelBuilder: - Added cycle detection for file paths in readParentLocally() method - Added method overloads to pass parentSourceChain through the call chain: * readParent() now accepts both parentChain and parentSourceChain * resolveParent() now accepts both parentChain and parentSourceChain * resolveAndReadParentExternally() now accepts both chains - Modified doReadAsParentModel() to pass parentSourceChain to readParent() - Updated derive() method to create new parentChain for each session while sharing parentSourceChain across all sessions for global cycle detection - Fixed all recursive calls to properly propagate parentSourceChain The fix prevents infinite recursion by detecting when the same file path is encountered multiple times in the parent resolution chain and throwing a meaningful ModelBuilderException instead of allowing a StackOverflowError. Added comprehensive tests: - ParentCycleDetectionTest: Unit test that reproduces and validates the fix - MavenITmng11009StackOverflowParentResolutionTest: Integration test with test resources that demonstrate the circular parent scenario Fixes #11009 --- .../maven/impl/model/DefaultModelBuilder.java | 215 +++++++++++++++------ .../maven/impl/model/ParentCycleDetectionTest.java | 203 +++++++++++++++++++ ...Tmng11009StackOverflowParentResolutionTest.java | 71 +++++++ .../parent/pom.xml | 36 ++++ .../pom.xml | 36 ++++ 5 files changed, 503 insertions(+), 58 deletions(-) diff --git a/impl/maven-impl/src/main/java/org/apache/maven/impl/model/DefaultModelBuilder.java b/impl/maven-impl/src/main/java/org/apache/maven/impl/model/DefaultModelBuilder.java index 9e2a776d7a..b12090412b 100644 --- a/impl/maven-impl/src/main/java/org/apache/maven/impl/model/DefaultModelBuilder.java +++ b/impl/maven-impl/src/main/java/org/apache/maven/impl/model/DefaultModelBuilder.java @@ -273,6 +273,10 @@ protected class ModelBuilderSessionState implements ModelProblemCollector { List<RemoteRepository> externalRepositories;
