From ecd577b363e0b7dd45cd7ab05f1c46f61c6a8bf8 Mon Sep 17 00:00:00 2001 From: Tamas Cservenak Date: Mon, 12 Aug 2024 13:51:26 +0200 Subject: [PATCH] [MNG-8177] Add contextual info for model warnings (#1633) As they really can come from anywhere. In case of this issue even from some eliminated POM that was read while collecting dirty tree, and was later eliminated. So confusing for users. --- https://issues.apache.org/jira/browse/MNG-8177 --- .../DefaultArtifactDescriptorReader.java | 31 ++++++-- .../internal/RequestTraceHelper.java | 77 +++++++++++++++++++ 2 files changed, 100 insertions(+), 8 deletions(-) create mode 100644 maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/RequestTraceHelper.java diff --git a/maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/DefaultArtifactDescriptorReader.java b/maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/DefaultArtifactDescriptorReader.java index 9054f89afd..bfea91cb6c 100644 --- a/maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/DefaultArtifactDescriptorReader.java +++ b/maven-resolver-provider/src/main/java/org/apache/maven/repository/internal/DefaultArtifactDescriptorReader.java @@ -42,6 +42,7 @@ import org.apache.maven.model.building.ModelBuildingResult; import org.apache.maven.model.building.ModelProblem; import org.apache.maven.model.building.ModelProblemUtils; import org.apache.maven.model.resolution.UnresolvableModelException; +import org.codehaus.plexus.util.StringUtils; import org.eclipse.aether.RepositoryEvent; import org.eclipse.aether.RepositoryEvent.EventType; import org.eclipse.aether.RepositoryException; @@ -195,6 +196,7 @@ public class DefaultArtifactDescriptorReader implements ArtifactDescriptorReader return result; } + @SuppressWarnings("MethodLength") private Model loadPom( RepositorySystemSession session, ArtifactDescriptorRequest request, ArtifactDescriptorResult result) throws ArtifactDescriptorException { @@ -293,16 +295,29 @@ public class DefaultArtifactDescriptorReader implements ArtifactDescriptorReader // that may lead to unexpected build failure, log them if (!modelResult.getProblems().isEmpty()) { List problems = modelResult.getProblems(); - logger.warn( - "{} {} encountered while building the effective model for {}", - problems.size(), - (problems.size() == 1) ?
