Question

我正在尝试将现有的多模块Ant项目迁移到Maven。我已经成功生成了相关的POM文件并添加了正确的依赖关系。但是对于特定的模块，构建始终因StackOverflowError而失败。我的项目结构是：

OALSCMProdDataSync
|
---Properties
|
---Utilities
|
---Model
|
---RESTClient
|
---RESTServices
|
---EARModule

在这种情况下，正确构建了Properties和Utilities jar，但是Model构建始终因以下错误而失败：

Exception in thread "main" java.lang.StackOverflowError
    at java.util.IdentityHashMap.hash(IdentityHashMap.java:294)
    at java.util.IdentityHashMap.get(IdentityHashMap.java:328)
    at org.eclipse.aether.util.graph.transformer.ConflictResolver$ConflictContext.isIncluded(ConflictResolver.java:1062)
    at org.eclipse.aether.util.graph.transformer.NearestVersionSelector$1.accept(NearestVersionSelector.java:145)
    at org.eclipse.aether.util.graph.visitor.PathRecordingDependencyVisitor.visitEnter(PathRecordingDependencyVisitor.java:93)
    at org.eclipse.aether.graph.DefaultDependencyNode.accept(DefaultDependencyNode.java:334)

注意：Model模块所需的依赖项已正确下载到我的.m2存储库中。

任何建议都值得赞赏。添加3个模块的POM文件。

Answer 1

解决了问题。 2个不同的远程存储库中的特定工件有相同的路径，该路径正遇到堆栈溢出错误。删除了其中一个并解决了问题。

已下载Maven依赖项，但构建失败，并出现StackOverflowError
