我是Maven的新手，并在Windows 64位机器中安装了3.5.0。我已经按照 https://avro.apache.org/docs/1.8.2/gettingstartedjava.html 中的规定在pom.xml中添加了 Avro 依赖项。我面临构建失败并在从命令行执行mvn clean compile时遇到ArrayIndexOutOfBoundsException：

简而言之：下载pom时，文件已损坏。由于某种原因，在结束标记之后添加了额外的内容，使其成为无效的 xml 文件。Maven 3.3.9 及之前忽略了之后的所有数据，3.5.0 更加严格。有 2 个简单的解决方案：删除本地存储库或使用 maven 3.3.9
哪里还在寻找这个问题的原因。它可能已经存在了很长时间，但这从来都不是问题。
您可以检查 avro 的 pom，因为该 pom 导致了问题或其依赖项之一。
