Question

执行mvn dependency:tree后，我得到以下输出：

我的问题是javax.transaction-api:jar:1.2-b03:compile被排除在外的原因？我没有明确指定任何排除。怎么了？

Answer 1

也许您需要更新您的maven项目以重新加载依赖项。

Answer 2

输出未显示依赖项的任何排除。实际上，如果依赖项被排除，它将不会在依赖关系树中显示。通过查看树，依赖关系显示在最后一行：

[INFO] \- javax.transaction:javax.transaction-api:jar:1.2-b03:compile

为什么排除了maven依赖？
