java - Maven 带来 "test"传递依赖为 "compile"

Question

当我为我的项目运行“mvn dependency:tree”时，它显示如下:

[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ xxxxx ---

正如您在标记行中看到的，xml-apis 具有“编译”范围，因此它被打包到 .war 文件中。为什么会发生？

更有趣的是，它仅在使用 Java5 时发生，对于 Java6，依赖项显示为“测试”。

Maven 版本:3.0.4

Answer 1

研究以下 Maven 命令的输出。

mvn -X dependency:tree -Dverbose

这应该告诉您为什么 Maven 将范围从测试升级到编译。
