mvn 依赖项：树并不真正显示所有依赖项

java maven tree

我遇到了一个问题，编译一个包含许多依赖项的jar，特别是重叠版本（我们需要1.11，一些依赖项正在拉入1.9）。我们运行了，但我们在任何输出中都没有看到有问题的辅助版本。在进一步的检查中，是当时正在拉进来的。为什么没有向我们展示这种向下钻取级别：snakeyamlmvn dependency:treejruby-completesnakeyamlmvn dependency:tree

为什么 jruby-complete 的依赖项没有列在树中？是否只有一定深度的 gfo？这里的规则是什么？如果只是向我们展示它的依赖关系，我们可以节省几个小时的复杂调试。mvn dependency:treemvn dependency:treesnakeyaml

答案 1

我相信这个论坛主题会回答你的问题。依赖关系树 mojo 会修剪较低级别的依赖关系（如果依赖关系已存在于树中的较高位置）。这意味着 jruby-complete 的所有依赖项（如果有的话）都列在树中较浅的深度。可以使用详细标志（）来显示省略的依赖项。-Dverbose
