從Maven項目下載所有插件依賴項

我試圖在實際使用它們之前從Maven項目下載所有插件依賴項。從Maven項目下載所有插件依賴項

我試着運行：

mvn dependency:resolve-plugins

而這種成功下載它的插件及其依賴的一部分。例如，對於Exec插件我得到：

...

但是，當你真正使用的插件，例如：

mvn exec:exec

事實證明它的依賴尚未完全下載。

這是出乎意料的，因爲according to the documentation的excludeTransitive屬性爲默認值（和明確設置它並不能幫助）假。從我所看到的情況來看，它只是從定義的插件中下載一層傳遞依賴關係。

在實際需要它們之前，是否有辦法讓依賴插件下載所有傳遞插件依賴項，而不是隻有第一級插件依賴項？
