如何獲得依賴管理和傳遞依賴之間「衝突」的Maven依賴關係收斂報告？

Question

我搜索一種方式來獲得一種依賴關係收斂報告，該報告列出了在dependency-management中定義的依賴關係，但被不同版本的傳遞依賴關係引用。

我知道maven-project-info-reports-plugin:dependency-convergence，但這個名單只是在dependency定義之間的依賴關係（和傳遞依賴）的衝突，但只要我定義了在dependency-management依賴，它就會沒有在報告中列出。

我只想報告，如果發生這樣的「衝突」，我不想讓構建失敗。

---

背景：

我有一個Maven的多模塊項目：

• 以前我沒有用過depencency-managent，但我用屬性來定義父的依賴版本pom並在每個模塊的dependency部分聲明瞭該屬性的依賴關係。
• 但是後來我想，讓我們按照Maven的最佳做法，在父項depencency-managent中聲明依賴項和版本，並從子項目depencency s中刪除版本標籤。

（之前）我用maven-project-info-reports-plugin:dependency-convergence報告來發現版本衝突的傳遞依賴關係。爲了決定我可以「忽略」那個衝突，或者我必須做些事情來解決它。 （典型的我「忽略」bugfix級別的衝突（版本號delta 0.0.X），但花費更多時間在主要或次要更改級別的衝突上。

但是在將依賴關係移動到depencency-managent之後， maven-project-info-reports-plugin:dependency-convergence報告幾乎是空的，沒有發現任何問題。

如何Maven的強制實施插件與額外強制實施規則？

讓我們創建硒版本之間的小衝突由我們和PhantomJS所使用的作爲管理：
