Question

我搜索了一种方法来获得一种依赖性收敛报告，该报告列出了dependency-management中定义的依赖关系，但是由具有不同版本的传递依赖关系引用。

我知道maven-project-info-reports-plugin:dependency-convergence，但这只列出dependency中定义的依赖关系（和传递依赖关系）之间的冲突，但是一旦我在dependency-management中定义了该依赖关系，它就会得到未列在报告中。

我只想要一份报告，如果发生这种“冲突”，我不想让构建失败。

背景：

我有一个Maven-Multi-Module项目：

以前我没有使用depencency-managent，但是我使用属性来定义父pom中的依赖版本，并使用该属性在每个模块的dependency部分中声明了依赖项。
但后来我想，让我们按照Maven的最佳做法，在父depencency-managent中声明依赖项和版本，并从子项目depencency中删除version-tag。

（以前）我使用maven-project-info-reports-plugin:dependency-convergence报告来发现版本冲突的传递依赖项。为了决定我可以“忽略”那个冲突，或者我必须做些什么来解决它。（典型的我“忽略”了bugfix级别的冲突（版本号delta 0.0.X），但是花费更多的时间来处理主要或次要变化级别的冲突。

但在我将依赖项移至depencency-managent后，maven-project-info-reports-plugin:dependency-convergence报告几乎为空，并未发现任何问题。

带有额外执行规则的Maven Enforcer插件怎么样？

让我们在由我们管理的Selenium版本与PhantomJS使用的版本之间产生一点冲突：

我希望这有助于实现您的目的。

警告：我发现这个strange little glitch在某些情况下会发生。但是，让它不要太麻烦你，基本上它很好用。
