Eclipse / Maven：使用可重用库和相互依赖项目的最佳方法？

Question

我在.NET世界中经历了很长一段时间后才回到Java / Eclipse世界。我对Maven也有点新意并掌握它，但是有点困境...

我目前正在开发一些Spring-Boot服务。这两个都取决于我开发的新库，我计划在其他项目中重复使用。

为方便起见，我开始在一个空的基于POM的父项下设置3个eclipse项目作为模块：

父POM

1. Service1 POM
2. LibB POM
3. LibA POM

LibB依赖于LibA，Service1依赖于LibA和LibB。

但是，后来需要Service2，这将取决于LibA。

所以，我决定摆脱父POM并制作Service1，LibA，LibB和现在的Service2独立的eclipse / maven项目。我认为这也允许我在Git中独立管理它们。

我尝试定义项目内存储库，我可以在Servcie1，Servcie2和LibB中包含LibA和LibB jar（因为LibB依赖于LibA）。然而，eclipse / maven似乎没有接受这个...而不是拿起罐子，它似乎直接引用了lib项目（见截图）。

这里最好的方法是什么？
