我对周期性依赖项目的m2e插件有问题。
首先，我知道循环依赖关系不好，maven也不允许这样做，应该避免使用依此类推，等等，但是我们的遗留项目已经进行了修饰，而没有更改项目结构（继续循环依赖关系。）]
以前，将每个项目添加到其他项目的构建路径并将循环依赖项构建路径问题设置为警告是解决方法。这样，我可以在一个项目中进行更改，然后立即在另一个项目中查看效果。
现在项目已被美化，我想通过启用m2e工作空间解析（通过选中“从工作空间项目中解决依赖关系”选项来实现相同的工作空间环境。）>]
在带有m2e版本1.7.0.20160603-1933的Eclipse Neon（版本：Neon.3版本（4.6.3）Build ID：20170314-1500）中，这是可能的。尽管构建路径中存在循环，但仍可以从工作空间项目中解决相应的maven依赖性。
但是，在eclipse 2019-09 R（版本：2019-09 R（4.13.0）Build ID：20190917-1200中使用m2e版本1.13.0.20190716-1624）和更高版本中，在无限循环中生成结果。对于两个周期项目MY PROJECT A和MY PROJECT B分别具有maven工件ID MYPROJECTAARTIFACTID，MYPROJECTBARTIFACTID，以下是从2019-09 R版本起无限构建的m2e日志（我无法从霓虹灯版本中收集日志）。
重复一遍，我知道maven本身不允许周期性的项目设置，但是通常Eclipse甚至允许具有maven性质的项目使用。
如何在最新的Eclipse版本中实现相同的目标？
