Maven CycleException

I am currently making a library for my upcoming spigot plugins. But you won't require any knowledge of that since this is more dependent on maven issues



So firstly I'd like to give the source



I have multiple modules: Library, v1_13_R1, v1_13_R2, the reason for multiple v1_13_R etc. is because Maven won't allow you to implement multiple versions of the same dependency. And its crucial for the functions of these modules to have the right version as the packages have the version names in them. EDIT 1 I've seen that this may sound confusing so: The reason why its possible to have multiple of the same library in one jar(Not module) is possible because my system won't initiate the class containing imports that aren't provided as I first detect which version is used. This way I can make it multi-version. I hope this clears up some of the confusing regarding this.



So if I clean package from root then It will create 3 jars, but none of them contains all 3 modules, which is what I need. And if I make the version dependent modules a dependency in my Library module, then I'll get a CycleException.



1) any idea on how to fix this?


or optionally:


2) is there any better project structure possible?



Any help would be really appreciated, thanks in advance



EDIT I still need a good answer as its frustrating me at the moment since nothing works. So if you have any knowledge on how to make such a project structure work please tell me.

  • It does not make sense having different versions of the same library on a classpath. This is basic Java and nothing to do with Maven. Furthermore I've seen a package with <type>javadoc</type> which does not exist in Maven. But what exists would be a javadoc package which has a classifier <classifier>javadoc</classifier>...and why is the javadoc part defined as <scope>provided</scope> which does not make sense..?

  • It does, as NMS(The part I am trying do get right) updates its package name with each version for example for v1_13_R1 the package name is: net.minecraft.server.v1_13_R1 and for v1_13_R2 it is: net.minecraft.server.v1_13_R2 and I need to make multiple modules since I can not make one module have multiple versions on the same artifact. Also I have no dependency as type javadoc

  • So, are you saying that if you identify your modules V1_13_R1 and V1_13_R2 with the same groupId and artifactId, but different version numbers, you cannot get Maven to have Library depend on both of them?

  • No the library that those modules use cannot be added as dependency with multiple versions in the same module
