while this error makes sense due to the breakouts happening after version 1.2.1, the main readme shows that including the base API jar should work via buildscript.
additionally, the item component is only at version 2.3.0 and does not contain some critical fixes between 2.3.0 and 2.3.4

Adding the repository and dependency clauses to the build script using the current version (2.3.4) in releases gives the error:

`A problem occurred configuring root project 'LivingItems'.

Possible solution:
` - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

Update: The maven does now contain current releases, however the main module's POM file does not export dependencies on the sub-modules.

yep, thats what i ended up doing, but i figured i would open an issue since people are directed to do it the other way

yes, the current build scripts are broken, I haven't had time to fix that.

use JitPack for now

Fixed in #21

not fixed in #21

#22 updated the readme to use jitpack instead of the maven, tho that is only a temporary solution.
