[cross-project-issues-dev] Is it acceptable to have two com.google.commo

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

In Indigo, the com.google.common.collect package was (and still is) 
provided by the com.google.collect plugin.

It is now also provided by the com.google.guava plugin.

For M4, Xtext 2.2.1 switched to Guava and so switched provider, but the 
old provider is still available in repositories for downstream projects 
that neglect to update their dependencies accurately.

As a consequence, the M4 OCL Tools contribution provides broken editors. 
Since these are technically 'Examples', a respin is clearly not merited, 
so MDT/OCL will be providing an M4a.

However it seems appropriate to at least warn the community of this 
hazard, and ask whether this is a serious breach of versioning principles.

    Regards
