gRPC and Google Guava version
The new gRPC version (0.12.0) requires strong own Guava version which is
20.0, however we have an import with version 19.0 in Camel parent which
cause transient dependency problem in the custom/sample projects importing
What do you think about potential sulitions:
1. Add documentation note that users must add following line to custom
overriding default guava version.
2. Update current google-guava-version in parent from 19.0 to 20.0 which
could relate to the potential problems in other components
3. Play with maven enforcer plugin or suggest another solution.
Thanks in advance.
