gRPC and Java Diamond Dependency Conflicts
summary
Explains how increasing framework integration creates complex Java dependency graphs that lead to diamond dependency conflicts causing runtime NoSuchMethodError and NoClassDefFoundError for gRPC, GAX, and OpenCensus. Describes the root causes (the anatomy) of these gRPC-related library conflicts and presents Google’s best practices for Java libraries plus how to use Linkage Checker to detect such conflicts in Java projects.
