This quarter I hit a familiar wall: dependency hell.
Multiple transitive versions of Jackson caused random serialization bugs. I fixed it by:
- Using
mvn dependency:tree to inspect conflicts
- Explicitly excluding conflicting transitive deps
- Creating a central BOM for shared version controlHere's a quick snippet:
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.5.1</version> </dependency> <exclusions> <exclusion> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> </exclusion> </exclusions>
Dependency clarity = deployment stability.
