   A Java application uses Maven. It depends on library A version 1.0.0, which depends on library C version 1.0.0. It also depends on library B version 2.0.0, which depends on library C version 2.0.0. The application code directly uses a class from C that is only available in version 2.0.0. The build succeeds, but at runtime a NoClassDefFoundError occurs. What is the most likely cause and the best fix?

   • AThe application should declare C as a runtime-scope dependency to ensure the newest version is used
   • BMaven selected C 2.0.0 because B is declared after A; exclude C from A
   • CMaven selected C 1.0.0 because A is declared before B; add an explicit dependency on C 2.0.0
   • DMaven failed to resolve the conflict, so the build should have failed; run 'mvn dependency:tree' and force C 2.0.0

   A Java application uses Maven. It directly depends on library A version 1.0.0, which transitively depends on library C version 1.2.0. The application also directly depends on library B version 2.0.0, which transitively depends on library C version 1.5.0. The application code uses a method from C that was introduced in version 1.5.0. The build succeeds, but at runtime a NoSuchMethodError occurs. What is the most likely cause and the best fix?

   • AMaven's nearest-wins mediation selected C 1.2.0 because A is declared before B; add an explicit dependency on C 1.5.0
   • BMaven selected C 1.5.0 but the application compiled against C 1.2.0; force an upgrade of A to a version that uses C 1.5.0
   • CMaven's dependency convergence failed, so the build should have failed; run 'mvn dependency:tree' and exclude C from A
   • DThe application should declare C as a test-scoped dependency to ensure the newest version is used at runtime

   A developer wants to share a reusable Java library with other teams in the company. They want to make it easy for other Maven projects to include the library and automatically get its dependencies. What should they do?

   • APublish the source code to a shared Git repository and ask teams to build it themselves
   • BPublish the library as a JAR to an internal Maven repository like Nexus or Artifactory
   • CCreate a Docker image with the library and have teams pull it
   • DCopy the compiled JAR to a shared network drive and ask teams to add it to their classpath
