Jobin Jacob Kavalam commented on MDEP-610:
------------------------------------------
[~michael-o] Following your suggestion adding "provided" scope fixes the
problem.

Why does this fix work though ?
> Dependency order : Depending on transitive version instead of declared based

> h3. *Overview :*
> The order of dependency declaration in the pom is taking precedence instead
> of depth. Check this sample :
> https://github.com/ProcrastinatorCp/maven-dependency-issue-poc
> h3. *Example Scenario :*
> There are two modules. *test-a* and *test-b*
> *test-a* (depends on javax.servlet-api:2.5)
> *test-b* (depends on test-a)
> I want to use 3.1.0 version of above library in test-b. However, if test-a is
> declared before ***javax.servlet-api*, executing *mvn clean package* fails.
> {code:xml}
> <!-- NG : Reads 2.5 version of javax.servlet-api -->
> <dependency>
> <groupId>com.cp.test</groupId>
> <artifactId>test-a</artifactId>
> <version>${com.cp.test.version}</version>
> </dependency>
> <dependency>
> <groupId>javax.servlet</groupId>
> <artifactId>javax.servlet-api</artifactId>
> <version>3.1.0</version>
> </dependency>
> {code}
> If I change the ordering, it works fine.
> {code:xml}
> <!-- OK : Reads 3.1.0 version of javax.servlet-api -->
> <dependency>
> <groupId>javax.servlet</groupId>
> <artifactId>javax.servlet-api</artifactId>
> <version>3.1.0</version>[link title|http://example.com]
> </dependency>
> <dependency>
> <groupId>com.cp.test</groupId>
> <artifactId>test-a</artifactId>
> <version>${com.cp.test.version}</version>
> </dependency>
> {code}
> The documentation at :
> [https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html]
> > the current pom's declaration takes precedence over its parent's
> declaration.
> However, current pom declaration is not taking precedence *when ordered
> differently* (as above pom)
> Could you please confirm.
