Karl Heinz Marbaise updated MNG-6699:
-------------------------------------
Fix Version/s: 4.0.x-candidate
> Inherit dependencies from a WAR type dependency.
> ------------------------------------------------
>
> Key: MNG-6699
> URL: https://issues.apache.org/jira/browse/MNG-6699
> Project: Maven
> Issue Type: Improvement
> Components: Dependencies
> Reporter: Frederik Boster
> Priority: Major
> Fix For: 4.0.x-candidate
>
>
> Given we have a Maven project, which produces a WAR overlay:
> {code:java}
> <project>
> [...]
> <packaging>war</packaging>
> [...]
> <dependencies>
> <dependency>
> <groupId>com.example</groupId>
> <artifactId>my-base-war</artifactId>
> <type>war</type>
> </dependency>
> </dependencies>
> [...]
> </project>
> {code}
> The dependency and dependency management declarations of
> com.example:my-base-war are not inherited by the overlay.
> The use-case is to create a WAR for Tomcat (as base war) and to enhance it
> with additional Jars for specific cloud providers like Azure and AWS via
> overlays.
> The missing inheritance of dependencies and dependency management results in:
> * maven-war-plugin fails with error "webxml attribute is required", because
> the servlet-api dependency is missing
> ** Workaround: specify `failOnMissingWebXml = false` in maven-war-plugin
> * Dependency Jars being packaged multiple times in different versions
> although already provided by the base war
> ** Workaround: Setting those dependencies to `provided` in the overlay.
> In my opinion the dependencies and dependency management of a WAR shall be
> taken into account by Maven in the same way as for Jars (i.e. fat-jars) to
> provide a coherent inheritance concept.
