[shrinkwrap-issues] [JBoss JIRA] (SHRINKWRAP-466) Maven dependency resolution ignores transitive exclusions

[Ken H (JIRA)]

    [ https://issues.jboss.org/browse/SHRINKWRAP-466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12809217#comment-12809217 ] 

Ken H commented on SHRINKWRAP-466:
----------------------------------

I apologize in advance for not having an example. If transitive exclusions are not captured in any test case then there should likely be one created.

> Expected way to build dependency list:
> {code}
> File[] dependencyFiles = Maven.resolver().loadPomFromFile("pom.xml")
> 			.importRuntimeAndTestDependencies()
> 			.resolve().withTransitivity().asFile();
> {code}
> However, this results in antlr still being added to the dependency list and the resulting WebArchive.
> My temporary workaround is to explicitly exclude the G:A:
> {code}
> File[] dependencyFiles = Maven.resolver().loadPomFromFile("pom.xml")
> 			.importRuntimeAndTestDependencies()
> 			.resolve()
> 			.using( new RejectDependenciesStrategy(false, "org.antlr:antlr", "antlr:antlr") )
> 			.withTransitivity().asFile();
> {code}
> Also note that the false is required in the RejectDependenciesStrategy. Without it, all (yes, all) transitive dependencies are ignored. This may be a separate issue but I want to mention it for anyone attempting this workaround.
