[jira] Commented: (MYFACES-2623) validation-api and el-api 2.2 should be optional dependencies with scope compile in myfaces-api

["Jakob Korherr (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/MYFACES-2623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12849339#action_12849339 ] 

Jakob Korherr commented on MYFACES-2623:
----------------------------------------

I almost forgot: the el-api dependency has to be put on top of the jsp-api dependency in the pom, because jsp-api also includes the el-api, however an older version of it.

If we don't do this, we will run into compilation errors with maven when using new features!

> Currently those two dependencies are defined messy. First they are defined in myfaces-core-project as optional which makes no sence since this project is just the super-project for api and impl and optional dependencies are not transitive. So this has to be removed here.
> Furthermore the definitions of validation-api and el-api in the pom of myfaces-api are not completely correct. They should have a scope of compile (default) and should have set optional to true instead of just provided or provided+optional (which is by the way not allowed).
> After this issue has been resolved el-api 2.2 will be available on the whole myfaces-api project, however keep in mind that you are only allowed to use the new methods (like getValueReference()) if you checked if the el-api 2.2 is really available first (via ExternalSpecifications). Otherwise you will end up in ClassNotFoundExceptions at runtime when el-api 2.2 is not available in the target system.
