Hello,
I'm testing installation of an extension with extension manager / extension
repository, on XE 4.3-milestone-2:
- deploy my extension (xar + deps) from maven to a local nexus
- import this extension into the extension repo in my xwiki
- try to install it with EM
I get a conflict:
Dependency [javax.jcr:jcr-2.0] is not compatible with core extension
[javax.jcr:jcr-1.0]
I'm trying to understand from where this come from actually. I don't have
it when I build XE war myself but I can find it in the wars on
http://maven.xwiki.org/snapshots/org/xwiki/enterprise/xwiki-enterprise-web/…
.
This dependency is a transitive dependency (runtime)
of a mstor library
needed by my app. Currently, it is used in xwiki in version 1.0.
I first tried to add an <exclusion> block for it in my pom.xml, redeployed,
reimported, reinstalled, with same result.
Yes EM does not support exclusions. It's hard to handle in such an
environment where you potentially have several extension depending on the
same thing.
I then added jcr 1.0 in a dependencyManagement section
in order to override
version 2.0 brought by mstor, but again with same result.
Same thing, right now when EM is looking at your transitive dependencies it
lost the dependencyManagement from your pom.xml already.
BTW, additionally, the folder targeted by
xwiki.data.dir remains empty ...
Seems a bit strange.
Maybe it's set in your xwiki.properties files.
How can I solve this issue ?
Not an easy one.
I can think of several things:
* upgrade the jcr version in XE (I'm trying to look at what this means
exactly)
* have a custom version of your dependency with a different version of jcr
deployed somewhere like http://maven.xwiki.org/externals/ (not very nice)
* add support for a kind of exclusion/dependency overrides in EM
You sure your dependency would fully work with jcr-1.0 ? What is this
dependency by the way ?
Thanks,
Jeremie
