> Key: CONNECTORS-1712
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1712
> Project: ManifoldCF
> Issue Type: Bug
> Components: API
> Affects Versions: ManifoldCF 2.22
> Reporter: Julien Massiera
> Assignee: Karl Wright
> Priority: Critical

> In the mcf-crawler-ui, we cannot enter in edition mode for any connector because there is a problem with Velocity.
> We obtain the following error in the logs:
>
> {code:java}
> java.lang.NoSuchMethodError: 'void org.apache.velocity.app.VelocityEngine.setExtendedProperties(org.apache.commons.collections.ExtendedProperties)'

> After some investigations it seems related to the updated velocity lib from velocity-1.7 to velocity-engine-core-2.3
> The first problem found is that the old velocity version libs and their dependencies are still present in the MCF build for the MCF Agent AND the mcf-crawler-ui.
> The concerned libs are:
> - commons-collections-3.2.2.jar
> - commons-lang-2.6.jar
> - velocity-1.7.jar
>
> The second problem is that with the new velocity version, the way to set properties to the engine has changed. So the code in the org.apache.manifoldcf.core.i18n.Messages.createVelocityEngine method is no longer valid and needs to be updated to fit with the new way which is:
> {code:java}
> VelocityEngine engine = new VelocityEngine();
> Properties configuration = new Properties();
> configuration.setProperty(VelocityEngine.RESOURCE_LOADER,"mcf");
> ....
> engine.setProperties(configuration); {code}
