NoClassDefFoundError: org/apache/lucene/search/grouping/AbstractAllGroupHeadsCollector

[Barnabas Szasz <bs...@gmail.com>]

Hi,

I was creating a local instance and ran into this:

HTTP ERROR 500

Problem accessing /contenthub/contenthub/search/featured. Reason:

    org/apache/lucene/search/grouping/AbstractAllGroupHeadsCollector

Caused by:

java.lang.NoClassDefFoundError:
org/apache/lucene/search/grouping/AbstractAllGroupHeadsCollector
...

You can reproduce it on the demo site:
http://dev.iks-project.eu:8081/contenthub/contenthub/search/featured?queryTerm=paris&limit=3

Any idea why is this? Am I missing something in my local instance?

Thanks,
Barna

The cause is very simple. The Stanbol version of Solr does not include

    <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-grouping</artifactId>
        <version>${solr-version}</version>
    </dependency>

with revision http://svn.apache.org/viewvc?rev=1422913&view=rev I
added it (see also STANBOL-845)

In the dev server the new module is already deployed. If you update to
the current revision than it should also work locally

I will close the issue as soon as jenkins has validated the changes.

Thanks for reporting

best
Rupert
