I am trying to install wikidata-query-rdf (https://github.com/wikimedia/wikidata-query-rdf) and there is a failure with Blazegraph : 

git clone https://gerrit.wikimedia.org/r/wikidata/query/rdf wikidata-query-rdf
cd wikidata-query-rdf
sudo mvn install

I first get this kind of warning : [WARNING] The POM for com.blazegraph:bigdata-cache:jar:2.1.5-SNAPSHOT is missing, no dependency information available

And then :

  • The answer is quite clear, or not? Some dependencies can't be found by Maven. You can see that it is looking in a repository where only releases but no SNAPSHOTS are available: https://archiva.wikimedia.org/repository/mirrored/com/blazegraph/bigdata-core/ – UninformedUser Dec 19 '17 at 11:52

Some dependencies can't be found by Maven. You can see that it is looking in a repository where only releases but no SNAPSHOTS are available.

You should add the SNAPSHOT repository to the parent pom.xml file:

<repositories>
       ....
  <repository>
            <id>wmf.snapshots</id>
            <url>https://archiva.wikimedia.org/repository/snapshots</url>
  </repository>
</repositories>

Or alternatively, change the Blazegraph dependency version property to latest release version:

<properties>
        <blazegraph.version>2.1.4</blazegraph.version>
        ...
</properties>

  • Thanks a lot ! What works also for me was to download an older version : https://github.com/wikimedia/wikidata-query-rdf/archive/0.2.1.zip – Thomas Scialom Dec 20 '17 at 13:29
