Helly everyone
I'm currently also stuck with the "No index provider 'lucene' found"
error that you all seem to have been able to work around.
I have built and installed the 1.5-SNAPSHOT kernel from the
bundle-friendly-classloader branch and installed it locally (mvn
install).
When I run the neo4j-osgi tests I still get the mentioned lucene error:
...
[FelixDispatchQueue] DEBUG org.neo4j.examples.osgi.test-bundle -
BundleEvent STOPPED
ERROR: Bundle org.neo4j.examples.osgi.test-bundle [3] Error starting
file:bundles/org.neo4j.examples.osgi.test-bundle_0.1.0.SNAPSHOT.jar
(org.osgi.framework.BundleException: Activator start error in bundle
org.neo4j.examples.osgi.test-bundle [3].)
java.lang.IllegalArgumentException: No index provider 'lucene' found
at
org.neo4j.kernel.IndexManagerImpl.getIndexProvider(IndexManagerImpl.java:76)
...
Failed tests:
neo4jStartupTest(org.neo4j.examples.osgi.OSGiTest)
bundleStartupTest(org.neo4j.examples.osgi.OSGiTest)
Is there anything else I have to to so that I get the examples up and running?
Best regards,
James
