Hi Erik. thanks for your help. I tried with solr.xml as follow
<solr> <property name="lucene.version" value="LUCENE_40"/> </solr> It fails with this exception Caused by: org.apache.solr.common.SolrException: No system property or default value specified for lucene.version value:${lucene.version} If I put this variable in core.porperties lucene.version=LUCENE_40. Do you know if this is a bug?
