[community edition] Solr doesn't start after migration from 7.3.0 to 23.4.1

jkb — Wed, 12 Feb 2025 10:18:13 GMT

Hello,

I have upgraded my communty edition to 23.4.1 on a Linux Devuan server (Debian like). Previously, solr ran fine. Now, search services fail and if I try to do a connction to localhost:8983/solr, I only obtain following error:

HTTP ERROR 500 Problem accessing /solr/. Reason: Server Error Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.alfresco.solr.AlfrescoSolrDataModel at org.alfresco.solr.security.SecretSharedPropertyCollector.lambda$static$1(SecretSharedPropertyCollector.java:74) at org.alfresco.solr.security.SecretSharedPropertyCollector.lambda$getProperty$4(SecretSharedPropertyCollector.java:118) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:195) at java.base/java.util.ArrayList$ArrayListSpliterator.tryAdvance(ArrayList.java:1632) at java.base/java.util.stream.ReferencePipeline.forEachWithCancel(ReferencePipeline.java:127)

Solr seems to be running:

and I have no error in solr log file prior to first access from Alfresco:

I suppose I have done a misconfiguration somewhere, but I'm unable to find where org.alfresco.solr.AlfrescoSolrDataModel is defined.

Help will be welcome,

Does your solr.in.cmd file have these params?

set SOLR_ALFRESCO_SECURECOMMS=secret
set SOLR_ALFRESCO_SECURECOMMS_SECRET=yoursecret

In my case if I don`t set up them at Solr side (even though they are defined at alfresco side in alfresco-global.properies) the requests fail with 403 status code. However the exception messages are not the same like yours...
