.ClassNotFoundException( org.apache.lucene.codecs.lucene50.Lucene50TermVectorsFormat) while using "com.mgmtp.a12.dataservices"

I’m using A12 in my Springboot- Applikation with the following versions of A12-Components:

  • version(‘base’, ‘26.3.0’)
  • version(‘form-engine’, ‘35.1.0’)
  • version(‘kernel’, ‘27.5.1’)
  • version(‘uaa’, ‘6.1.2’)
  • version(‘dataservices’, ‘35.0.5’)

the main reason for Failure is that the bean of SearchService in the class “com.mgmtp.a12.dataservices.autoconfigure.search.internal.SearchServiceConfiguration” couldn’t been instantiated due to failure in “com.mgmtp.a12.dataservices.search.internal.lucene.LuceneSearchServiceFactory” see the attached log file for more information.

Hi @malek-linked-anchor,

This error occurs when different version of solr or lucene are being set by the client project. Please use the versions which we deliver

luceneVersion = "9.3.0"
solrVersion = "9.1.1"

This answer is valid for Data services 32.2 - 36.0

i have explicitly added the following dependecies and it works now, thanks :+1:

implementation group: ‘org.apache.lucene’, name: ‘lucene-core’, version: ‘9.3.0’
implementation group: ‘org.apache.solr’, name: ‘solr-core’, version: ‘9.1.1’

however i noticed that the “org.apache.solr.solr-core:9.1.1” has 2 Vulnerabilities
[CVE-2023-26049]
[CVE-2023-26048]

https://mvnrepository.com/artifact/org.apache.solr/solr-core/9.1.1
so is it the right dependency that i need to pull?

JFYI. We had a problem, that our used Spring-Boot-BOM is applying an older solr version and because we never specified the solr version by our own, the spring-boot-bom one was used.

Maybe it could be the same problem that you had here :slight_smile:
