Hello Team,

Can anyone please assist.

My solution was download the zip file. In the pom file, there is a <sonar.buildVersion>. Updated to your current build version, then compile it. Take the compiled jar file and paste it into SonarQube/extensions/plugins folder.

I will add the sonar versions requirenenrs to the Readme.

I created a wiki page with the prerequisites:
https://github.com/EXXETA/sonar-esql-plugin/wiki

There is no version specialised for sonar 7.4
If you need that I can create a version 1.1.4 or so supporting sonar 7.4

Please check if this is working for you:
https://github.com/EXXETA/sonar-msgflow-plugin/releases/tag/1.1.4-RC1

@ThomasPohl I faced the same error with Sonar 8.6 and 1.1.4-RC1 is working for me. Thank you!

[ThomasPohl]

@andrewfemin Great. I'll create releases from the candidates.
