c# - Duplicate key error with SonarQube 5.2

Question

I've been trying out SonarQube 5.2, but I'm getting errors such as these:

org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  
Cause:com.microsoft.sqlserver.jdbc.SQLServerException: Cannot insert duplicate key row in object 'dbo.projects' with unique index 'projects_uuid'. The duplicate key value is (AVDTnvuxTcMzGBo2P2Fw).
### The error may involve org.sonar.db.component.ComponentMapper.insert-Inline
### The error occurred while setting parameters
### Cause: com.microsoft.sqlserver.jdbc.SQLServerException: Cannot insert duplicate key row in object 'dbo.projects' with unique index 'projects_uuid'. The duplicate key value is (AVDTnvuxTcMzGBo2P2Fw).

This only occurs if the solution I'm trying to analyse has more than one project. The same projects analyze just fine with SonarQube 5.1.2. I have the following configuration:

• SonarQube 5.2 (with a SQL Server 2012 database)
• C# 4.3
• Java 3.7
• LDAP 1.5
• Git 1.1
• SVN 1.2
• JavaScript 2.8

Anyone else ran into this problem?

Answer 1

The issue is coming from the fact that db and tables must be case sensitive.
