我們是Sonar的新用戶，剛剛下載了v2.13.1，並開始使用它並與我們的項目合作。這很好，直到它開始慢慢運行，我意識到這是因爲我們仍然在包括德比運行。我們在同一個盒子上運行MySQL Server 5.1（以及TeamCity CI），所以我按照步驟設置了MySQL。使用MySQL 5.1的Sonar 2.13.1版本
- 我運行了
extras\database\mysql\create_database.sql來創建聲納用戶並分配權限。 我更新
conf\sonar.properties包括：sonar.jdbc.url: jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8 sonar.jdbc.driverClassName: com.mysql.jdbc.Driver sonar.jdbc.validationQuery: select 1我重新啓動聲納服務器並從該數據庫表中創建日誌看到，我可以通過瀏覽該數據庫獨立證實了這一點。
當我啓動服務器時，我得到的日誌中的以下內容：
2012.02.07 13:50:58 INFO o.s.c.p.Database Create JDBC datasource 2012.02.07 13:51:01 INFO org.sonar.INFO Initializing Hibernate 2012.02.07 13:51:11 INFO org.sonar.INFO Start services...當我運行我們TeamCity的配置，它是「
mvn clean install」接着是「mvn sonar:sonar」的目標，這在以前的工作德比下，我們構建成功完成，但聲納以下信息死亡：[14:11:24] [west-chai:my-project] [INFO] --- sonar-maven-plugin:2.0:sonar (default-cli) @ my-project --- [14:11:26] [west-chai:my-project] [INFO] Sonar version: 2.13.1 [14:11:29] [west-chai:my-project] [WARN] [14:11:29.403] Derby database should be used for evaluation purpose only [14:11:29] [west-chai:my-project] [INFO] [14:11:29.403] Create JDBC datasource [14:11:30] [west-chai:my-project] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0:sonar (default-cli) on project my-project: Can not execute Sonar [14:11:30] [INFO] ------------------------------------------------------------------------ [14:11:30] [INFO] Reactor Summary: [14:11:30] [INFO] [14:11:24] [west-chai:my-project] [INFO] --- sonar-maven-plugin:2.0:sonar (default-cli) @ my-project --- [14:11:26] [west-chai:my-project] [INFO] Sonar version: 2.13.1 [14:11:29] [west-chai:my-project] [WARN] [14:11:29.403] Derby database should be used for evaluation purpose only [14:11:29] [west-chai:my-project] [INFO] [14:11:29.403] Create JDBC datasource [14:11:30] [west-chai:my-project] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0:sonar (default-cli) on project my-project: Can not execute Sonar [14:11:30] [INFO] ------------------------------------------------------------------------ [14:11:30] [INFO] Reactor Summary: [14:11:30] [INFO] [14:11:30] [INFO] PROJECT COMPONENT 1 ...................

錯誤行日在後面提到端口1527，它被註釋掉的Derby配置行引用。
[14:11:31] [ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0:sonar (default-cli) on project my-project: Can not execute Sonar: PicoLifecycleException: method 'public final org.sonar.core.persistence.DefaultDatabase org.sonar.core.persistence.DefaultDatabase.start()', instance '[email protected], java.lang.RuntimeException: wrapper: Fail to connect to database: Cannot create PoolableConnectionFactory (java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.) -> [Help 1]
如果我註釋掉sonar.jdbc線以上和還原以下行，然後我們兩個「mvn clean install」和「mvn sonar:sonar」成功完成。
sonar.jdbc.url: jdbc:derby://localhost:152/sonar;create=true
sonar.jdbc.driverClassName: org.apache.derby.jdbc.ClientDriver
sonar.jdbc.validationQuery: values(1)
是否有Maven的目標比由聲納服務器直接使用不同的配置？是否有明確的方法來確定哪個JDBC數據源正在連接到？
