When creating a VDB with a SAP HANA datasource, the correct maven dependency according to the docs is com.sap.cloud.db.jdbc:ngdbc:pom:2.4.76. However, with that dependency included in the VDB CR, I get the following error on VDB start:
Caused by: java.lang.RuntimeException: Failed to get driver instance for jdbcUrl=jdbc:sap://54.187.27.202:30015 at com.zaxxer.hikari.util.DriverDataSource.<init>(DriverDataSource.java:114) ~[HikariCP-3.4.2.jar!/:na] at com.zaxxer.hikari.pool.PoolBase.initializeDataSource(PoolBase.java:321) ~[HikariCP-3.4.2.jar!/:na] at com.zaxxer.hikari.pool.PoolBase.<init>(PoolBase.java:110) ~[HikariCP-3.4.2.jar!/:na] at com.zaxxer.hikari.pool.HikariPool.<init>(HikariPool.java:108) ~[HikariCP-3.4.2.jar!/:na] at com.zaxxer.hikari.HikariDataSource.getConnection(HikariDataSource.java:112) ~[HikariCP-3.4.2.jar!/:na] at org.springframework.jdbc.datasource.DataSourceUtils.fetchConnection(DataSourceUtils.java:158) ~[spring-jdbc-5.2.5.RELEASE.jar!/:5.2.5.RELEASE] at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:116) ~[spring-jdbc-5.2.5.RELEASE.jar!/:5.2.5.RELEASE] at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:79) ~[spring-jdbc-5.2.5.RELEASE.jar!/:5.2.5.RELEASE] at org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:324) ~[spring-jdbc-5.2.5.RELEASE.jar!/:5.2.5.RELEASE] at org.springframework.boot.jdbc.EmbeddedDatabaseConnection.isEmbedded(EmbeddedDatabaseConnection.java:120) ~[spring-boot-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.DataSourceInitializedPublisher.lambda$isInitializingDatabase$0(DataSourceInitializedPublisher.java:116) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.HibernateSettings.getDdlAuto(HibernateSettings.java:41) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.HibernateProperties.determineDdlAuto(HibernateProperties.java:136) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.HibernateProperties.getAdditionalProperties(HibernateProperties.java:102) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.HibernateProperties.determineHibernateProperties(HibernateProperties.java:94) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.DataSourceInitializedPublisher.isInitializingDatabase(DataSourceInitializedPublisher.java:118) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.DataSourceInitializedPublisher.publishEventIfRequired(DataSourceInitializedPublisher.java:98) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.boot.autoconfigure.orm.jpa.DataSourceInitializedPublisher.postProcessAfterInitialization(DataSourceInitializedPublisher.java:90) ~[spring-boot-autoconfigure-2.2.6.RELEASE.jar!/:2.2.6.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:431) ~[spring-beans-5.2.3.RELEASE.jar!/:5.2.3.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1800) ~[spring-beans-5.2.3.RELEASE.jar!/:5.2.3.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:595) ~[spring-beans-5.2.3.RELEASE.jar!/:5.2.3.RELEASE] ... 23 common frames omitted Caused by: java.sql.SQLException: No suitable driver at java.sql/java.sql.DriverManager.getDriver(DriverManager.java:298) ~[java.sql:na] at com.zaxxer.hikari.util.DriverDataSource.<init>(DriverDataSource.java:106) ~[HikariCP-3.4.2.jar!/:na] ... 43 common frames omitted
A workaroud for me was to include the original driver we used in legacy DV for connecting to HANA (version 1.00.102, obtained from our private nexus repo). This might be due to the fact that our instance of HANA is also version 1.00.x. QE currently does not have access to a newer HANA instance.
Also note that with the above workaround, both the drivers need to be specified as dependencies, otherwise the VDB build will fail with the missing ngdbc dependency.
