【问题描述】：
我正在尝试在 karaf 中部署一个包。我想在其中创建一个连接到 h2 数据库的流程引擎。我在 pom.xml 中有依赖项：
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.190</version>
</dependency>
在ini() 方法中，我尝试使用以下方法创建引擎进程：
ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
.setJdbcUrl("jdbc:h2:mem:my-own-db;DB_CLOSE_DELAY=1000")
.setJobExecutorActivate(true)
.buildProcessEngine();
不过，在 karaf 控制台中，当我部署捆绑包时出现错误：
