创建OrientDB数据库时出现意外异常

Question

我是OrientDB的新手，我正在尝试使用java代码创建数据库。我使用Play框架构建应用程序，但运行代码时会显示以下异常：

OdbConfig coredb = new OdbConfig("coredb"); //coredb.url = "plocal:databases/coredb";
try{
        new ODatabaseDocumentTx(coredb.url).create();
        System.out.print("Database Created");
    }
    catch(Exception e){
        System.out.print("ALREADY CREATED DATABASES");
        System.out.print(e);    
    }

意外异常：

NoClassDefFoundError: Could not initialize class com.orientechnologies.orient.core.db.ODatabaseRecordThreadLocal
