我是ebean和scala/akka的新手，並且試圖將最小案例類作爲ebean實體持久化。我的依賴關係如下：爲什麼我在增強ebean scala實體時得到java.lang.VerifyError
scalaVersion := "2.11.5"
libraryDependencies ++= Seq(
"com.typesafe.akka" %% "akka-actor" % "2.3.9",
"com.typesafe.akka" %% "akka-remote" % "2.3.9",
"com.typesafe.akka" %% "akka-cluster" % "2.3.9",
"com.typesafe.akka" %% "akka-testkit" % "2.3.9" % "test",
"org.scalatest" %% "scalatest" % "2.2.4" % "test",
"com.typesafe.slick" %% "slick" % "3.0.0",

"org.sorm-framework" % "sorm" % "0.3.18",
"org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.7.1",
"org.avaje.ebeanorm" % "avaje-ebeanorm-agent" % "4.5.3",
"org.avaje" % "avaje-agentloader" % "1.1.3",
"org.apache.commons" % "commons-pool2" % "2.0")
和我的實體：
package zw.co.esol.eswitch.model
import javax.persistence.Entity
import javax.persistence.Id
import com.avaje.ebean.Model
@Entity
case class Test(@Id id: Long, firstname: String) extends Model
和我的主：
object ApplicationMain extends App {
val system = ActorSystem("eswitch", ConfigFactory.load())
//system.logConfiguration()
// Load the agent into the running JVM process
if (!AgentLoader.loadAgentFromClasspath("avaje-ebeanorm-agent","debug=1;packages=zw.co.esol.eswitch.model.*")) {
println("avaje-ebeanorm-agent not found in classpath - not dynamically loaded");
}
EbeanDbServer.init
//more code follows.......
和我ebean初始化代碼：
object EbeanDbServer {
def init = {
// programmatically build a EbeanServer instance
// specify the configuration...
println("@@ Starting EbeanServer...")
var config = new ServerConfig();
config.setName("pgtest");
// Define DataSource parameters
var postgresDb = new DataSourceConfig();
postgresDb.setDriver("com.mysql.jdbc.Driver");
postgresDb.setUsername("user");
postgresDb.setPassword("password");
postgresDb.setUrl("jdbc:mysql://127.0.0.1:3306/eswitch");
postgresDb.setHeartbeatSql("select count(*) from message");
config.setDataSourceConfig(postgresDb);
// specify a JNDI DataSource
// config.setDataSourceJndiName("someJndiDataSourceName");
// set DDL options...
config.setDdlGenerate(false);
config.setDdlRun(false);
config.setDefaultServer(false);
config.setRegister(false);
var test = Test(1, "stan")
// automatically determine the DatabasePlatform
// using the jdbc driver
// config.setDatabasePlatform(new PostgresPlatform());
// specify the entity classes (and listeners etc)
// ... if these are not specified Ebean will search
// ... the classpath looking for entity classes.
config.addClass(classOf[Test]);
// specify jars to search for entity beans
// config.addJar("someJarThatContainsEntityBeans.jar");
// create the EbeanServer instance
val server: EbeanServer = EbeanServerFactory.create(config);
println("@@ EbeanServer started... : " + server.getName)
}
}
但我運行應用程序時獲取輸出：

我在Linux x86_64上使用Java版本「1.7.0_55」。
我會做什麼錯？我試圖尋找解決方案，但迄今爲止所見到的所有線程都無濟於事。
你有沒有找到任何解決方案？如果可以，我可以和我分享嗎？ – tg44
