播放2.5.3/Ebean: NoSuchMethodError: NoSuchMethodError：

Question

我使用的是Play 2.5.3框架，不管出于什么原因，Ebean在为本地(内存中)数据库创建演化时似乎失败了。这是完整的堆栈跟踪。

在谷歌上搜索这个异常让我几乎没有任何信息。

在我的"application.conf“文件中

ebean.default = ["models.*"]

    db {
      # You can declare as many datasources as you want.
      # By convention, the default datasource is named `default`

      # https://www.playframework.com/documentation/latest/Developing-with-the-H2-Database
      default.driver = org.h2.Driver
      default.url = "jdbc:h2:mem:play"
      default.username = sa
      default.password = ""

      # You can turn on SQL logging for any datasource
      # https://www.playframework.com/documentation/latest/Highlights25#Logging-SQL-statements
      #default.logSql=true
    }

这似乎是其他人所用的。我的ebean.properties文件，我认为这也可能是问题所在，只是包含了

ebean.namingconvention=com.avaje.ebean.config.MatchingNamingConvention

我的build.sbt文件如下所示：

name := """Project-CS2340"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)

resolvers ++= Seq(
  "webjars"    at "http://webjars.github.com/m2"
)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs,
  "org.webjars"               %% "webjars-play"       % "2.3.0",
  "org.webjars"               % "bootstrap"           % "3.0.0" exclude("org.webjars", "jquery"),
  "org.webjars"               % "jquery"              % "1.8.3",
  "org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.6.2"
)

playEbeanDebugLevel := 4

fork in run := true

今天早些时候，应用程序没有出错，我想我在休息时更改了一些东西并忘记了它。不知道，说实话。

Answer 1

替换ebean文件中的build.sbt库依赖项

"org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.6.2"

使用以下内容

"org.avaje" % "ebean" % "2.7.3"

祝你好运
