I'm using the Play 2.5.3 framework, and for whatever reason Ebean seems to be failing while creating evolutions for my local (in memory) database. Here's the full stack trace.

Googling this exception got me next to no information.
In my "application.conf" file,
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
}
which seems to be what everyone else uses. My ebean.properties file, which I thought also may be the problem, simply contains
ebean.namingconvention=com.avaje.ebean.config.MatchingNamingConvention
My build.sbt file looks as follows:
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
Earlier today, the application worked without error, and I suppose I changed something and forgot about it while taking a break. No idea, honestly.
Replace the library dependency of ebean in your build.sbt file
"org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.6.2"
with the following
"org.avaje" % "ebean" % "2.7.3"
Have a good luck
