noClassDefFoundError io.ebean.Ebean

[Flo354]

Hi,

I can't start play 2.6.11 with sbt 0.13.16, scala 2.12.4 and play-ebean 4.1.0.
I get the following stack trace :

CreationException: Unable to create injector, see the following errors:

2 errors

There is no error with play-ebean 4.0.6.

[mschoenlaub]

I have the same problem. Have you found out anything more about it?

[Flo354]

Nope :(

[marcospereira]

Hi @Flo354,

Could you please provide a sample project that reproduces the error?

Best.

Hi @marcospereira

I found a solution to my problem, it seems to be related to a wrong statement in the documentation. I wrote it here: #457

I have two databases, db.development and db.production.

While, this page https://www.playframework.com/documentation/2.6.x/JavaEbean tells:
This defines a default Ebean server, using the default data source, which must be properly configured. You can also override the name of the default Ebean server by configuring ebeanconfig.datasource.default property

The property to define is not ebeanconfig.datasource.default but play.ebean.defaultDatasource

Found this here: https://stackoverflow.com/a/31070658

[marcospereira]

Thank you, @Flo354.

Do you want to submit a PR to fix the docs? The file for that page is here:

https://github.com/playframework/play-ebean/blob/master/docs/manual/working/javaGuide/main/sql/JavaEbean.md

Best.

I am experiencing the same error. Versions used:

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.6.20")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "4.1.3")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.2.2")

I just have just one DB, configured via `db.default.url=mysql://user:pw@localhost/dbname. In DEV mode everything works OK, the error only appears in PROD mode :-/

Did anyone find the root cause of this error?

[joschi]

The solution proposed by @Flo354 worked in our case, in which we had the same problem.

# https://github.com/playframework/play-ebean/issues/145#issuecomment-415402030
play.ebean.defaultDatasource = "default"
ebeanconfig.datasource.default = "default"

[joschi]

It turns out that these settings didn't solve the issue.

Right now it's not possible to effectively reproduce the issue or come to a lasting solution. 😞

[mkurz]

Hey guys, is this still a problem with newer Play and play-ebean releases?

btw, I think #457 is a duplicate (?)
