java.lang.NoSuchMethodError in JsonContext

[trane]

I successfully used the activator playground template a week ago, but now I am getting the following error: In a newly activator created playground: [error] (compile:swaggerParseSpec) java.lang.NoSuchMethodError: me.andrz.jackson.JsonContext.<init>(Ljava/io/File;I)V Which is called from https://github.com/zalando/api-first-hand/blob/master/swagger-model/src/main/scala/de/zalando/swagger/StrictParser.scala#L35

A few things I noticed:

• jackson-json-reference-core 0.2.1 just got rebuilt into maven central less than a day ago (no minor version bump for the new build, seems to just overwrite what was there).
• There really is no constructor with parameters (File, Int) for a JsonContext that I could find
• I get this error even when I have completely erased my ivy2 cache and run sbt clean, used a completely new copy of the activator template.

Here is the stack trace when running sbt compile

@trane hey, thank you very much for the bug report. We are currently redesigning the whole generated code for play content-negotiation and parsing, I'll take a look at this issue as a part of it

[zackangelo]

Also experiencing this issue.

[eyasuyuki]

I pushed this fix.

[slavaschmidt]

@eyasuyuki cool, thank you

[shuhei]

@slavaschmidt Would mind releasing the fix?

@eyasuyuki Thanks for the fix!

[slavaschmidt]

@shuhei sure, I need some short time to prepare other changes, the next version follows really soon. Sorry for letting you wait

Hi, I'm just getting started with Play and Swagger. I've generated a project using activator new and the api-first-hand template, and get the NoSuchMethod error when I run it. Has this fix been released yet ? If so, how can I get hold of the new template ?

Many thanks.

[slavaschmidt]

@Jack-Welch hey, sorry for the inconvenience. The fix has been released and I will update the activator template today.

[shuhei]

@slavaschmidt Thanks for releasing it!

[slavaschmidt]

@shuhei you're welcome, sorry it took so long

[slavaschmidt]

@Jack-Welch just published an updated template

Actually, you could just change the plugin version in project/plugins.sbt from 0.1.16 to 0.1.18 if you like

@slavaschmidt Many thanks - project now up and running.
