The error is coming up with the shipped examples.

Same problem here

I think this repo is no longer maintained. Any alternative?

Check out my fork v0.0.21. You need my upgraded unpuzzle version 0.0.23.

I use the gradle
:publishToMavenLocal
target to bypass the bintray/mavencentral repository step for unpuzzle.

I'm interested in feedback if it works on your side.

Hi,

are there already some news when the bugfix will be released ?

[MarceloRuiz]

@bueli
Does your fork work with the latest versions of e(fx)clipse and Gradle? Any idea of when they'll be uploaded to the plugin repository? I have been trying to launch the application with the Diffplug's goomph but it does't work with e(fx)clipse applications and they don't seem to care about e(fx)clipse at all...
Thanks!

Hi @MarceloRuiz
No idea. Did you try it?
What was the result?

[MarceloRuiz]

Hi @bueli Thanks for getting back to me. I am quite new to this. I didn't try it. I downloaded your repository and it says wuff-0.0.21. I opened the MyEfxclipseApp example app folder and the gradle.properties shows wuff_version=0.0.14 and after executing it I was getting the same error described in the first post. I also updated the version to 0.0.21 but the error I get is 'Could not resolve org.akhikhl.wuff:wuff-plugin:0.0.21'
Thanks!

@numical thanks, that's pointed us in the right direction
