GWT 2.8.0-SNAPSHOT jsinterop missing module

[geek.m...@gmail.com]

Hi, I'm using the GWT 2.8.0-SNAPSHOT along with the Mojo GWT plugin (same version). Been working fine all week, but today I suddenly get this error message when doing a build: 

[INFO] --- gwt-maven-plugin:2.8.0-SNAPSHOT:compile (default) @ ritual-designer-bs ---

[INFO] Loading inherited module 'com.mjeffw.gurps.ritualdesigner.RitualDesignerBS'

[INFO]    Loading inherited module 'com.google.gwt.core.Core'

[INFO]       Loading inherited module 'jsinterop.annotations.Annotations'

[INFO]          [ERROR] Unable to find 'jsinterop/annotations/Annotations.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Any ideas on how to solve this?

[Thomas Broyer]

Make sure your dependencies are up-to-date and all present in the classpath (there's a new com.google.jsinterop:jsinterop-annotations artifact that com.google.gwt:gwt-user depends on)

[geek.m...@gmail.com]

Everything is up-to-date - I have made no changes, except to do a new mvn install. I just did a Maven > Update project, and a mvn clean, followed by a mvn install, and its still broken.

Here's the content of my pom.xml:

Any ideas on what is going on here would be appreciated!

I solve this issue myself by switching to gwt-2.8.0-beta1 and adding the declarations to my POM to use the 2.8.0-SNAPSHOT version of the plugin with a different version of GWT.

[Thomas Broyer]

Do you have $M2_HOME/repository/com/google/jsinterop/jsinterop-annotations/jsinterop-annotations-*-sources.jar in the classpath? (as should be seen in the Maven error output)

[Ali Akhtar]

I'm also encountering this issue with sandbox. The /home/ali/.m2/repository/com/google/jsinterop/jsinterop/1.0.0-SNAPSHOT contains only pom files, no jars. I'm attempting to upgrade - anyone know which maven repository contains the snapshot version of the maven plugin, or does it have to be installed via manual compile (Yay - not)?

[Ali Akhtar]

sandbox = snapshot

This is normal: the JAR is com.google.jsinterop:jsinterop-annotations.

com.google.jsinterop:jsinterop is only a parent POM (just like com.google.gwt:gwt and com.google.web.bindery:requestfactory)

[Ali Akhtar]

I'm still getting the same error as the OP on snapshot though. But switching to beta fixed it - however I can't find the maven plugin's snapshot / beta version on any repo, I had to compile / install it locally. Is it on any repos?
