You'll have to update things a bit of course as these generate WARs that
you run in development with the jetty-maven-plugin; for instance, using an
embedded server would require a dependency:unpack{,-dependencies} and/or
using the maven-assembly-plugin instead of using a war overlay.

Thanks Thomas, can you point me to any examples of GWT projects split into multiple maven modules? I'll head that route. Thanks again.

GWT 2.8.2 and Jetty Embedded - com.google.gwt.dev.jjs.InternalCompilerException: Error constructing Java AST
apache-jsp brings Eclipse JDT, which causes the conflict. As you're using Mojo's plugin for GWT,you can configure it to put GWT dependencies first in the classpath; that should fix the conflict. But you really should split this project into two or three modules, with separate dependency trees for client and server code. That would automatically clean all such conflicts. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

GWT 2.8.2 and Jetty Embedded - com.google.gwt.dev.jjs.InternalCompilerException: Error constructing Java AST
I've got a real simple scaled down GWT application (to illustrate the issue) with Jetty Embedded Server (9.4.7.v20170914), it can be downloaded here: This works fine when running under 2.7.0. Unfortunately, when I upgrade to 2.8.2, I'm getting an error during the GWT compilation stage. See below. Any suggestions in how I can fix this? It seems like there is a conflict between Jetty deps and GWT 2.8.2 deps and I probably need some kind of exclude, but I'm not super familiar with maven enough to tell it how to exclude what it needs so this compiles. The simple application be be downloaded from: https://www.dropbox.com/s/1myj5o3dpq9bzxt/gwt_jetty.zip?dl=0 Really appreciate any help in this.
