I created a service, async, impl for an rpc service. However, when I go to do the gwt compile (I'm using Eclispe Indigo with the gwt 2.4 plugin) I'm getting these errors:
Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors.

I'm not sure what is causing this? I'm not getting any compile errors under Eclipse, but something isn't setup right for the RPC service apparently.
Any ideas as to what the problem is?
It seems, you use the InputStream class somewhere in your client side code. But in client side code you are restricted to the classes mentioned in the JRE Emulation Reference.

i'm struggling since a couple of days ago in the attempt to resuscitate an old GWT application (which version is not updatable due to budget reasons).
In particular i've found several issues during the compilation phase.
This is what is blocking me:
Compiling module OctoMonitor Validating units: Ignored 200 units with compilation errors in first pass. Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors. Finding entry point classes [ERROR] Unable to find type 'com.lynxspa.octomonitor.frontend.client.OctoMonitorEntryPoint' [ERROR] Hint: Check that the type name 'com.lynxspa.octomonitor.frontend.client.OctoMonitorEntryPoint' is really what you meant [ERROR] Hint: Check that your classpath includes all required source roots [ERROR] Compiler returned false [WARN] continuing to serve previous version
I've checked my source folder (which is referred in classpath) and my .gwt.xml file is in the parent folder of my EntryPoint class.
source folder:
.gwt.xml file
client folder (containing EntryPoint Class)
I've also checked in project > preference > build path > source that every entry does not have any excluded resource anymore.
Ideas?
I want to use MaterialCarousel on my project and hence I think I set up my project accordingly. Here is what I am getting while I tried to compile.

GWT 2.7 does not support Java 8, and so does not support any recent build of GWT Material Design. GWT 2.8.0 was released in 2016, and the latest version as of this answer is 2.8.2, and generally should be used instead of an earlier 2.8 build.
I am trying to compile a GWT project but I am getting the following error: Can anyone please explain if I am missing anything? I have downloaded the GWT plugins for the eclipse.

I'm trying to start using GWTQuery in a GWT project.
I've created sample GWT project in Eclipse
Added gwtquery-1.3.2.jar
into war/WEB-INF/lib
Edited Myproject.gwt.xml (added <inherits name='com.google.gwt.query.Query'/>)
When I compile the project it writes a lot of deffered errors but at the end it comes with:

What I'm doing wrong?
Check your version of gwt, you have to update to GWT-2.5.x. because this artifact of gquery has a undesired dependency of it. There are two GWT.java classes in 2.5, and gquery is depending of the new com.google.gwt.core.shared by mistake.
Open an issue at the gwtquery site becasuse this release should work with older gwt version as well.
You could also change the gquery version to 1.3.1 or 1.4.0-SNAPSHOT
Update: I've just deprecated version 1.3.2, and released 1.3.3 which compiles with previous gwt versions
When I build the war file for deployment (ant war), the GWT compiler acts as if it has never heard of java.io.Reader or java.io.BufferedReader. When I make the development build for devmode (ant javac), they build just fine. I'm using GWT 2.4.0. Does anyone know what is going on?

Not the complete package java.io is supported by GWT.
See the JRE Emulation Reference for details
The client-side of GWT does not have access to the whole Java API. java.io is one of them.
When you run or compile it will give you did you forget to inherit a required module? error. But you can definitely use it on the server-side of GWT. You can find the list of classes that can be used at client-side here.
