Compatiblity issue with GWT 2.2. com.google.gwt.core.ext.typeinfo.JClassType #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Configure GWT 2.2.0
2.Compile GWT or mvn install
3.

What is the expected output? What do you see instead?
Successful compilation.

However, I get following error
java.lang.IncompatibleClassChangeError: Found interface 
com.google.gwt.core.ext.typeinfo.JClassType, but class was expected

What version of the product are you using? On what operating system?
1.0.3 / trunk / linux

Please provide any additional information below.
Apparently some classes changed in GWT 2.2 and you need to recompile your 
project with GWT 2.2. 

I've tried to compile your project with GWT 2.2, but run in other problems. 
Finally, I run into ClassNotFoundException for 
com.kfuntak.gwt.json.serialization.client.GWTProJsonSerializer while executing 
in Dev Environment.

Thanks for fixing that issue.
Kuno

This seems like a nice library, waiting for this issue to be fixed before I 
could use it :)

I am not able of reproducing the issue with the following configuration:

    gwt.version 2.1.1
    gwt-plugin.version 2.1.0-1
    gwtprojsonserializer.version 1.0.3

Can you please check in a sample project that fails?

For all you guys complaining about incompatibility with GWT 2.2, if you just 
download the source and compile it against 2.2, you'll get a JAR that will work 
with GWT 2.2.0. I have already built it and tested it myself, not sure about 
the licensing and stuff. If it's OK with the guys here, i can attach it. Let me 
know.

It would be indeed great if you could give us the JAR as well as the modified 
source code. I'll also check it against GWT 2.0 and 2.1 and then probably ask 
for a new release.

Thank you

I've attached the Jar file, didn't modify any source code. Just changed POM.xml 
to compile it against GWT 2.2.0.
Let me know how it goes. Sorry for the delayed reply.

It is not working for me, it goes like:

Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:1.2:compile (default) 
on project gwtprojsonserializer: artifact not found - Failure to find 
com.google.gwt:gwt-dev:jar:mac:2.2.0 in http://repo1.maven.org/maven2 was

OK fixed all these errors and commited revision 130.

As of that revision, the serializer works with GWT 2.2 but does not work with 
GWT 2.1 anymore; we get messages like:

In my opinion, GWT 2.1 support should be dropped, and basta. If Google has 
decided that GWT 2.2 should break backwards compability, it's not our 
responsibility anymore!
