relaunched mvn gwt:debug ... works as a charm

Sylvain

Hello Alex,

Just wanted to say that you are not the only one. My Chrome upgraded itself this morning and now the Dev Mode stopped working. I'm working through this issue as well.

Kind regards,
Mike

This just suddenly started happening to me. I'm developing using the Maven gwt plugin on OS X against Google Chrome. I've been using it for many months with no problem. Now I get prompted to download the plugin again with the message:

But I already have it installed. I've tried removing it and re-installing but I still get this message.

Any help would be greatly appreciated!

Thanks,

Re: Running new auto compile super dev mode from maven plugin

Did you list all module sources in the build-helper-maven-plugin in the module you run gwt:run in?

This is an unfortunate but necessary hack to get things working.

Hi Thomas,

I tested "compile on refresh" (CoR) with your archetypes, and it works fine (using mvn gwt:run).

However, CoR does not work in my project (gwt 2.7, using mvn gwt:run).

File changes don't seem to be picked up by SDM:

[INFO] GET /recompile/App
[INFO] Job com.myproject.App_1_4
[INFO] starting job: com.myproject.App_1_4
[INFO] binding: user.agent=safari
[INFO] skipped compile because no input files have changed
[INFO] 0.038s total -- Compile completed

I have a particular maven structure where I have a root GWT module that aggregates a dozen of other GWT modules.
The parent GWT module is in its own Maven module, and all child GWT modules are in separate Maven modules.
The parent Maven module contains 0 java code. All java code is located in the child Maven modules

/
├── app (Maven module, contains 1 gwt module inheriting all child GWT modules, no Java code here)
├── module1 (Maven module, pom)
│ ├── client (Maven module, contains 1 GWT module + Java files)
│ ├── server
├── module2 (Maven module, pom)
│ ├── client (Maven module, contains 1 GWT module + Java files)
│ ├── server
├── module3 (Maven module, pom)
│ ├── client (Maven module, contains 1 GWT module + Java files)
│ ├── server

I tried changing UiBinder files, View or Presenter files (using GWTP here), no changes are ever picked up.

Any hints?

Hi all...

So I'm trying out gwt 2.7-rc1

I'm using the same maven config as I had for 2.6

I precompile all my sources so when I start the app it picks up the gwt module.

When I run the app for the first time it correctly says "compiling" (as it doesn't precompile) and once done the app loads.

But after that when I refresh it doesn't pick up that there are changes and recompiles...

I have to do a full recompile to pick up the changes.

Re: Chrome GWT Plugin required but is already installed

Thank you Jens. This would explain it.

I can't find any way to downgrade Google Chrome on my mac. I don't appear to have a Google Software Update app as some webpage suggested I should.

GWT 2.7.0 won't compile my application (2.6.1 has no problem). The error message is so cryptic there's no hope to figure out why.

I've tried for 3 hrs now to get Super Dev Mode to work but the documentation is terrible so I can't figure it out. I'm hoping you can help with that since I'm out of options.

I can't understand the GWT documentation on running SuperDevMode. It says:

If you are not using Dev Mode, first you need to compile the GWT application and launch a web server that serves its output files.

I don't know what that means. Are they suggesting that I simply create a standard war file and deploy that on a web server like Tomcat?

The instructions on running the code-server are also lacking details. I've no idea how to launch this codeserver or set up my classpaths. I've tried using the maven gwt:run-codeserver goal and it does a bunch of compilation and looks to launch a server but when I visit the URL I get this error in my browser:

Latest Chrome on Mac OS is now 64bit but the browser plugin is only 32bit so it does not work anymore.

You can:
- downgrade your Chrome to version 38 and turn off auto update
- use Firefox 24 ESR or 26 (GWT plugin does not work in newer versions of Firefox)
- instead of DevMode use SuperDevMode which does not require any browser plugins.

Re: REST Service on Backend which Framework in GWT?

But my question was more in frontend direction using REST in GWT:
E.g what is the difference between REST support in gwtresty and gwtquery project. Which one should I give a try?

Take a look at both documentations and choose the one you feel comfortable with?

Re: REST Service on Backend which Framework in GWT?

Thank you. Dropwizard looks quite interesting and I think I could give it a try. Only the micro service conzept could be problematic. My applicatoin is big and I am not sure if I want to split it up in different backend projects....

But my question was more in frontend direction using REST in GWT:
E.g what is the difference between REST support in gwtresty and gwtquery project. Which one should I give a try?
