Re: Announcement for the GWT 2.12 release

Fyi, gwt-maven-archetypes have been updated (version 2024.10.31) with GWT 2.12 (and Maven plugins each updated to their latest version)

Re: Error : No project found - Running GWT in client mode only

Hi Craig,

Just a heads up.
I finally managed to get all the files right. The package of the module responsible for generating the js file was war instead of gwt-app.
I changed this and referenced it as a war type in my main pom.xml file. Then I was able to get the no cache js files while running mvn package.

Now I have another challenge, I think it is for another topic. All my files are in the same war directory. I would like to have the html and css files in a separate folder from the generated js ones.
As I am running a standalone GWT app, and using the default GWT public path for static files, they all come under the same folder. I tried to use Maven WAR Plugin and copy-resources, but no luck.

Any ways, thanks

Hi craig thanks for your perspective.
Wildfly is going to be the server that is going to host the GWT compiled javascript/html etc. as I am going to use the errai framework.

When I run maven install, it does generate the war file and perfectly deploy to Wildfly (only with the index.html and css file. no js file). 
however I can't run gwt:devmode or gwt:codeserver. I have a project not found error and I don't have the "app.nocache.js" file generated either.
My guess is I am not doing something right with my gwt-maven-plugin configuration plugin, either on my client pom.xml file or my main project.xml file.

Any advice?

Which server is going to host the GWT compiled JavaScript / HTML / ...?
1. If you'll have your own server, just leave the architecture as is, and write your calls to the external server in the the client.
2. If you need to host it on the external server, again, just leave the  architecture as is, as you can just copy the compiled GWT code across when you are ready to deploy.  But, if this is the situation, it's a bit crazy to not just make the external server a GWT app.

The GWT project is generated with the Tbroyer archetypes modular web-app.
This is what I did so far :
- copied the webapp folder from the web-project-server/src/main to web-project-client/src/main
- deleted the web-project-server and web-project-shared folders.
- updated the web-project-client's packaging from gwt-app to war
- kept the main pom packaging to "pom" because, soon the client's project is going to  have another modules(maven).
- deleted all reference to the two modules in the main pom.xml file.

So, if I run mvn clean install I can see that a war file is generated that can be deployed let's say to a Jboss/ wildfly server app.

However, from the main folder where the main pom.xml file is, I have an error of No project found if I run mvn gwt:codeserver -pl *-client -am

is there any other tweak I should consider on both poms xml file?
Notice that, if the packaging is kept to gwt-app in the client module, codeserver/devmode runs without a problem but I will have no reference the webapp files (index.html, css) because they won't be referenced.

Please advise.

Add {} around the switch. This will fix the issue.
