Re: Converging efforts for Maven Plugin (tbroyer) and GWT Plugin (Eclipse)

Thanks Thomas.  That makes sense.  Good to get some more knowledge about the plugin (which is fantastic btw.  If it didn't exist, I would be in a lot of trouble, so thank you for creating it!).

And yes, I'm definately in the 95% not proficient with Maven.  😁

If you're not proficient with Maven (like 95% of its users), mostly poking at it until things work (nobody will blame you, documentation is really lacking), I admit it can certainly be. Maven's design is broken in many ways (Maven 4 goes into the right direction, but it's been years in the making and still not there yet) but it has much more to offer than how most people (try to) use it.

 

Right now, my top level pom has "<packaging>pom</packaging>".  My client module has "<packaging>gwt-app</packaging>".  And my server module has "<packaging>war</packaging>".  Why is the client packaging called "gwt-app", why not just called it "war" like the server.

Because it's not a WAR per se, it's just some ZIP archive that contains the output of the GWT compilation. The only reason the output file is named .war rather than .zip is such that it can easily be used as an "overlay" by a the maven-war-plugin (technically it could be a ZIP, but the maven-war-plugin requires them to be declared in the plugin configuration, which means there's no dependency from the server to the client, so Maven doesn't know that it has to build the client before the server). IIRC, this also was before "webjars" were widely supported (and a few years before Spring Boot); and webjars have other issues: you don't want any of the dependencies from your "client" POM to be resolved when depending on it from the "server" module, which a war gives you "for free": https://maven.apache.org/ref/3.9.9/maven-core/artifact-handlers.html

But as Elias said, the "packaging" in a Maven POM opts in to a build "lifecycle", and this actually is the only reason for that <packaging>gwt-app</packaging>: https://tbroyer.github.io/gwt-maven-plugin/lifecycles.html / https://maven.apache.org/ref/3.9.9/maven-core/default-bindings.html

In other words, this is just how Maven works.

 

And why does it need to know how the server will be packaged at all,

It doesn't (nowhere in the plugin will you see it look at the server module and/or how it's packaged). You're free to use the produced .war archive the way you want. Use the maven-resources-plugin to extract its content if you prefer, it's not a real WAR, it's just a ZIP archive with a .war name, due to Maven's way of resolving things and other limitations.

Re: Converging efforts for Maven Plugin (tbroyer) and GWT Plugin (Eclipse)

"Thomas Broyer", I am afraid only GWT Eclipse Plugin can do what my projects require, anything else involves additional effort, introducing possible complications.

Hence my original thought about convergence of efforts, so that the Maven Plugin and the GWT Eclipse Plugin can keep working together.

Re: Converging efforts for Maven Plugin (tbroyer) and GWT Plugin (Eclipse)

I think it all has to do with the new lifecycle introduced by the new Maven plugin.

I am personally not using the new packaging, keeping the runnable module with "war" packaging, all other modules with "jar" packaging and forcing execution of the GWT compilation goal for use as overlay in a downstream module with a "war" packaging.

This satisfies the requirements of my projects which rely on use of overlays in downstream modules with a "war" packaging.

Other projects could be having different requirements for which the Maven plugins new lifecycle could be suitable.

Re: Converging efforts for Maven Plugin (tbroyer) and GWT Plugin (Eclipse)

Good points.

Now you're trying to migrate to the net.ltgt.gwt.maven plugin, and doing so the Eclipse integration no longer works?

Actually the Eclipse integration seems to be working well so far,  just with standard packaging , not the special packaging options offered by the new Maven Plugin.

It seems I have probably misused the Maven plugin by trying to assign "gwt-app" packaging to the runnable module.

 

The only way I've ever used GWT+Maven within Eclipse (more than a decade ago) was only through M2E, using Run As… → Maven Build… to run the gwt:codeserver goal

I am actually creating Eclipse run configurations of "GWT Development Mode (DevMode)" type, with built-in server port and "Super Development Mode" option which is quite similar to your approach but without separate steps for "codeserver" and application startup.

This is required to keep the running steps as uniform and simple as possible for the members of my teams, a single and easy to create Eclipse run configuration for each GWT app.

I don't think we can talk about a "convergence" then.

It is possible that nothing more is needed, but I would like to hear people's theories.

how are you trying to migrate the projects? Refactor them to make them follow the expected structure...

It seems initially I only have to replace the old Maven Plugin with the new one, which is actually better than its predecessors because it is not tied to a specific version, making my transformation smoother.

In the second stage I intend to switch to GWT 2.12.x from 2.9.0 (or earlier)

In the third stage, after Jetty gets decoupled from GWT,  I intend to start making efficient use of my "GWT-DevMode-server" project, as discussed in a separate topic.

Have you tried with a project generated from the various available archetypes? (either mine, or NaluKit's using Spring Boot) How does the developer experience in Eclipse look like?

I haven't done this for the solutions I am transforming in fear of increasing the transformation effort, but I will happily consider the option for new solutions.

It is worth mentioning that the situation I am referring to is only a very small part of a wider effort to transform a large number of enterprise GWT apps that are currently using GWT 2.9.0 and the matching Maven plugin and getting it right the first time matters.

Converging efforts for Maven Plugin (tbroyer) and GWT Plugin (Eclipse)

Driven by https://github.com/tbroyer/gwt-maven-plugin/issues/176

I discovered a situation where a Maven structure well understood by GWT Plugin does not seem to be working well in relation to the current Maven plugin (tbroyer) , or vice versa.

Not knowing the answer and given that the components are working together, consuming each other's output, I believe Maven plugin and GWT Plugin efforts should be converging, as it seems they had been in the past.

It is worth mentioning that the situation I am referring to is only a very small part of a wider effort to transform a large number of enterprise GWT apps that are currently using GWT 2.9.0 and the matching Maven plugin and getting it right the first time matters.

Please share your thoughts.

Re: Compatibility of GWT 2.10.0 with GXT 2.3.1.a

I guess it's tricky - GXT is still owned by Sencha, even though I don't believe they actively sell it these days. My firm was one of the early customers, and we still pay Sencha for maintenance. TBH, there's nothing much in the way of enhancements going on and we always have to prod them when we find issues with newer versions of GWT (sometimes even sending them the mods we find our side). But they have come through with fixes and changes we needed. This thread here describes one of those cases - we're now on GWT 2.12.0 and GXT 4.2.0 and it's all working fine together, but we did have to push Sencha to get mods done for this specific case and issue a new GXT release for that.

FWIW - a few of our panels still use the older GWT-Ext widget set which later became part of SmartGWT. We've had no issues with those in GWT upgrades, although of course no one maintains them so it is very much "fix it yourself". It's also non -trivial making GXT and GWT-Ext live side by side in one app due to overlaps in the CSS style names. We had to create a manual munging script to sort that out, but the effort of that was lower than recoding all of those panels - we replace them slowly over time as we need.
