Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Brandon Donnelson]

It appears that the  org.ow2.asm:asm-parent:pom:5.0.3 @ is fixed after 
upgrading to maven 3.2.3. The pom issue goes away.

[Colin Alworth]

Looks like codehaus's snapshot repo is down, so I'm unable to get the 
latest gwt-maven-plugin. This url gives a 504 gateway timeout from ngnix 
for me:
https://nexus.codehaus.org/content/groups/snapshots-group/org/codehaus/mojo/gwt-maven-plugin/2.7.0-SNAPSHOT/maven-metadata.xml

If I set gwt-user and gwt-servlet to 2.7.0-SNAPSHOT and gwt-maven-plugin to 
2.6.1, I get the NoClassDefFoundError:

All GWT copies on the classpath are 2.7.0-SNAPSHOT, its just building under 
gwt-m-p 2.6.1. 

Is this really expected? I'm probably misunderstanding how scope=import 
works and its importance (ha) to the build, but the strong implication 
seems to be that gwt-m-p is pulling in gwt-dev, but not transitive 
dependencies.

Pre-send edit: codehaus is back, pulling down results now. As with others, 
I am getting that org.ow2.asm:asm-parent:pom:5.0.3 is inexplicably missing, 
even if I delete it from my .m2/repository and the build *downloads* it, it 
claims it can't find it. Full gist from debug log: 
https://gist.github.com/niloc132/da63de6d8e8da90f49d7

Is there any chance that this is a 'feature' of scope=import, that you have 
to pull content from the same repos that the import'd pom came from, and 
that you can't get it from even the other defaults?

For reference sake, the project I'm building is 
https://github.com/niloc132/gwt-rpq on the 2.7.0 branch - first build rpq 
itself (gwt vers doesnt matter), then build gwt-rpq. Maven version included 
in the gist above.

Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Brandon Donnelson]

I found the reason, trying to find a workaround.

The repository definition is causing it to try to download from snapshots 
where it doesn't exist.

I'm' also having some trouble. I get errors related to both requestfactory 
and asm-parent.
You can see the error message and pom.xml at this gist: 
https://gist.github.com/tskardal/0d8287da4265c0fddfc8

I've created a project using the maven archetype, modified the versions and 
added the snapshot repos.

Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Ümit Seren]

Ok this error has nothing to do with GWT but with Errai. They iterate
through the current working directory (CWD) to find the output folder to
generate the server side marshalling classes. If the CWD has symbolic links
this will apparently result in a NullPointerException. I have the strong
feeling this is a bug (it should have a nullpointercheck).

 gwt-maven-plugin snapshots are deployed to codehaus, but the plugin
 depends on GWT snapshots which are at sonatype, and Maven thus uses the
 pluginRepositories to download them as dependencies of the gwt-maven-plugin
 (it doesn't look like it uses the repositories listed in gwt-maven-plugin's
 own POM).

 Does it change anything if you declare google-snapshots as a
 pluginRepository as well?

Somehow I made the requestfactory error go away but I'm still getting this 
one:

 Does it change anything if you declare google-snapshots as a

Assuming you're using a 2.7.0-SNAPSHOT, you'd have better luck on the

Well, RF is good at RPC too (using ValueProxy).
I think Google is using it mostly that way, with the JSON-RPC dialect (I 
don't think they use the "native" dialect, that allows batching, etc.).

However there are also some pain points: For example on the server side it

I was thinking about generating code for the server (or JVM clients), but 
the current use of ServiceLayers is likely to greatly limit the gains in 
performance…
Still, walking the object hierarchies might benefit from such codegen.

Though less strong that with GWT-RPC, because the client and server have to 
use "compatible" versions of the proxies (compatible in a way similar to 
how ProtoBufs are compatible with one another), not necessarily the exact 
same class as in GWT-RPC (well, there are solutions I believe for GWT-RPC, 
by having several serialization policies at once on the server).

Well, RF has a well-defined (though not well-documented) protocol, and it's 
capable of using JSON-RPC (though only on client-side), so you *could* use 
a single endpoint.
But I otherwise agree with your point.

Re: RPC vs. RequestFactory vs. RestyGWT

[Ümit Seren]

I have been using RequestFactory extensively for a project and I must say 
that although it is pretty well engineered, the learning curve is quite 
high. 
If you have a CRUD heacy application where you send and receive lots of 
data, it might be a good solution (because it only sends deltas). 
However there are also some pain points: For example on the server side it 
uses Reflection to initialize the server instances which is slower than if 
the code would be generated. 
Also currently there is no real further development ongoing (apart from 
some bugfixes). 

Another downside is that there is really strong coupling between backend 
and frontend with RF. 
In many cases you might need a public API to access the data from non GWT 
clients, so you might end up implementing two endpoints (RF and REST). 
If I would start again I probably would choose REST over RF just because it 
clearly separates frontend from backend.

Re: RPC vs. RequestFactory vs. RestyGWT

[Vassilis Virvilis]

I am using RestyGWT although I am still using it in a RPC type of way and
not in a RESTful way.

The main reason is that I can split the project to server part and client
part more easily. The server part goes with all of my other services
without gwt jars where it can share code etc...

Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Ümit Seren]

Hmm that's weird. I remember that when I tried to compile the same app with
2.7.0-SNAPSHOT (gwt-maven plugin) two weeks ago it worked fine with maven
3.0.5.

However I have now a different issue:

I have used your gwt archetype (
https://github.com/tbroyer/gwt-maven-archetypes)  and I have three modules
(app-client, app-server and app-shared) inside a parent pom project (app) .

When I run "mvn clean install" in app-client everything works fine (gwt
compiles, finishes).
However when I run "mvn clean install" in parent "app" pom projet I get
following error:

Multiple cell Renderers (or composite cells with UiRenderer/UiHandler)

[Shaun Tarves]

I have a fairly complex question about using cells with UiRenderer. I'm 
finding that for the same object type, I have several variations of the 
cell that I render based on the view and context it's rendered in. For 
example, sometimes the cell has a button to remove/delete, other times it 
doesn't. Sometimes, I want to wrap text in anchor tags, other times I want 
them to just be spans. 95% of the cell rendering template is the same in 
these cases.

This creates (mostly) duplicative renderer code and xml, so I am looking 
for a better solution. My thought was to have a master renderer with some 
elements that would contain the rendered SafeHtml of smaller partial 
renderers.

I have seen that I can use a SafeHtml template to render a portion of the 
html for the cell renderer, but I would lose the ability to have UiHandlers 
on those elements created as just SafeHtml from the Template (which is 
really handy).

Is there a way to make this work? Can I delegate browser events to "sub" 
renderers? Is this better approach here?

I suppose what I'm asking for might be UiRenderer-based composite cells, 
but I've seen no examples of how to do this.

no it didn't help unfortunately.
But I upgraded to maven 3.2.1 and the error went away.

 I have tried adding gwt-dev, gwt-codeserver, and the asm dependency but

 I'm still a bit green when it comes to maven.

Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Thomas Broyer]

gwt-maven-plugin snapshots are deployed to codehaus, but the plugin depends
on GWT snapshots which are at sonatype, and Maven thus uses the
pluginRepositories to download them as dependencies of the gwt-maven-plugin
(it doesn't look like it uses the repositories listed in gwt-maven-plugin's
own POM).

Does it change anything if you declare google-snapshots as a
pluginRepository as well?

This is how the repositories look like



codehaus-snapshots
https://nexus.codehaus.org/content/groups/snapshots-group/


false


true







google-snapshots

https://oss.sonatype.org/content/repositories/google-snapshots/

true


false





When I checked the 
https://gwt.googlesource.com/gwt/+/master/samples/dynatablerf/pom.xml 
sample it had also the  
https://oss.sonatype.org/content/repositories/google-snapshots/ as a 
pluginRepository ? 

Where do you deploy the latest gwt-maven snapshot to sonatype or codehaus ?

I'm using Eclipse Kepler with m2e 1.4.0.2xx. I think my maven version is 
3.0.4 - it's the one that came embedded with eclipse. I'll try the new 
eclipse and see what that says.

RPC vs. RequestFactory vs. RestyGWT

[Ralf Klemmer]

I've used RPC, RequestFactory and now RestyGWT in some GWT projects.
In my opinion RequestFactory development should be canceled and replaced by 
RestyGWT (or something like that).
My key arguments for that drastic opinion:

RPC
+ easy to learn
- proprietary
- problems when trying to send hierarchical entities over the wire
- mostly leads to DTOs, which leads to boilerplate code for mapping DTOs 
and entities, which leads to hardly maintainable code if you have to deal 
with hierarchical objects (e.g. entity A contains entity B which contains 
list of entity C)

RequestFactory
- proprietary
- high learning curve
- bad documentation (almost every is very old)
- development is slow (compared to other techniques)
-  boilerplate code
+ "standard" GWT communication
+ integration with Editor framework
+ transfer of data delta between client and server

RestyGWT

indeed "option 2" of the post solves the problem.

Which version of Maven are you using? Also, have you configured the
google-snapshots both as a repository *and* pluginRepository? (I think this
is needed for the plugin to resolve its dependencies)

I was fighting yesterday with a discrepancy between Maven 3.0.5 and 3.1 /
3.2 with the maven-invoker-plugin (used to run tests of the
gwt-maven-plugin): things passed with 3.1 (on BuildHive) and 3.2 (on
Travis-CI) but failed on my machine (3.0.5). Trying with 3.2.3 on my
machine, things worked. The error was exactly the same wrt
com.google.web.bindery:requestfactory.

The error about ASM is strange though, it's in Central so it should Just
Work™, unless you have some repository/mirror configuration getting in the
way?

I think I'm getting two errors relating to the bugs in the POM that Thomas 
mentions above:

I have tried adding gwt-dev, gwt-codeserver, and the asm dependency but 
still getting it. Also tried forcing an update of snapshots/releases but no 
change.

I'm still a bit green when it comes to maven.

Devmode (the classic one) using trunk

[Alberto Mancini]

Hi, 
doing some test using the last trunk I got this error trying to start 
devmode. 

I think it is not really something important cause we are 'leaving' devmode 
but 
at least something to notice.

Alberto.
