[gwt-contrib] Re: GWT + Maven - Using gwt-dev package as dependency

2014-02-10 Thread Gilberto Torrezan Filho
Thank you Thomas and Colin for your replies.

Thomas, sorry for posting in the wrong place. I didn't even know there is a 
gwt-maven-plugin users group... thanks for pointing that out!

Working with separated projects with GWT, Maven, Eclipse (and his friends - 
the plugins!) and App Engine is really hard and sometimes frustrating... 
but when it works is really useful, mainly for environments with continuous 
integration. All hail to The Maven Way™!

 idea, and violates The Maven Way™, so in practice gwt-dev should 
 effectively not be a problem. FWIW, I do believe that warning should be 
 removed. 

 Also, BTW, you should have rather posted to the gwt-maven-plugin users 
 group, or the GWT users group.

[gwt-contrib] Re: GWT + Maven - Using gwt-dev package as dependency

2014-02-07 Thread Colin Alworth
If you know enough to start writing generators, it almost certainly is not 
a concern - you are probably also careful with which GWT version you are 
using as well as which gwt-m-p version. A problem can occur if more than 
one version of gwt-dev is present on the classpath, such as a mistakenly 
declared copy in your dependencies and the copy that gwt-m-p automatically 
pulls in. Provided both versions are the same or care is taken to ensure 
that gwt-m-p uses the same dependency, there is no issue.

See 
http://mojo.codehaus.org/gwt-maven-plugin/user-guide/using-different-gwt-sdk-version.html
 
for how to configure your project to allow for different GWT SDK version 
from the maven plugin. I typically use two different properties, one for 
gwt.version, and a second for gwt.plugin.version with this strategy to 
allow them fall out of sync in a safe way.

 Hi,

 I'm using GWT 2.6.0 with Maven, using the gwt-maven-plugin, and in my 
 project I have some auto generated classes (using the generated-with 
 directive on Module.gwt.xml). The generator is a subclass of 
 com.google.gwt.core.ext.Generator.

 The problem is: every time I build my project, Maven emits a warning:

 [WARNING] Don't declare gwt-dev as a project dependency. This may 
 introduce complex dependency conflicts


 ... but I have to declare gwt-dev as dependency, since I need it to 
 compile my code generator.

 I never faced any conflict - maybe because I'm declaring gwt-dev with the 
 provided scope, avoiding it to be part of the generated war. So, in this 
 scenario, is that warning still accurate? Is there any other way to avoid 
 it (while still having the code generators)?

 Thanks.
