Mvp4g have dependency gwt-servlet 2.7.0. May be this the source of problem ?

[Frank Hossfeld]

I don't think that this problem is related to mvp4g. It looks like you upgraded your project to GWT 2.8.0 and have some old stuff in your classpath.

Take a look here: https://groups.google.com/forum/#!topic/google-web-toolkit/9kuaxBeIx0k

Hope that helps.

 I see in Eclipse project folder "Project and External Dependencies" gwt-servlet-2.7.0.

So if i declare exact dependency on gwt-servlet-2.8.0 with 

compile group: 'com.google.gwt', name: 'gwt-servlet', version: '2.8.0'

other error occurs:

I've managed to avoid internal compiler errors by redefining dependency on mvpg in gradle script via file:

compile files('libs/mvp4g-1.5.2.jar','libs/gin-2.1.2.jar')

So I think this is gradle dependency conflict. I'm no so strong in gradle may be someone explain this strange gradle stuffs.

[Frank Hossfeld]

Using mvp4g 1.5.2 with GWT 2.8.0 in a Maven works without problems. I would expect that it will work wituout problems using Gradle.

How did you set up mvp4g in your Gradle project as the error occured?

[Олег Рачаев]

plugins {

  id "fr.putnami.gwt" version "0.4.0"

}

group = 'nipi.raz4rn'

version = '0.1'

apply plugin: 'java'

apply plugin: 'eclipse'

apply plugin: 'fr.putnami.gwt'

apply plugin: 'maven-publish'

repositories {

mavenLocal()

    mavenCentral()

}

dependencies {

compile group: "nipi.gwt.login", name: "nipi-gwt-login", version: "+"

compile group: "nipi.ois.model", name: "nipi-ois-model", version: "+"

The above code is build.gradle. I am using Gradle 3.5.

I think the problem comes from gwt-servlet 2.7.0. And if to tell more precisely because of the version of gwt-servlet that comes.

The compliler error says:

java.lang.NoSuchMethodError: com.google.gwt.util.tools.shared.Md5Utils.getMd5Digest

And as I see: 

com.google.gwt.util.tools.shared.Md5Utils.getMd5Digest 

is in gwt-servlet 2.7.0.

[Олег Рачаев]

I continued my research and found a solution.

The solution is to add 2 lines to dependencies of build.gradle

compile group: 'com.google.gwt', name: 'gwt-servlet', version: '2.8.0'

compile group: 'org.ow2.asm', name: 'asm', version: '5.0.3'

Then as I came to this:

I looked at the dependency tree and found:

+--- com.googlecode.mvp4g:mvp4g:1.5.2

|    +--- com.google.gwt:gwt-servlet:2.7.0 -> 2.8.0

|    \--- com.google.gwt.inject:gin:2.1.2

[Frank Hossfeld]

Looking at your gradle.build (the first one you posted), you did not specify the compile group for GWT, so Gradle uses the one from the pom of mvp4g. In this case you have to GWTversion in your build path.

By adding:

compile group: 'com.google.gwt', name: 'gwt-servlet', version: '2.8.0'

the GWT 2.7.0 version gets overwritten. 

I would change:

compile group: 'com.google.gwt', name: 'gwt-servlet', version: '2.8.0'

to

compile group: 'com.google.gwt', name: 'gwt-user', version: '2.8.0'

to avoid more class path issues. 

[Олег Рачаев]

Ok. I've changed script. But without

compile group: 'org.ow2.asm', name: 'asm', version: '5.0.3'

compiler errors are still present.

That's possible, because this is a dependency of Guice.

I found similar problems discussed here:

May be this helps someone.
