Wiered "[ERROR] Errors in 'jar:file..." "cannot be resolved to a type"

[Zied Hamdi]

Hi,

I have a series of interdependent GWT projects, all the chain works fine, but the last element seems to be unable to read java classes from the generated jar : I checked the jar, the .java and .class files are really there where they are supposed to be : it's amazing that the compiler finds the jar containing the wanted class but it doesn't read it (this is the case for many classes, see the pf file)

 [ERROR] Errors in 'jar:file:/C:/Users/Zied%20Hamdi/git/VuMe/ShopAdmin/build/libs/ShopAdmin-1.0.jar!/fr/onevu/vume/shopadmin/ShopAdmin.java'
            [ERROR] fr.onevu.vume.shopadmin.ShopAdminClientFactory cannot be resolved to a type

The project ShopAdmin is the first in the chain to have a src/main/java structure (all other projects are eclipse projects converted to gradle without changing the tree sutrcture). this might be a hint to understand the cause of the issue...

}

but the generated jar file has everything in place : the uncompresses jar contains the class there where it is supposed to be :

Any ideas?

Ok!

That was my fault, I didn't have to resolve dependencies manually for a while. It was just a classpath problem (of a jar added manually because it's not available on maven)

I just had to follow the unresolved symbols causes chain until I found the dependency on // https://mvnrepository.com/artifact/com.google.gwt.google-apis/gwt-ajaxloader

compile group: 'com.google.gwt.google-apis', name: 'gwt-ajaxloader', version: '1.1.0' was not added

Sorry, this wasn't very useful in the forum (it's typically a beginner problem, but since gradle compiling and GWT 2.7 are new to me, I forgot my basics)
