Java Extension [message #526568]

I want to call a JAVA method from my Xtend file.

In my Xpand file, it's called like this :

Quote:

package «package(this.name)»;

In Xtend, I defined this extension :

Quote:

Void package (String s) :
JAVA specific.Package.Name(java.lang.String);

And my JAVA file is that :

Quote:

package specific;

public class Package {
public final static void Name(String name){
System.out.println("mypackage"+name);
}
}

But when I run the workflow, I get

Quote:

package ;

What do I need to modify ?

hi,

Quote:

package ;

is actually that what you tell the gerneator to produce in your template

package <<nothing>>; => package ;

what is your expected result?

Hi again,

if you want to let the java extension calculate your package name your should modify your code like this

String package (String s) :
JAVA specific.Package.Name(java.lang.String);

package specific;

public class Package {
public final static String Name(String name){ 
 return "mypackage"+name;
}
}

Hello Maxime,

thank you very much for your question. This feature is not good described in the Xpand documentation. I will update this part of the documentation.
Please try:

public class Package {
public final static String Name(String name){
return ("mypackage"+name);
}
}

You have forgot to specify the return.
The System.out.println inside the documentation is for logging to the console but does no generator output.

Regards
Darius

expected resultat was
package mypackageName;

Your solution is indeed working, thank you.
