Incomplete import in Java generated code by Papyrus Designer [message #1843871]

I have a UML model in Papyrus with a set of signals within a package. These signals are organized into a hierarchy.

When I generate code, what I get for the signal at the root of the tree is correct, as below:

package com.elastskin.ppmweb.service.state.productionsignals.Signals;
public abstract class Prod_Signal {
/**
*
*/
public Instant pevttimestamp;
}

but the code for all descendants contains a line with an ill-formed import (missing the '*' at the end):

package com.elastskin.ppmweb.service.state.productionsignals.Signals;
import com.elastskin.ppmweb.;
public abstract class Prod_PrintSystem_Signal extends Prod_Signal
{
}

Is it a bug? How can I work around it?

Hi

I suspect that you are looking in the wrong direction. The Eclipse tooling that I use does not usually use "*" imports; rather all required imports are provided explicitly. If a "*" appears it comes from the Java prettifier. Perhaps the target of a missing import is not accessible.

Thanks for your response, Ed.

When you say "Eclipse tool" do you mean a Java IDE or Eclipse Papyrus? My problem is with the Papyrus code generator and not with the Java IDE.

I was expecting Papyrus to generate the explicit imports for each dependency, as you said, but that is not what is happening.

Hi

I'm mostly referring to EMF and my own OCL CG based on EMF. When I don't like what I see I go in with a debugger and as often as not discover that the problem is my inadequate configuration, perhaps based on the need to use a poorly documented facility. Sometimes it is necessary to create a tool customization that may perhaps need contributing back a s a fix.

I've just found out that in a previous version of my Papyrus project, this problem does not happen and Papyrus generates all Java imports beautifully.

I am trying to figure out what have I changed in the project that causes the problem.

If I find it might be a bug, I will report it to the appropriate channel. Going further than that is beyond my possibilities because I don´t have the expertise and time to venture into changing Eclipse.

Thanks for your comments, Ed.
