Scaffolding not working after restart of forge?

mzitg Jul 22, 2012 10:00 AM

My scaffolding works fine until i leave forge.

If i restart forge i get a IllegalStateException.

Has anybody seen this problem before?

I have tried Version 1.0.5.Final and forge-distribution-1.0.6-20120719.171604-23.zip.

Linux, JDK 1.7.0_05 Oracle

Hi Michael,

I have not seen this phenomenon (yet). Can you please post the (minimal) sequence of Forge commands that produces this exception so we can try and reproduce it?

Cheers,
Koen

mzitg Jul 23, 2012 4:40 AM (in response to koen.aers)

Thanks Koen

i did some research over night.

This is a verry simple example of a non-working forge-project: https://github.com/michzuerch/ScaffoldTest

These are my steps to create the project:

1. new-project --named ScaffoldTest
2. persistence setup --provider HIBERNATE --container JBOSS_AS7
3. scaffold setup --scaffoldType faces
4. entity --named Address
5. field string --named firstname
6. field string --named lastname
7. scaffold from-entity

Everything woks fine until i leave forge (exit).

After the restart i get this:

[ScaffoldTest] Address.java $ scaffold from-entity com.example.ScaffoldTest.model.Address.java
***INFO*** Using currently installed scaffold [faces]

Hi Michael,

This scenario seems to work fine on OSX Lion with Java 1.6.0_33. I'll try on a Linux box when I have one handy.

lincolnthree Jul 23, 2012 10:47 AM (in response to koen.aers)

Hi Michael,

This problem is caused because you are using wildcard imports in some of your sources and Forge cannot make accurated deductions about which types are on your classpath. You should be able to work around this problem by converting any wildcard imports to standard ones:

E.g. anything like:

import org.jboss.forge.*; --should become-> import org.jboss.forge.Shell; import org.jboss.forge.Blah;

Thanks,
Lincoln

koen.aers Jul 23, 2012 11:50 AM (in response to lincolnthree)

Ah then it means the Adress.java file was edited after exiting Forge and before relaunching it? Or else how can the wildcards appear in the source?

The stack trace makes sense when you explain it Lincoln, but it's not obvious at all what causes it without this inside knowledge. Forge should be able to tell what the problem in the sources is instead of just throwing this exception, no?

lincolnthree Jul 23, 2012 11:53 AM (in response to koen.aers)

Yeah, the error message could be a little more helpful. Typically wildcard imports show up when your IDE does auto-organization of imports when you save a file.

mzitg Jul 23, 2012 12:39 PM (in response to lincolnthree)

You are right Lincoln.

I changed the import from:

import javax.persistence.*;
import java.io.Serializable;

to

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Version;
import java.io.Serializable;

and now it works.

My IntelliJ did a 'optimize import'. You can change the settings with 'Settings, Codestyle, Java, Imports'.

Thanks,

Michael

rzd Feb 14, 2013 11:49 AM (in response to lincolnthree)

@Lincoln: Looking at the AbstractJavaSource class, the exceptions seems to indicate that this is an extension point, i.e. there is some work in progress to add support for wildcard imports. Could you provide a link?

Hi Rüdiger,

Yes, it is an extension point. We are currently discussing on the forge-dev@lists.jboss.org email list if you would like to join in. Send an email to the list with your request and I can include you

Thanks!
