I have a DSL working ok when I test with
I want to incorporate int main eclipse.
I go into "Deployable plug-ins and fragments", select all plug-ins (rpc, rpc.tests & rpc.ui) and then "Install into host,
Repository."
Operation fails:
=========================================
Problem during export
Errors occurred during the export operation. The ant tasks generated log files
which can e found at /srv/devel/install/logs.zip
=========================================
I do attach the complete zip file, but errors are all the same:
=========================================
1. ERROR in /srv/devel/parser.WS/com.softin.rpc/src/com/softin/rpc/MyIntegerConverterImplementation.java (at line 10)
public Integer toValue(String string, INode node)
throws ValueConverterException {
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The method toValue(String, INode) of type MyIntegerConverterImplementation must override a superclass method
=========================================
Which is strange.
MyIntegerConverterImplementation.java is trivial:
=========================================
package com.softin.rpc;
import org.eclipse.xtext.conversion.IValueConverter;
import org.eclipse.xtext.conversion.ValueConverterException;
import org.eclipse.xtext.nodemodel.INode;
public class MyIntegerConverterImplementation implements IValueConverter<Integer> {
@Override
public Integer toValue(String string, INode node)
throws ValueConverterException {
return Integer.decode(string);
}
@Override
public String toString(Integer value) throws ValueConverterException {
return value.toString();
}
}
=========================================
I also tried commenting out the offending "@Override" and the export seems to succeed, but the same errors pops up again when the editor is actually instantiated.
What am I doing wrong?

Hi Mauro,
it looks like your export uses another compatibility level for the Java
compiler, e.g. 1.5 vs 1.6. Unfortunately I don't know why this could happen.

Thanks for the answers.
Unfortunately I still need some help
(please see the LAST error listing).

It may have happened because I created the workspace (containing a single xtext project rpc, rpc.tests and rpc.ui) on one machine (Win7-SunJava_1.7) and then I moved it to another one (ubuntu_11.04/OpenJDK_1.6) and proceeded to continue development there.

Unfortunately this doesn't appear to be true.
I proceeded to correct the error (I now have "JavaSE-1.6" consistently everywhere, but I had to manually edit several files), to regenerate the project (cleaning it and then re-running GenerateSIDL.mwe2).

=======================================
I see nothing wrong here.
This leads to a working executable if I run "Launch Runtime Eclipse" (as before!).
When I run the "Export Wizard" (checked rpc & rpc.ui; Install into host. Repository.; pointer to empty dir) I only get the expected "You will need to restart Eclipse..." message (I select "Restart Now").
Everything seems ok, but if I open an example file for my SDL I get: "could not open the editor: An unexpected exception was thrown.";

Hi,
I still need to solve this.
Can someone help, please?

I keep getting the same kind of message as Mauro when trying to open my editor after having installed the plugin:
org.eclipse.xtext.parser.ParseException: java.lang.Error: Unresolved compilation problem:
The method toValue(String, INode) of type DOUBLEValueConverter must override a superclass method
DOUBLEValueConverter is my value converter class for decimal literals:
package it.unibo.xtext.myvalueconv;
import org.eclipse.xtext.conversion.ValueConverterException;
import org.eclipse.xtext.conversion.impl.AbstractLexerBasedConverter;
import org.eclipse.xtext.nodemodel.INode;
public class DOUBLEValueConverter extends AbstractLexerBasedConverter<Double> {
public DOUBLEValueConverter() {
super();
}
@Override
public Double toValue(String string, INode node)
throws ValueConverterException {
if (string == null)
return null;
try {
return Double.parseDouble(string);
}catch (NumberFormatException e){
throw new ValueConverterException(e.getMessage(), node, e);
}
}
}
How come the message says that I should override the method that I overrode? Is it because of generics?
The bundles were configured for J2SE 1.5, but switching to 1.6 and rebuilding everything didn't do the trick.
Any suggestions?
EDIT: I keep getting the same error even removing the @Override annotation from the "toValue" method...

I think it's because toValue comes from the interface IValueConverter
thus it is an abstract method and Java 5 does not accept @Override
annotation for abstract methods...
you should make sure to set the compiler settings in your workspace to
use J2SE 1.5 so that you are notified about these errors in your
developer workspace so that you can fix them and export the plugins
again and reinstall them...
hope this helps

mh... you mean you removed the @Override from
public class DOUBLEValueConverter extends
AbstractLexerBasedConverter<Double> {
public DOUBLEValueConverter() {
super();
}
@Override
public Double toValue(String string, INode node)
and you still get this error
org.eclipse.xtext.parser.ParseException: java.lang.Error: Unresolved
compilation problem: The method toValue(String, INode) of type
DOUBLEValueConverter must override a superclass method
that makes no sense :)
it means it's still using the old code
