Hi all,

when starting the generator using the new versions of MWE and Xtend the
console log gets filled up with stacktraces of java.io.FileNotFoundException
for each generated file.
Looking like this:

9359 [main] ERROR esource.generic.XMLEncodingProvider  - Error detecting 
encoding for file:/home/.../some/file
java.io.FileNotFoundException: /home/.../some/file (No such file or 
directory)
	at java.io.FileInputStream.open(Native Method)
	at java.io.FileInputStream.<init>(FileInputStream.java:137)
	at 
org.eclipse.emf.ecore.resource.impl.FileURIHandlerImpl.createInputStream(FileURIHandlerImpl.java:99)
	at 
org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterImpl.createInputStream(ExtensibleURIConverterImpl.java:354)
	at 
org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterImpl.createInputStream(ExtensibleURIConverterImpl.java:348)
	at 
org.eclipse.xtext.resource.generic.XMLEncodingProvider.getEncoding(XMLEncodingProvider.java:32)
	at 
org.eclipse.xtext.generator.JavaIoFileSystemAccess.getEncoding(JavaIoFileSystemAccess.java:140)
	at 
org.eclipse.xtext.generator.JavaIoFileSystemAccess.generateFile(JavaIoFileSystemAccess.java:81)
	at 
org.eclipse.xtext.generator.AbstractFileSystemAccess.generateFile(AbstractFileSystemAccess.java:75)
....

Basically the problem occurs in XMLEncodingProvider#getEncoding() which
creates an input stream without checking properly if the file exists before.

Did I forget to setup something or is it a bug?

Hi,

the encoding provider is for reading model (xmi) files. so it may not been optimized for the use in the generator.
sounds like a bug to me.

Hi,

i can confirm this for 1.3.0.v201302260541 in Juno. Strange enough, when I run it from an eclipse via "run as -> eclipse application", it works all fine without that exception. Installing the plugin and running this eclipse, I get the error above. Even with the exception being thrown, all files are generated.
