Hi,

in my latest project I have a problem with the .genmodel file. It always tells me that it encountered a problem. The error message is:

org.eclipse.emf.ecore.xmi.XMIException: org.xml.sax.SAXParseExceptionpublicId: platform:/resource/myProject /plugin.properties; systemId: platform:/resource/myProject/plugin.properties; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog. (platform:/resource/myproject/plugin.properties, 1, 1)

From that error message I assumed, that the problem originates form the plugin.properties file. Thus I checked the file and it says:

#

pluginName = myProject Model
providerName = www.example.org

When I compare that file to any other freshly generated plugin.properties file in another project, there is no difference, but the new file does not show any problems. I have the exact same problem with the build.properties.

Has anyone any idea, how I can fix this?

Hi

Probably by not using a *.properties file where an XML file is expected. Seems like a typo, but without sharing your build script/commands with us it is hard to be sure. I have seen the bad publicId/systemId message many times from improperly configured models, but never from a *.properties file since *.properties files are not part of the primary genmodel process; they are just updated once genmodel is underway.

If you include the full stack trace then we can see from where this resource is being loaded. It's certainly not normal that there should be an attempt to load a *.properties file as if it were an XML file and it's hard to imagine what could possibility cause such a thing. A full stack trace would help clarify that point.

Hi

Looks like a Sirius-assisted bug. Whatever you do in Sirius should not make a *.properties a source file. As always, without a repro, you make it very hard for responses to be more than guesses.

This is happening in a background job, and the GenModel editor does do "live validation" via a job like this. But in that case, the problem could only happen if your *.genmodel or *.ecore model (or some model on which either of them depend) has a reference to this Sirius view point model. It might also be happening directly via a job launched by Sirius. In either case, it is not a problem that I can fix. And as Ed suggests, if the Sirius folks are to fix it, they'll likely need a way to reproduce the problem. This is their forum:

Hi

One possibility....

Sirius has a fairly aggressive search for possible models that then get stuck in the *.aird file. It might be that you had some accident with the *.properties that fooled Sirius into treating it as a model file and now you are stuck with it. Search your *.aird files for any references to properties files and delete them manually. Put everything in GIT before you start manual deletions in case you make things worse.
