Generator: "Sculptor code generator failed" without details

[rcodesmith]

Running off the latest code, I'm getting the following failure in a Maven build:

I don't see any error messages indicating the reason for the failure.

Ok, the first line "[ERROR] Executing generator workflow failed" is logged if SculptorGeneratorRunner.run() returns null. This is the case if the new Xtend-based Sculptor workflow in SculptorGeneratorWorkflow.run() "falls through" and returns false:

    def final boolean run(String modelURI, Properties properties) {
        updateConfiguration(properties)
        if (readModel(modelURI)) {
            if (validateResources()) {
                val dslApp = getApplication()
                if (validateApplication(dslApp)) {
                    val app = transformAndModifyApplication(dslApp)
                    if (app != null) {
                        if (generateCode(app) != null) {
                            return true
                        }
                    }
                }
            }
        }
        false
    }

It seems that these workflow steps aren't logging enough to get an idea on what's going wrong.

Please run mvn clean generate-resourceson this project with the verbose attribute set in the configuration of Sculptors Maven plugin (or use the Maven option -X) and attach the debug output of the plugin.

[tjuerge]

Please re-run your build using the Sculptor plugin with the improved logging in the workflow introduced in 6df8d09.

The documentation of Sculptors Maven plugin provides now a chapter on activating debug logging of Sculptors generator library. Please check if this information is helpful here.

Please check if #145 solves this issue.
