Issue details

Was reviewing pulumi/examples#1260

The error message could be better.

Work items

• Consider more brief error display when there is an exception #763
• deduplicate error output(likely stderr/stdout)
• trim stacktrace
• improve missing config value error message(indicate the missing config value and how to set it)

Affected area/feature

#817 might be a related related to this one

regarding:

improve missing config value error message(indicate the missing config value and how to set it)

ctx.config.get("bleh") returns an Optional so there is no error, and ctx.config.require("bleh") works as expected:

Diagnostics:
  pulumi:pulumi:Stack (random-java-random):
    error: Missing required configuration variable 'random:bleh'
    	please set a value using the command `pulumi config set random:bleh <value>`
    error: an unhandled error occurred: '/usr/local/bin/mvn /usr/local/bin/mvn -Dorg.slf4j.simpleLogger.defaultLogLevel=warn --no-transfer-progress compile exec:java' exited with non-zero exit code: 32

please let me know what improvements you've had in mind :)

[pawelprazak]

I've made a small change that should address the most visible problem of perceived duplication.
