jonpspri opened a new pull request #4: Add more descriptive error message for unset OPENWHISK_HOME
URL: https://github.com/apache/incubator-openwhisk-runtime-nodejs/pull/4
 
 
   Attempting build with OPENWHISK_HOME unset (and openwhisk not in a specific default) caused an unhelpful error message:
   
   ```
   FAILURE: Build failed with an exception.
   
   * Where:
   Build file '/home/jonpspri/Projects/openwhisk-runtime-nodejs/tests/build.gradle' line: 23
   
   * What went wrong:
   A problem occurred evaluating project ':tests'.
   > Could not get unknown property 'sourceSets' for project ':whisktests' of type org.gradle.api.Project.
   ```
   
   Changes instead produce an error message that identifies the problem and correct it:
   
   ```
   FAILURE: Build failed with an exception.
   
   * Where:
   Settings file '/Users/jpspring/Projects/incubator-openwhisk-runtime-nodejs/settings.gradle' line: 5
   
   * What went wrong:
   Environment variable OPENWHISK_HOME must point to a valid OpenWhisk build
   ```
