NullPointerException when using DX to push to scratch org

[Chuck Liddell]

Filing this as "blocker" but hoping I've just done something stupid on my end to gum up the works.

I updated to 1.8.0.8 and now I am seeing a NullPointerException in IDEA when I try to push metadata to a scratch org using sfdx.

As the NullPointerException pops I get the following message in my Event Log:

9:57 PM Error running Salesforce DX
                ▸    Flag --targetusername expects a value

When I use SFDX from the command line myself, the push is fine.

Here's some more context with what happens when I try various operations:

1. Push Metadata: NullPointerException and error message about targetusername

2. Pull Metadata: Error message about targetusername (no exception though)

3. Clicking connection dropdown in menubar and clicking my scratch org: opens scratch org in web browser successfully

4. Generate Offline Symbol Table: Error popup "The connection is invalid. Please select or create a valid connection and try the operation again."

Attached a log file. Actions taken to generate the log:

1. start the IDE

2. try to do a pull metadata

3. try to do a push metadata

Two exceptions thrown in the log, one at application start and one when attempting to push.

Chuck, do you mind adding the following to Help>Debug Log Settings and reproducing the issue?

#com.illuminatedcloud.intellij.sfdx.SfdxUtil
#com.illuminatedcloud.util.CommandLineUtil

Then please send me the log. Note that this log will have detailed information so feel free to email it to me if you'd prefer. Once I see what's going on I should be able to turn around a fix very quickly.
