xcodebuild: error: Unknown build action

Question

When I'm try to build from the command line:

xcodebuild -target -project myApp.xcodeproj -scheme myApp -sdk iphoneos -configuration Release archive -archivePath $PWD/build/DDCiOSClient.xcarchive

I'm getting this error:

User defaults from command line:
    IDEArchivePathOverride = /depot/myApp/myApp.xcarchive

Build settings from command line:
    SDKROOT = iphoneos9.3

xcodebuild: error: Unknown build action 'myApp.xcodeproj'.

Any of you knows why of this error?

Solution

The phrase -target -project is meaningless. You need to supply a target after the -target argument name.

Also, the action archive needs to come last.
