How do I set test.testLogging.showStandardStreams to true from the command line?
gradle
Solution
There is no built-in way to set build model properties from the command line. You'll have to make the build script query a system or project property that gets passed in via `-D` or `-P`, respectively.
Problem
It is convenient to debug some of external libraries and even internal code while writing unit tests by reviewing the logging on stdout. While I can add `test.testLogging.showStandardStreams = true` to the build.graddle file, I'd rather do something less permanent, such as setting this flag from the command line execution of gradle. I've tried several approaches, none seem to work: ``` gradle test -Dtest.testLogging.showStandardStreams=true gradle test -Ptest.testLogging.showStandardStreams=true ``` And other variations of those options by changing the property string. Nothing seems to do the trick. How do I set `test.testLogging.showStandardStreams=true` from the command line?
