I am trying to build our web project from the commandline but skipping the testing. I am using the command mvn clean install -Dmaven.test.skip=true.
When I run the command from the traditional black & white Command Prompt (aka DOS shell) the command works, but when I run it from the command from "Windows PowerShell" I get the following error:
[ERROR] Unknown lifecycle phase ".test.skip=true". You must specify a valid lifecycle phase or a goal in the format : or :[:]:. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepar e-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-site, site, post-site, site-deploy, pre-clean, clean, post-clean. -> [Help 1]`
What is causing this discrepancy and how do I get PowerShell to behave like the traditional Command Prompt?
This is running on Windows 7.
When you run into problems with PowerShell's interpretation of arguments to be passed to a console EXE, try using the echoargs.exe utility that comes with the PowerShell Community Extensions. With this tool you can see how PowerShell supplies the arguments to the EXE e.g.:
PS> echoargs mvn clean install -Dmaven.test.skip=true
Arg 0 is <mvn>
Arg 1 is <clean>
Arg 2 is <install>
Arg 3 is <-Dmaven>
Arg 4 is <.test.skip=true>
PS> echoargs mvn clean install '-Dmaven.test.skip=true'
Arg 0 is <mvn>
Arg 1 is <clean>
Arg 2 is <install>
Arg 3 is <-Dmaven.test.skip=true>
Short answer - use quoting '-Dmaven.test.skip=true'
