Unknown lifecycle phase maven

you have likely a space between -Dtest= and SpringTransformMethodTest. That's then interpreted as 2 items instead of one.

I got the error also

[ERROR] Unknown lifecycle phase "pacakge". You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. 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, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

you may type wrong command change 'pacakge' to 'package'

If the parameter name is not a single 'word' you might also need to enclose it in quotation marks like this:

mvn gatling:test -D"gatling.simulationClass"="my.package.PostmanSimulation"

This error has happened to me as well. I was running this command which hasn't spaces between the parameters of mvn install its values.

With this command:

> mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file 
-Dfile=C:\Users\arcones\Desktop\ojdbc7.jar 
-DgroupId=com.oracle 
-DartifactId=ojdbc7 
-Dversion=12.1.0.1 
-Dpackaging=jar 
-DlocalRepositoryPath=lib

I got this error:

[ERROR] Unknown lifecycle phase ".oracle". 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, genera te-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-class es, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, depl oy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

The problem got resolved by adding double quotes to each value:

> mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file 
-Dfile="C:\Users\arcones\Desktop\ojdbc7.jar" 
-DgroupId="com.oracle"
-DartifactId="ojdbc7"
-Dversion="12.1.0.1"
-Dpackaging="jar" 
-DlocalRepositoryPath="lib"
