Unknown Lifecycle Phase Error in Maven Build

Problem

[ERROR] Unknown lifecycle phase "test1". 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]

If you look at the above error “Unknown lifecycle phase”, your build could not detect the pre-defined lifecycle phase used by Maven. Maven has the following phases:

• validate – validate the project is correct and all necessary information is available
• compile – compile the source code of the project
• test – test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
• package – take the compiled code and package it in its distributable format, such as a JAR.
• integration-test – process and deploy the package if necessary into an environment where integration tests can be run
• verify – run any checks to verify the package is valid and meets quality criteria
  
• install – install the package into the local repository, for use as a dependency in other projects locally
• deploy – done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects
  Solution is: package
