You have to specify any one of the above phase to resolve the above error. In most of the situations, this would have occurred due to running the build from the eclipse environment.

instead of mvn clean package or mvn package you can try only package its work fine for me

I too got the similar problem and I did like below   Rt click the project  navigate to Run As --  click 6 Maven Clean and your build will be success

Try without command mvn in the command line  Example   From   mvn clean install jetty run   To   clean install jetty run

Sometimes this error comes because it s simply the wrong folder   -   It shall be the folder which contains the pom xml

I was getting the same error  I was using Intellij IDEA and I wanted to run Spring boot application  So  solution from my side is as follow   Go to Run menu -  Run configuration -  Click on Add button from the left panel and select maven -  In parameters add this text -  spring-boot run  Now press Ok and Run

Thanks for the reply   I was using  mvn clean install  in the maven build configuration  we no need to use  mvn  command if running through eclipse   After buiding the application using the command  clean install    I got one more error -  No compiler is provided in this environment  Perhaps you are running on a JRE rather than a JDK    I followed this link - No compiler is provided in this environment  Perhaps you are running on a JRE rather than a JDK   now application building is fine in eclipse

Create new Maven file with path as classpath and goal as class name

User · Answer

If you are using debug configuration for maven  use the  command  clean install   And skip all the tests

[maven] Unknown lifecycle phase "mvn". You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>
