This worked for me too  Later  I ended-up switching to the maven-antrun-plugin to avoid warnings in Eclipse  And I prefer using default plugins when possible  Example   lt plugin gt       lt artifactId gt maven-antrun-plugin lt  artifactId gt       lt version gt 3 0 0 lt  version gt       lt executions gt           lt execution gt               lt id gt get-the-hostname lt  id gt               lt phase gt package lt  phase gt               lt configuration gt                   lt target gt                       lt exec executable  quot bash quot  gt                           lt arg value  quot -c quot   gt                           lt arg value  quot hostname quot   gt                       lt  exec gt                   lt  target gt               lt  configuration gt               lt goals gt                   lt goal gt run lt  goal gt               lt  goals gt           lt  execution gt       lt  executions gt   lt  plugin gt

2 Options    You want to exec a command from maven without binding to any phase  you just type the command and maven runs it  you just want to maven to run something  you don t care if we are in compile package      Let s say I want to run npm start with maven  you can achieve it with the below    mvn exec exec -Pstart-node  For that you need the below maven section     lt profiles gt       lt profile gt         lt id gt start-node lt  id gt         lt build gt           lt plugins gt             lt plugin gt               lt groupId gt org codehaus mojo lt  groupId gt               lt artifactId gt exec-maven-plugin lt  artifactId gt               lt version gt 1 3 2 lt  version gt               lt executions gt                 lt execution gt                   lt goals gt                     lt goal gt exec lt  goal gt                   lt  goals gt                 lt  execution gt               lt  executions gt               lt configuration gt                 lt executable gt npm lt  executable gt                 lt arguments gt  lt argument gt start lt  argument gt  lt  arguments gt               lt  configuration gt             lt  plugin gt           lt  plugins gt         lt  build gt       lt  profile gt      lt  profiles gt     You want to run an arbitrary command from maven while you are at a specific phase  for example when I m at install phase I want to run npm install you can do that with    mvn install   And for that to work you would need the below section      lt plugin gt       lt groupId gt org codehaus mojo lt  groupId gt       lt artifactId gt exec-maven-plugin lt  artifactId gt       lt version gt 1 3 2 lt  version gt       lt executions gt          lt execution gt           lt id gt npm install  initialize  lt  id gt           lt goals gt             lt goal gt exec lt  goal gt           lt  goals gt           lt phase gt initialize lt  phase gt           lt configuration gt             lt executable gt npm lt  executable gt             lt arguments gt               lt argument gt install lt  argument gt             lt  arguments gt           lt  configuration gt         lt  execution gt

Solved  The problem is  executable is working in a different way in Linux  If you want to run an  sh file  you should add the exec-maven-plugin to the  lt plugins gt  section of your pom xml file   lt plugin gt     lt artifactId gt exec-maven-plugin lt  artifactId gt     lt version gt 3 0 0 lt  version gt     lt groupId gt org codehaus mojo lt  groupId gt     lt executions gt       lt execution gt         lt  -- Run our version calculation script -- gt         lt id gt Renaming build artifacts lt  id gt         lt phase gt package lt  phase gt         lt goals gt           lt goal gt exec lt  goal gt         lt  goals gt         lt configuration gt           lt executable gt bash lt  executable gt           lt commandlineArgs gt handleResultJars sh lt  commandlineArgs gt         lt  configuration gt       lt  execution gt     lt  executions gt   lt  plugin gt

The problem here is that I don t know what is expected  With your current setup  invoking the plugin on the command line would just work      mvn exec exec  INFO  Scanning for projects     INFO  ------------------------------------------------------------------------  INFO  Building Q3491937  INFO     task-segment   exec exec   INFO  ------------------------------------------------------------------------  INFO   exec exec  execution  default-cli    INFO  laptop  INFO  ------------------------------------------------------------------------  INFO  BUILD SUCCESSFUL  INFO  ------------------------------------------------------------------------       The global configuration is used  the hostname command is executed  laptop is my hostname   In other words  the plugin works as expected   Now  if you want a plugin to get executed as part of the build  you have to bind a goal on a specific phase  For example  to bind it on compile      lt plugin gt       lt groupId gt org codehaus mojo lt  groupId gt       lt artifactId gt exec-maven-plugin lt  artifactId gt       lt version gt 1 1 1 lt  version gt       lt executions gt         lt execution gt           lt id gt some-execution lt  id gt           lt phase gt compile lt  phase gt           lt goals gt             lt goal gt exec lt  goal gt           lt  goals gt         lt  execution gt       lt  executions gt       lt configuration gt         lt executable gt hostname lt  executable gt       lt  configuration gt     lt  plugin gt    And then      mvn compile  INFO  Scanning for projects     INFO  ------------------------------------------------------------------------  INFO  Building Q3491937  INFO     task-segment   compile   INFO  ------------------------------------------------------------------------  INFO   resources resources  execution  default-resources    INFO  Using  UTF-8  encoding to copy filtered resources   INFO  skip non existing resourceDirectory  home pascal Projects Q3491937 src main resources  INFO   compiler compile  execution  default-compile    INFO  Nothing to compile - all classes are up to date  INFO   exec exec  execution  some-execution    INFO  laptop  INFO  ------------------------------------------------------------------------  INFO  BUILD SUCCESSFUL  INFO  ------------------------------------------------------------------------       Note that you can specify a configuration inside an execution
