I have a fairly simple Maven project    lt project gt       lt dependencies gt                   lt  dependencies gt        lt build gt           lt plugins gt               lt plugin gt                   lt groupId gt org apache maven plugins lt  groupId gt                   lt artifactId gt maven-dependency-plugin lt  artifactId gt                   lt version gt 2 4 lt  version gt                   lt executions gt                       lt execution gt                           lt id gt copy-dependencies lt  id gt                           lt phase gt package lt  phase gt                           lt goals gt                               lt goal gt copy-dependencies lt  goal gt                           lt  goals gt                           lt configuration gt                               lt outputDirectory gt   project build directory  dependencies lt  outputDirectory gt                           lt  configuration gt                           lt  execution gt                   lt  executions gt               lt  plugin gt           lt  plugins gt       lt  build gt   lt  project gt    However  I get the following error in m2eclipse   Description Resource    Path    Location    Type maven-dependency-plugin  goals  copy-dependencies    unpack   is not supported by m2e  pom xml   jasperreports-test line 60 Maven Project Build Lifecycle Mapping Problem   Why do I care if m2eclipse doesn t  support  this task  Maven does  and that s all I really care about  How can I get this error in my project to go away

Another option is to navigate to problems tab  right click on error  click apply quick fix  The should generate the ignore xml code and apply it  pom file for you

It seems to be a known issue  You can instruct m2e to ignore this    Option 1  pom xml  Add the following inside your  lt build  gt  tag    lt pluginManagement gt   lt plugins gt       lt  -- Ignore Execute plugin execution -- gt       lt plugin gt           lt groupId gt org eclipse m2e lt  groupId gt           lt artifactId gt lifecycle-mapping lt  artifactId gt           lt version gt 1 0 0 lt  version gt           lt configuration gt               lt lifecycleMappingMetadata gt                   lt pluginExecutions gt                       lt  -- copy-dependency plugin -- gt                       lt pluginExecution gt                           lt pluginExecutionFilter gt                               lt groupId gt org apache maven plugins lt  groupId gt                               lt artifactId gt maven-dependency-plugin lt  artifactId gt                               lt versionRange gt  1 0 0   lt  versionRange gt                               lt goals gt                                   lt goal gt copy-dependencies lt  goal gt                               lt  goals gt                           lt  pluginExecutionFilter gt                           lt action gt                               lt ignore   gt                           lt  action gt                       lt  pluginExecution gt                   lt  pluginExecutions gt               lt  lifecycleMappingMetadata gt           lt  configuration gt       lt  plugin gt      lt  plugins gt  lt  pluginManagement gt    You will need to do Maven    -  Update Project Configuration on your project after this   Read more  http   wiki eclipse org M2E plugin execution not covered m2e maven plugin coverage status  Option 2  Global Eclipse Override  To avoid changing your POM files  the ignore override can be applied to the whole workspace via Eclipse settings   Save this file somewhere on the disk  https   gist github com maksimov 8906462  In Eclipse Preferences Maven Lifecycle Mappings browse to this file and click OK

If copy-dependencies  unpack  pack  etc   are important for your project you shouldn t ignore it  You have to enclose your  lt plugins gt  in  lt pluginManagement gt  tested with Eclipse Indigo SR1  maven 2 2 1

This is a problem of M2E for Eclipse M2E plugin execution not covered   To solve this problem  all you got to do is to map the lifecycle it doesn t recognize and instruct M2E to execute it   You should add this after your plugins  inside the build  This will remove the error and  make M2E recognize the goal copy-depencies of maven-dependency-plugin and make the POM work as expected  copying dependencies to folder every time Eclipse build it  If you just want to ignore the error  then you change  lt execute   gt  for  lt ignore   gt   No need for enclosing your maven-dependency-plugin into pluginManagement  as suggested before    lt pluginManagement gt     lt plugins gt       lt plugin gt         lt groupId gt org eclipse m2e lt  groupId gt         lt artifactId gt lifecycle-mapping lt  artifactId gt         lt version gt 1 0 0 lt  version gt         lt configuration gt           lt lifecycleMappingMetadata gt             lt pluginExecutions gt               lt pluginExecution gt                 lt pluginExecutionFilter gt                   lt groupId gt org apache maven plugins lt  groupId gt                   lt artifactId gt maven-dependency-plugin lt  artifactId gt                   lt versionRange gt  2 0   lt  versionRange gt                   lt goals gt                     lt goal gt copy-dependencies lt  goal gt                   lt  goals gt                 lt  pluginExecutionFilter gt                 lt action gt                   lt execute   gt                 lt  action gt               lt  pluginExecution gt             lt  pluginExecutions gt           lt  lifecycleMappingMetadata gt         lt  configuration gt       lt  plugin gt     lt  plugins gt   lt  pluginManagement gt

I had the same problem when trying to load Hadoop project in eclipse  I tried the solutions above  and I believe it might have worked in Eclipse Kepler    not even sure anymore  tried too many things     With all the problems I was having  I decided to move on to Eclipse Luna  and the solutions above did not work for me    There was another post that recommended changing the     tag to package  I started doing that  and it would  clear  the errors    However  I start to think that the changes would bite me later - I am not an expert on Maven    Fortunately  I found out how to remove all the errors  Go to Window- Preferences- Maven-  Error Warnings and change  Plugin execution not covered by lifecycle     option to  Ignore   Hope it helps

To make it work  instead of ignoring it  you can install the m2e connector for the maven-dependency-plugin  https   github com ianbrandt m2e-maven-dependency-plugin  Here is how you would do it in Eclipse    go to Window Preferences Maven Discovery  enter Catalog URL  http   download eclipse org technology m2e discovery directory-1 4 xml click Open Catalog choose the m2e-maven-dependency-plugin enjoy
