Plugin org.apache.maven.plugins:maven-compiler-plugin or one of its dependencies could not be resolved

I’m having some issues to configure properly my eclipse to work with maven.

I create a new project, this one is correctly build with maven in command line (mvn install), but in Eclipse I got this error:

CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 (): ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.maven:maven-settings:jar:2.2.1: ArtifactResolutionException: Failure to transfer org.apache.maven:maven-settings:pom:2.2.1 from was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven:maven-settings:pom:2.2.1 from/to central : NullPointerException pom.xml /test line 9 Maven Project Build Lifecycle Mapping Problem

Here is my settings.xml conf :


     <name>central repo m2</name>

I choose the correct maven installation (in Preference -> Maven -> Install)

I also direct my user settings on the correct settings.xml (Preferences -> Maven -> User Settings)

But I still got this error in Eclipse and everything goes well with maven command line. Do you have and idea?


Have you tried to remove the proxy username and password? A similar poster encountered that issue:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Failing that I found the following worked:

  1. Delete project in Eclipse (but do not delete the contents on disk)
  2. Delete all files in your Maven repository
  3. Re-download all Maven dependencies:

mvn dependency:resolve

  1. Start up Eclipse
  2. Ensure that Eclipse is configured to use your external Maven installation (Window->Preferences->Maven->Installations)
  3. Re-import the existing project(s) into Eclipse
  4. Ensure that there are no Maven Eclipse plugin errors on the final screen of the project import
