[java] 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 http://repo.maven.apache.org/maven2 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 :

<proxy>
  <active>true</active>
  <protocol>http</protocol>
  <username>myuser</username>
  <password>$mymdp</password>
  <host>myhost</host>
  <port>8080</port>
  <nonProxyHosts>some.host.com</nonProxyHosts>
</proxy>
....

<repository>
     <id>central</id>
     <name>central repo m2</name>
     <url>http://central.maven.org/maven2</url>
</repository>

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?

You only need to delete one folder it is throwing error for. Just go to your M2 repo and org/apache/maven/plugins/maven-compiler-plugins and delete the folder 2.3.2

I also got the same issue and not able to create a jar, and I found that in Windows-->Prefernces-->Java-->installed JREs By default JRE was added to the build path of newly created java project so just changed it to your prefered JDK.

I was getting this problem when using IBM RSA 9.6.1 when building a brand new development machine. The problem for me ended up being because of HTTPS on the Global Maven repository. My solution was to create a Maven settings.xml that forced it to use HTTP.

The key to me was that the central repository was empty when I exploded it under Maven Repositories -- > Global Repositories

Using the following settings file worked for me:

<settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>insecurecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>insecurecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>

I got the idea from this stackoverflow question.

I accidentally turned on offline mode.

To disable it: in the Maven tool window, click The Toggle Offline Mode button.

The issue has been resolved while installation of the maven settings is provided as External in Eclipse. The navigation settings are Window --> Preferences --> Installations. Select the External as installation Type, provide the Installation home and name and click on Finish. Finally select this as default installations.
