Error

[ERROR] Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:3.1 from/to central (https://repo.maven.apache.org/maven2): java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

Error says its not able to download artifact from http://repo.maven.apache.org/maven2 url, but am not downloading this url. I've mentioned different in setting.xml.

Is there any way to solve this problem or I could change any setting so that it dont go to this url http://repo.maven.apache.org/maven2 to download but the one mentioned in setting.xml ?

Tried almost all options, like deleting maven repository, mvn install, force updates, deleting project, re-starting eclipse etc etc.

Any help would be appreciated . Really Stuck

Thanks

In maven's semantic versioning, 3.1 and 3.1.0 are not the same thing. Maven't can't locate version 3.1 for this plugin simply because it does not exist. You need to refer to the 3.1.0 version you correctly referred to in the dependencies:

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <artifactId>maven-resources-plugin</artifactId>
        <version>3.1.0</version> <!-- Here, instead of 3.1 you had in the question -->
      </plugin>           
    </plugins>
  </pluginManagement>   
</build>
