"The PluginDescriptor not found" error when executing copy-resources maven-resources-plugin's goal

As part of my pom.xml I copy some extra resources to the target directory as follows.

 <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <version>2.开发者_开发问答4.1</version>
  <executions>
   <execution>
    <id>copy-package-doc</id>
    <phase>package</phase>
    <goals>
     <goal>copy-resources</goal>
    </goals>
    <configuration>
     <outputDirectory>${project.build.directory}/package/${project.artifactId}-${project.version}/doc</outputDirectory>
     <nonFilteredFileExtensions>
      <nonFilteredFileExtension>doc</nonFilteredFileExtension>
     </nonFilteredFileExtensions>
     <resources>
      <resource>
       <directory>doc</directory>
       <filtering>true</filtering>
       <includes>
        <include>**/*.doc</include>
       </includes>
       <excludes>
        <exclude>**/~*.doc</exclude>
       </excludes>
      </resource>
     </resources>
    </configuration>
   </execution>
   <execution>
    <id>copy-package-config</id>
    <phase>package</phase>
    <goals>
     <goal>copy-resources</goal>
    </goals>
    <configuration>
     <outputDirectory>${project.build.directory}/package/${project.artifactId}-${project.version}</outputDirectory>
     <resources>
      <resource>
       <directory>config</directory>
       <filtering>true</filtering>
      </resource>
     </resources>
    </configuration>
   </execution>
  </executions>
 </plugin>

When I package artifact I get error:

The PluginDescriptor for the plugin org.apache.maven.plugins:maven-resources-plugin was not found. Should have been in realm: ClassRealm[/plugins/org.apache.maven.plugins:maven-resources-plugin:2.4.1@48/thread:Worker-17, parent: null]

How to fix that? Why I get this error?

Thanks, Rafal

Include info on version used for: eclipse, java, maven

Try running mvn package -U -e and include output on pastebin.

Also try using another version of resources-plugin <version>2.3</version> or why do you need 2.4.1

Sounds like you got a corrupted maven plugin

Try deleting the folder maven-resources-plugin contained in .m2/repository/org/apache/maven

Or post (or include link to) whole error message

I've seen lots of similar issues on the web (e.g. in IDEA-16866, IDEADEV-24376, MIDEA-109 or this one about Eclipse/IAM which seems to be the closest). In all cases, this seems related to Maven Embedder.

I have actually no idea of the cause of the problem and have no better suggestion than to use the latest version of maven (2.2.1) if it's not the case and/or to try with previous versions of the maven-resources-plugin (2.3) to verify that this is not a regression.

If this doesn't work, go the Maven 2.x Resources Plugin Jira and open an issue.

I have switched from Q for Eclipse to M2Eclipse and this solved my problem.
