在eclipse中使用maven-dependency-plugin报错maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.，,错误信息：maven-d

错误信息：maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.从字面意思上看就是m2e插件不支持"copy-dependencies", "unpack"。

此问题可以通过在pom.xml的build节点中添加pluginManagement节点来解决，如下是添加到build节点中的pluginManagment节点：

<pluginManagement>              <plugins>                  <plugin>                      <groupId>org.eclipse.m2e</groupId>                      <artifactId>lifecycle-mapping</artifactId>                      <version>1.0.0</version>                      <configuration>                          <lifecycleMappingMetadata>                              <pluginExecutions>                                  <pluginExecution>                                      <pluginExecutionFilter>                                          <groupId>org.apache.maven.plugins</groupId>                                          <artifactId>maven-dependency-plugin</artifactId>                                          <versionRange>[2.0,)</versionRange>                                          <goals>                                              <goal>copy-dependencies</goal>                                          </goals>                                      </pluginExecutionFilter>                                      <action>                                          <ignore />                                      </action>                                  </pluginExecution>                              </pluginExecutions>                          </lifecycleMappingMetadata>                      </configuration>                  </plugin>              </plugins>          </pluginManagement> 

添加上述信息之后，就不会再有maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.的错误了。
