                <artifactId>build-helper-maven-plugin</artifactId>
                <version>1.8</version>
                <executions>
                    <execution>
                        <id>add-resource</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>add-resource</goal>
                        </goals>
                        <configuration>
                            <resources>
                                <resource>
                                    <directory>src/main/java</directory>
                                    <includes>
                                        <include>**/*.xml</include>
                                    </includes>
                                </resource>
                            </resources> 
                        </configuration>
                      </execution>
                 </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.19.1</version>
                <configuration>
                    <useSystemClassLoader>false</useSystemClassLoader>
                </configuration>
            </plugin>

2：报错信息如下

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:build-helper-maven-plugin:1.8:
　　add-resource (execution: add-resource, phase: generate-resources) pom.xml

3：错误原因

eclipse的m2e插件还没支持到execution
