maven lifecycle configuration for eclipse

在Eclipse当中使用wro4j-maven-plugin做代码压缩时候出现问题

问题现象:

Plugin execution not covered by lifecycle configuration: ro.isdc.wro4j:wro4j-maven-plugin:1.7.6:run (execution: default, phase: generate-resources)	pom.xml	/angularjs-security	line 85	Maven Project Build Lifecycle Mapping Problem

解决方式:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!--巴拉巴拉 省略 -->
        </plugins>

        <!--配置下面代码告诉Eclipse如何编译-->
        <!-- configure #!@ m2eclipse -->
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.eclipse.m2e</groupId>
                    <artifactId>lifecycle-mapping</artifactId>
                    <version>1.0.0</version>
                    <configuration>
                        <lifecycleMappingMetadata>
                            <pluginExecutions>
                                <pluginExecution>
                                    <pluginExecutionFilter>

                                        <versionRange>[1.0,]</versionRange>
                                        <goals>
                                            <goal>run</goal>
                                        </goals>
                                    </pluginExecutionFilter>
                                    <action>
                                        <execute>
                                            <runOnIncremental>true</runOnIncremental>
                                        </execute>
                                    </action>
                                </pluginExecution>
                            </pluginExecutions>
                        </lifecycleMappingMetadata>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>

</build>

问题研究(这算是一类问题)
since Eclipse is all about incremental building (i.e. builds modified resources as soon as they're saved),

triggering long-running maven plugin every time a file is changed in the workspace would be a disaster. So m2e requires users to be explicit about what maven plugins should be run and when.

As a consequence, in order for these unknown plugins to be run on incremental builds, users need to modify their project pom.xml (or their parent pom.xml) and add a lifecycle-mapping configuration like (in the case of wro4j) :
