备忘：maven 错误信息： Plugin execution not covered by lifecycle configuration

在一个pom文件中，由于需要设置了一下几个默认goal的版本号，如下：

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.19.1</version>
                <configuration>
                    <forkMode>once</forkMode>
                    <argLine>-Dfile.encoding=UTF-8</argLine>
                </configuration>
            </plugin>
        </plugins>
    </build>

结果执行maven test之类没问题，但是eclipse一直报  "Plugin execution not covered by lifecycle configuration...."，网上找了一下解决方案，原来这些默认的goal应该放到<pluginManagement>里，如下：

    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.5.1</version>
                    <configuration>
                        <source>1.7</source>
                        <target>1.7</target>
                    </configuration>
                </plugin>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.19.1</version>
                    <configuration>
                        <forkMode>once</forkMode>
                        <argLine>-Dfile.encoding=UTF-8</argLine>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

个人理解，放到pluginManagement只是替换指定的goal，而直接放到build下的话，则被认为是替换所有的goal。
