maven，pom.xml里配置了插件，是怎么使用的？

Question

初学maven，问个基础问题

pom.xml部分信息

  <build>
    <finalName>TestSpringBoot</finalName>
    <pluginManagement>
 <plugins>
  <plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
  </plugin>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>3.1</version>
          <configuration>
            <tasks>
            <echo>Test.....................</echo>
            </tasks>
          </configuration>
        </plugin>
 </plugins>
 </pluginManagement>
  </build>

maven-compiler-plugin插件，应该输出一行信息Test......

应该怎么执行这个插件啊？

我运行了mvn compile，输出

没有test.......，怎么回事

另外，前三行的警告是啥意思

Answer 1

这个插件的 configuration 里并没有 <tasks> 这个配置呀，当然没有 Test 输出啦~你是不是把这插件和 antrun 插件搞混了？
