Maven错误：生命周期配置未涵盖插件执行：

Question

您好，我是Maven的新手，我首先尝试按照链接的本指南查找[解决方案] 这是导致问题的插件的pom.xml中的一个片段...

下面是一个片段

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${maven-compiler-plugin.version}</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
          <compilerArgument>-Xlint:unchecked</compilerArgument>
          <!-- Checks to see if there are deprecated Methods -->

          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </pluginManagement>
</build>

这是我的错误： -生命周期配置未涵盖的插件执行：org.apache.maven.plugins：maven-compiler-plugin：3.6.2：compile（执行：默认编译，阶段：编译） -生命周期配置未涵盖的插件执行：org.apache.maven.plugins：maven-compiler-plugin：3.6.2：testCompile（执行：default-testCompile，阶段：test-compile）
