Maven 阴影插件未执行

Question

在我当前的项目设置中，maven shade插件的执行非常不一致。该插件看起来像是在我构建父模块后执行的，但是在该实例中执行后，它在独立构建子模块时无法执行。

如您所见，尽管在父 pom 的<plugins>部分中定义了执行，但 maven shade 插件并未执行。

您需要将插件附加到 maven 执行阶段。请参阅Shade插件文档中的此示例(请参阅它如何附加到package阶段(：

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
          <!-- put your configurations here -->
        </configuration>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
