要么配置resources:resources插件的outputDirectory参数，要么将文件放在src/main/webapp/WEB-INF/目录下. 资源插件

either configure the outputDirectory parameter of resources:resources plugin, or put your files under src/main/webapp/WEB-INF/ directory. resource plugin

此配置对我有用:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.2</version>
    <executions>
      <execution>
        <id>default-copy-resources</id>
        <phase>process-resources</phase>
        <goals>
          <goal>copy-resources</goal>
        </goals>
        <configuration>
          <overwrite>true</overwrite>
          <outputDirectory>${project.build.directory}/${project.artifactId}-${project.version}/WEB-INF/</outputDirectory>
          <resources>
            <resource>
              <directory>${project.basedir}/src/main/resources</directory>
            </resource>
          </resources>
        </configuration>
      </execution>
    </executions>
  </plugin>

您可以运行somePhase形式或目标somePlugin:someGoal形式的阶段.阶段调用将按间隔[validate，phase]的顺序调用挂在阶段上的所有插件目标，因此无需显式调用它们.

you can run a phase in the form somePhase or a goal somePlugin:someGoal. The phase invocations will invoke all plugins goals hooked on phases in interval [validate,phase] in order, so there's no need to explicitly call them.
