【问题描述】：

我尝试从 eclipse 的旧项目中执行 maven 构建文件使用日食：

Version: Kepler Service Release 1
Build id: 20130919-0819

我有这个不断出错的 maven 代码：

<build>
  <pluginManagement>
    <plugins>
      <!-- Use version 2.3 of the resources plugin 
       to pickup a needed filtering bugfix -->
      <plugin>                
        <artifactId>maven-resources-plugin</artifactId>
        <version>2.4.3</version>
      </plugin>
    </plugins>

    <!-- Enable filtering of the properties files -->
    <testResources>
      <testResource>
            <directory>src/test/properties</directory>
            <filtering>true</filtering>
      </testResource>
    </testResources>
    </pluginManagement>
  </build>

标签：标记为红色，错误提示：

cvc-complex-type.2.4.d: Invalid content was found starting   with element 'testResources'. No child element is expected at   this point

这是使用 -X compile 运行时的错误堆栈：

【解决方案1】：

<testResources> should not be inside <pluginManagement>

看看maven reference

所以你应该使用

<build>
  <pluginManagement>
    <plugins>
      <!-- Use version 2.3 of the resources plugin 
       to pickup a needed filtering bugfix -->
      <plugin>                
        <artifactId>maven-resources-plugin</artifactId>
        <version>2.4.3</version>
      </plugin>
    </plugins>
  </pluginManagement>
  <!-- Enable filtering of the properties files -->
  <testResources>
    <testResource>
          <directory>src/test/properties</directory>
          <filtering>true</filtering>
    </testResource>
  </testResources>
</build>
