maven - 属性-maven-plugin : The parameters 'files' for goal . .. 丢失

Question

我正在使用 Maven 3.0.3。我正在尝试从属性文件中测试读取属性(这是更大努力的一部分，我想首先正确处理这部分)。我的 pom.xml 文件中有这个...

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>maven-properties-plugin</artifactId>
    <version>1.0</version>
    <configuration>
      <files>
        <file>${basedir}/build.properties</file>
      </files>
    </configuration>
  </plugin>

但遗憾的是，运行“mvn properties:read-project-properties”失败并出现以下错误。我需要如何重新配置​​我正在做的事情？ - 戴夫

我认为您混淆了插件 Artifact 设置。正确的 Artifact 标识符是

<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
