properties-maven-plugin：目标的参数“文件”丢失......

Question

我正在使用 Maven 3.0.3。我正在尝试测试从属性文件中读取属性（这是更大努力的一部分，我想先把这部分做好）。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

Answer 1

我认为您混淆了插件工件设置。正确的工件标识符是

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

见：Plugin Homepage

Answer 2

1. 更新到当前插件版本1.0-alpha-2
2. 确保build.properties 文件存在于${basedir}
3. 要么：
   • 使用mvn properties:read-project-properties 调用mvn 时指定目标
   • 或将目标添加到pom.xml

例如pom.xml:

<build>
  <plugins>
  ...
  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>properties-maven-plugin</artifactId>
    <version>1.0-alpha-2</version>
    <executions>
      <execution>
        <phase>initialize</phase>
        <goals>
          <goal>read-project-properties</goal>
        </goals>
        <configuration>
          <files>
            <file>${basedir}/build.properties</file>
          </files>
        </configuration>
      </execution>
    </executions>
  </plugin>
  ...
  </plugins>
</build>

Answer 3

您确定您的build.properties 文件在您的${basedir} 中吗？

${basedir}代表包含pom.xml的目录

您可以参考http://docs.codehaus.org/display/MAVENUSER/MavenPropertiesGuide
