properties-maven-plugin:加载属性文件时出错 [英] properties-maven-plugin: Error loading properties-file

问题描述

我想将pom.xml中的所有属性提取到属性文件中.这些是常用属性，例如依赖项版本，插件版本和目录. 我正在使用properties-maven-plugin，但是它无法按我想要的方式工作.

I want to extract all the properties from my pom.xml into a properties-file. These are the common properties like dependency-versions, plugin-versions and directories. I'm using the properties-maven-plugin, but its not working as i want it to.

我的pom.xml的必要部分:

The essential part of my pom.xml:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>properties-maven-plugin</artifactId>
  <version>1.0-alpha-1</version>
  <executions>
    <execution>
      <phase>initialize</phase>
      <goals>
        <goal>read-project-properties</goal>
      </goals>
      <configuration>
       <files>
          <file>${basedir}/pom.properties</file>
        </files>
      </configuration>
    </execution>
  </executions>
</plugin>

现在，当我运行"mvn properties:read-project-properties"时，出现以下错误:

Now when i run "mvn properties:read-project-properties" i get the following error:

[INFO] One or more required plugin parameters are invalid/missing for 'properties:read-project-properties'

[0] Inside the definition for plugin 'properties-maven-plugin' specify the following:

<configuration>
  ...
  <files>VALUE</files>
</configuration>.

pom.properties文件位于与pom.xml相同的目录中. 我该怎么做才能让properties-maven-plugin读取我的properties-file?

The pom.properties-file is located in the same dir as the pom.xml. What can i do to let the properties-maven-plugin read my properties-file?

编辑

我在 http://jira.codehaus.org/browse/MOJO-1523上提出了一个问题. 它已被关闭为不是bug"，原因是:

I filed an issue at http://jira.codehaus.org/browse/MOJO-1523. It has been closed as "not a bug", the reason is:

这是设计使然.项目定义 必须是独立的，否则 如果被引用，则不再完整 从其他地方作为 传递性部门.

It's by design. The project definition has to be self-contained, otherwise it is no longer complete if it is refered from elsewhere as part of the transitive deps.

请参见这里，了解使用Ant Tasks的变通方法，这使该用例成为可能
