java - 使用属性值设置 Maven 父版本？

Question

您好，我正在尝试将 Maven 中的父版本设置为属性上定义的版本，但它不起作用

这是我写的

<parent>
    <groupId>com.me.android</groupId>
    <artifactId>me-android</artifactId>
    <version>${tools.version}</version>
    <relativePath>../pom.xml</relativePath>
</parent>
 <properties>
      <tools.version>1.0.0-SNAPSHOT</tools.version>
 <properties>

它不起作用，我必须手动输入版本值而不是使用属性值。

下方错误

这是一个已知问题。不幸的是，您不能参数化父部分。

Maven does not allow variables to be specified in any of the elements within the parent element. When installing or deploying a project Maven will copy the pom.xml for the project into the local or remote repository. No changes are made to the file.

有关详细说明和可能的解决方法，请参阅此 JIRA 问题:

http://docs.codehaus.org/display/MAVEN/Automatic+Parent+Versioning

虽然这个错误是在 2008 年记录的，但不幸的是它仍然是一个当前问题。查看列出的相关问题，尤其是:

http://jira.codehaus.org/browse/MNG-624

这是最近更新的。似乎近期没有补救措施，但您可以尝试解决方法。
