maven-2 - 我的profiles.xml有什么问题？

Question

这是profiles.xml的mvn的一部分:

<profilesXml>
  <profiles>
    <profile>
      <id>production</id>
      <build>
        <plugins> .. </plugins>
      </build>
    </profile>
  </profiles>
</profilesXml>

这是 mvn所说的:

Caused by: org.codehaus.plexus.util.xml.pull.XmlPullParserException: 
Unrecognised tag: 'build' (position: START_TAG seen ...</id>\n
        <build>... @32:20)

怎么了

Answer 1

错误消息为您提供了正确的反馈，您不能在外部配置文件中指定<build/>部分，而只能指定<properties>，<pluginRepositories>和<repositories>。从Introduction to Build Profiles:

Profiles in external files

Profiles specified in external files (i.e in settings.xml or profiles.xml) are not portable in the strictest sense. Anything that seems to stand a high chance of changing the result of the build is restricted to the inline profiles in the POM. Things like repository lists could simply be a proprietary repository of approved artifacts, and won't change the outcome of the build. Therefore, you will only be able to modify the <repositories> and <pluginRepositories> sections, plus an extra <properties> section.

The <properties> section allows you to specify free-form key-value pairs which will be included in the interpolation process for the POM. This allows you to specify a plugin configuration in the form of ${profile.provided.path}.

如果您的摘录来自一本书，则该书应该是固定的。
