buildnumber-maven-plugin正在爲scmBranch返回UNKNOWN

Question

buildnumber-maven-plugin能夠從git獲取修訂號並根據the meager documentation provided它應該提供分支以及${scmBranch}屬性。但是，我所得到的全部爲UNKNOWN，屬於${scmBranch}屬性。

有什麼我需要做的從buildnumber-maven-plugin獲取分支信息嗎？

下面是我的pom.xml中的相關條目：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>buildnumber-maven-plugin</artifactId> 
    <version>1.2</version> 
    <executions> 
     <execution> 
      <phase>validate</phase> 
      <goals> 
       <goal>create</goal> 
      </goals> 
     </execution> 
    </executions> 
    <configuration> 
     <doCheck>true</doCheck> 
     <doUpdate>true</doUpdate> 
    </configuration> 
</plugin> 

<manifestEntries> 
    <Build-Branch>${scmBranch}</Build-Branch> 
    <Build-Revision>${buildNumber}</Build-Revision> 
    <Build-Timestamp>${maven.build.timestamp}</Build-Timestamp> 
</manifestEntries>

簡短的回答了buildnumber插件1.2 doesn't print git branches，所以檢查出jgit-buildnumber或maven-git-commit-id插件。

不管你多麼配置它，你不會得到一個分支出來的buildnumber插件1.2，因爲它只是在尋找SVN branch information。

反而有大量的社區貢獻git plugins for maven。

下面是一個使用所有這三個插件的實例爲例POM，您可以快速地嘗試通過mvn -f test.xml validate：
