maven之Jenkins 和 maven-buildnumber-plugin

我正在使用 maven-buildnumber-plugin版本 1.0-beta-4。这在从 Subversion checkout 的项目上工作正常，但在 Jenkins 中失败。

我认为这个问题是由于 Jenkins 以某种方式删除了 .svn 文件夹造成的。

我猜错了。这是我得到的错误:

我忽略了这一点:

Provider message: 
The svn command failed. 
Command output: 
/bin/sh: svn: command not found 
 
mojoFailed org.codehaus.mojo:buildnumber-maven-plugin:1.0-beta-4(default) 

机器上没有安装svn客户端，那才是真正的麻烦源。

请您参考如下方法:

错误信息显示命令svn没有安装在构建机器上。您可以使用 javasvn 作为具有此配置的 providerImplementation:

   <plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>buildnumber-maven-plugin</artifactId> 
    <version>1.0</version> 
    <executions> 
      <execution> 
        <phase>validate</phase> 
        <goals> 
          <goal>create</goal> 
        </goals> 
      </execution> 
    </executions> 
    <configuration> 
      <doCheck>true</doCheck> 
      <doUpdate>true</doUpdate> 
      <providerImplementations> 
        <svn>javasvn</svn> 
      </providerImplementations>           
    </configuration> 
  </plugin> 

参见 http://mojo.codehaus.org/buildnumber-maven-plugin/using-svnjava.html

如果您需要一个特定版本的 Subversion(我们在这里仍然使用 1.5)，您也可以固定到一个特定版本的 svnkit:

    <dependency> 
        <groupId>org.tmatesoft.svnkit</groupId> 
        <artifactId>svnkit</artifactId> 
        <version>1.2.3.5521</version> 
    </dependency>
