Buildnumber maven插件在jar创建的平均时间内返回null

Question

我正在尝试将SVN修订号写入MANIFEST.MF。我添加了maven build number插件，scm连接属性到pom。我的构建号返回null。当我定义revisionOnScmFailure然后它返回测试。我正在使用Collabnet Subversion Edge 1.3.3

有些人说你必须安装SVN客户端。 Tortoise SVN安装在我的电脑上。它在Path System变量中定义。它也不是一个新项目。

我还添加了用户名和密码，在连接到scm连接时尝试了它们

<scm>
    <connection>scm:svn:https://remoteip/svn/trunk/psa</connection>
    <developerConnection>scm:svn:https://remoteip/svn/trunk/psa</developerConnection>
