maven buildnumber插件错误scm url不能为null

Question

我是Maven的新用户，并且很难获得buildnumber-maven-plugin来做我期望的事情。本质上，我希望maven构建我的项目并创建结果的JAR文件，并在manifest.mf文件中设置内部版本号。我将在下面包含我的大部分pom.xml文件。我已经发布了一个相关的问题，但这个问题是关于一个不同的问题！

当我运行mvn clean编译包时，我看到以下错误：

[ERROR] Failed to execute goal org.codehaus.mojo:buildnumber-maven-plugin:1.4:create (buildnumber) on project xcase: Execution buildnumber of goal org.codehaus.mojo:buildnumber-maven-plugin:1.4:create failed: The scm url cannot be null. -> [Help 1]

我已将doCheck和doUpdate都设置为false，因此不知道SCM涉及的原因。我的解决方法是添加一些虚拟SCM配置，但这感觉很笨重。还有更好的方法吗？

  <scm>
    <connection>scm:svn:http://127.0.0.1/dummy</connection>
    <developerConnection>scm:svn:https://127.0.0.1/dummy</developerConnection>
    <tag>HEAD</tag>
    <url>http://127.0.0.1/dummy</url>
  </scm>

这是我的pom.xml文件的构建部分：
