maven - 是否可以使用maven buildnumber插件生成内部版本号而无需任何scm检查？

Question

使用Maven内部版本号插件时出现以下异常。使用内部版本号插件时是否可以禁用SCM检查？我们可以使用此插件在非SCM版本中生成版本号吗？

进行构建时发生异常:

定义一个虚拟SCM，然后使用buildNumber item来获取顺序的内部版本号，而不是由versionOnScmFailure属性定义的值。

pom.xml:

<project ...>

    <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>

    <build>
      <plugins>

        ...

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>buildnumber-maven-plugin</artifactId>
            <version>1.1</version>
            <executions>
            <execution>
                <id>buildnumber</id>
                <phase>validate</phase>
                <goals>
                <goal>create</goal>
                </goals>
            </execution>
            </executions>
            <configuration>
                <format>{0,number}</format>
                <items>
                <item>buildNumber</item>
                </items>                    
                <doCheck>false</doCheck>
                <doUpdate>false</doUpdate>
                <revisionOnScmFailure>unknownbuild</revisionOnScmFailure>
