是否可以使用maven buildnumber插件在不进行任何scm检查的情况下生成构建号

Question

使用maven内部版本号插件时出现以下异常。在使用内部版本号插件时，是否可以禁用SCM检查？我们可以使用这个插件在非SCM版本上生成版本号吗？

执行生成时出现异常：

[ERROR] Failed to execute goal org.codehaus.mojo:buildnumber-maven-plugin:1.0:create (default) on project projectname: Execution default of goal org.codehaus.mojo:buildnumber-maven-plugin:1.0:create failed: The scm url cannot be null. -> [Help 1]

定义一个伪SCM，然后使用buildNumber项来获取顺序的内部版本号，而不是由revisionOnScmFailure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>   
            </configuration>
        </plugin>

      </plugins>
    </build>
</project>

在版本1.4中，以下工作：

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.4</version>
    <configuration>
        <revisionOnScmFailure>no.scm.config.in.pom</revisionOnScmFailure>
    </configuration>
    <executions>
        <execution>
            <id>create-timestamp-id</id>
            <phase>validate</phase>
            <goals>
                <goal>create-timestamp</goal>
            </goals>
            <configuration>
                <timestampFormat>yyyy-MM-dd HH:mm:ss.S</timestampFormat>
                <timestampPropertyName>myBuildNumberVariable</timestampPropertyName>
                <!-- formats the timestamp all together like 2016-04-04 14:17:05.123 and puts 
                    it in the ${myBuildNumberVariable} buildProperty -->
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 3

您所需要做的就是将插件封装在pluginManagement标签中

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

Answer 4

如果我没有弄错的话，以下内容曾经有效：

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.0-beta-3</version>
    <configuration>
      <buildNumberPropertyName>buildNumber.value</buildNumberPropertyName>
      <timestampPropertyName>buildNumber.timestamp</timestampPropertyName>
      <format>{0,date,yyyyMMdd-HHmm}</format>
      <items>
        <item>timestamp</item>
      </items>
    </configuration>
    <executions>
      <execution>
        <phase>validate</phase>
        <goals>
          <goal>create</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
</plugins>

Answer 5

我有一个案例，我希望同时将GIT commitId和时间戳放入属性中。这也能做到吗
当然：

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.4</version>
    <inherited>false</inherited>
    <executions>
        <execution>
            <id>commitId</id>
            <phase>validate</phase>
            <goals>
                <goal>create</goal>
            </goals>
            <configuration>
                <buildNumberPropertyName>commitId</buildNumberPropertyName>
                <shortRevisionLength>7</shortRevisionLength>
            </configuration>
        </execution>
        <execution>
            <id>buildTimestamp</id>
            <phase>validate</phase>
            <goals>
                <goal>create-timestamp</goal>
            </goals>
            <configuration>
                <timestampPropertyName>buildTimestamp</timestampPropertyName>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 6

这个工作文件对我来说很有用。只需要版本号，不需要scm。

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>buildnumber-maven-plugin</artifactId>
            <version>1.4</version>
            <configuration>
             <revisionOnScmFailure>no.scm.config.in.pom
                 </revisionOnScmFailure>
            </configuration>
            <executions>
                <execution>
                    <id>buildnumber</id>
                    <phase>validate</phase>
                    <goals>
                        <goal>create</goal>
                    </goals>
                    <configuration>
                        <format>{0,number}</format>
                        <items>
                            <item>buildNumber</item>
                        </items>
                        <doCheck>false</doCheck>
                        <doUpdate>false</doUpdate>
                        <revisionOnScmFailure>unknownbuild</revisionOnScmFailure>
                    </configuration>
                </execution>
            </executions>
        </plugin>
