Is it possible to use maven buildnumber plugin to generate build number without any scm check?

Question

Getting the following exception while using maven build number plugin. Is it possible to disable SCM check while using the build number plugin? Can we use this plugin to gen

Answer 1

I had the case, that I wanted a GIT commitId and a timestamp to be put into properties, both at the same time. Can this be done as well?
Of course:

<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>

This work file for me. Might help with just version number and no need of 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>

Answer 3

The following used to work, if I'm not mistaken:

  <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 4

All you need to do is to enclose your plugins within pluginManagement tag

<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 5

Define a dummy SCM and then use buildNumber item to get sequential build number instead of value defined by revisionOnScmFailure property.

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>

With version 1.4 the following works:

<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>
