I want to find maven native (i.e. without invoking external programs) to inject the svn version into the war manifest.
This is possible using the Build Maven Plugin using the provider svnjava:
If you need to execute a plugin on a machine without any svn in the way, you can configure mojo to use the svnjava provider.
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.0-beta-3</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>true</doCheck>
<doUpdate>true</doUpdate>
<providerImplementations>
<svn>javasvn</svn>
</providerImplementations>
</configuration>
</plugin>
</plugins>
</build>
Maven ${buildNumber}, POM.
