I do not know what wrong i did.
The process I am following is :-
- checking out from svn
- cd to that checkout directory
- Executing my necessary svn commands
- Executing
mvn release:clean - Executing
mvn release:prepare - Executing
mvn release:perform, but it fails.
Thanks in Advance.

Developer connection from:
<scm>
<developerConnection>scm:svn:https://svn.mycompany.com/repos/myapplication/trunk/mycomponent/</developerConnection>
</scm>
should point to your maven project that you want to release.
Also, arbitrarily location can be used for release tag in plugin configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-release-plugin</artifactId>
<version>2.5.2</version>
<configuration>
<tagBase>https://svn.mycompany.com/repos/myapplication/releases</tagBase>
</configuration>
</plugin>
One has to read usage page properly (which I also didn't do) and everything will work fine.
Still, I believe that plugin logging should give more precise information about the problem (or possible problems).
