I do not know what wrong i did.

The process I am following is :-

1. checking out from svn
2. cd to that checkout directory
3. Executing my necessary svn commands
4. Executing mvn release:clean
5. Executing mvn release:prepare
6. Executing mvn release:perform , but it fails.

Thanks in Advance.

Answer 1

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).
