[Sergiy Uvarov · Accepted solution]

I changed svn protocol to http from svn and it's working now.

Please, add some validation for 'Repository Root' field to allow only valid values.

Not all know that SvnWebclient doesn't work with svn protocol.

Thanks for helping.

[Kinto Soft]

Happy reading that it works!

I do not understand why the svn protocol is causing such problem because it is supported as well as the svn+ssh protocol.

I've looked at that line of code and it seems a configuration problem:

1. Please, look at the plug-in configuration page and review that there is not any error: sometimes the Active Objects lazy initialization is causing problems. In that case, you should vew a clear message noticing this issue and a link to fix it.

2. What is the repoId (long number) causing the problem? You can see the repoId from the browser url after clicking on the diff link. Is that repository registered and OK? (You can see the list of the registered repositories and the ID from the plugin administration page).

3. Is your issue related to diffs only? Can you explore on the repository without any problem? (the repositories can be explored from the JIRA top menu > Seubversion > SVN Web client)

4. Microsoft's style solution: re-start te plugin (disable/enable), review the plug-in configuration page (<- very important) and try the diff again. Does it fix the problem?

[Kinto Soft]

5. It might be also caused by a missing writing privileges in the system temp directory for the user running the JIRA process. The bundled web client for Subversion uses and advanced feature in order to cache commits messages.

[Sergiy Uvarov]

1. I checked the plugin configuration, no errors

2. repoId = 1, and the repository with such id exists. I imported this

repository from the Atlassian's JIRA Subversion plugin configuration.

3. The same exception when accessing repository from Subversion->SVN Web client

4. After Disabling/Enabling there are erros on Subversion Configuration page:

The scheduled interval for the Indexation process might have lost its value.

The database configuration cannot be read because the lazy initialization of the Active Objects.

After pressing Intialize Active Objects errors were gone.

5. Permissions are OK.

Is it possible to get source of the plugin? I can debug it.

[Kinto Soft]

The 1.x version is opensource, but I'm affraid that the 2.x not, and the Web Client for Subversion was integrated in the 2.x version...

Despite several users have reported that importing the configuraton works nicely, it might exists some configuration issue in your case:

6. Might you edit the repository configuration and review that everything is OK there? What access protocol are you using to access to Subversion?

7. If step 6 is OK, please then try by removing the repository from the configuration and by adding it again by hand. As the fork does not require any further repository diff URL (they are automatically configured when a new repositorty is added) and it also provides default values for most of the fields, adding a new repository will take you few seconds: you have to provide only the repository root url the username and the password and the private key file in the case you are using svn+ssh or ssl authentication.
