I have 1 project set up to trigger builds on SVN checkins. When a build is triggered in this way it sometimes immediately fails with the following exception. This doesn't happen if I manually run the build by clicking Run.

This still happens (some of the time) after upgrading the Subversion client to 1.4.0

Please ensure log4j config xml (teamcity-log4j) is up-to-date on the server and attach svn.log file from the server logs directory after the next fail.

teamcity-log4j.xml should contains:
<appender name="SVN.LOG" class="org.apache.log4j.RollingFileAppender">
<param name="file" value="${teamcity_logs}svn.log"/>

<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ABSOLUTE}] %6p - %30.30c - %m %n"/>
</layout>
</appender>

<category name="javasvn.output">

<priority value="ALL"/>
<appender-ref ref="SVN.LOG"/>

</category>

Thanks!

I've configured logging as described above, but it doesn't seem to be happening anymore. I'll include the log as soon as the error re-occurs.

I am also seeing these errors, but within IDEA, not TeamCity.

In my case, it's happening when I try to merge changes from one branch into another. (It successfully processes some number of files, then bombs out with the "malformed network data" error.) I see no such errors when using theTortoiseSVN client.

I'm running IDEA 6.0.1 on WIndows XP. Is there any additional information you would like from me?

I've exatly the same issue on the latest EAP TeamCity. I had to upgrate since the old one has stopped getting sources from svn.

I've tried to put "<appender name="SVN.LOG..." but it only produces an empty svn.log file.

Messages in the TeamCity log are:

...
[2006-10-31 11:22:29,377] INFO - javasvn.output - svn: Malformed network data, string length expected
[2006-10-31 11:22:29,393] INFO - javasvn.output - svn: Malformed network data, number expected

...

I've tried to replace svn.jar by a version from the 1.0 relase but then it stops gettings sources from svn at all.

Subversion on the client and server is 1.3.2 r19776.

TeamCity Version 1.0.1 (build 1712)

Please make svn log all messages:

<category name="javasvn.output">

<priority value="ALL"/>
<appender-ref ref="SVN.LOG"/>

</category>

It seems that file contains everything what is required, but the svn.log is still empty. What did I miss?

Seems logs go to the main log file (team-city.log). Does it contains lines starting with "svn.output"?
Add
<filter class="jetbrains.buildServer.log.CategoryFilter">
<param name="DenyCategory" value="javasvn.output"/>
</filter>
into ROLL appender to avoid this.

Olesya, sorry I did recognize it, it is the same what I've posted above (svn.output).

See a bit more information with exception in the log file.

This is a known issue when SVN server is updated to version 1.4, but older clients are used. The issue is JavaSVN. Just update to version 1.1.0 ( http://svnkit.com/download/index.php ) and it will work.

Just an update. Use SVNKit v. 1.1.2

This is fixed in the more or less recent version SVNKit (already used by TeamCity).
