hi

The SVN_REVISION environment variable does not seem to be set when using @HEAD in a Subversion URL.

Try to run the "echo.properties" Ant target below using Hudson.
---
<?xml version="1.0" encoding="windows-1252" ?>
<project name="SomeSVNRevisionProject" default="" basedir=".">
	<property environment="env"/>

	<target name="echo.properties">
		<echo message="env.SVN_REVISION = ${env.SVN_REVISION}"/>
	</target>
</project>
---

Using a Subersion URL without @HEAD suffix the console output is:
---
Started by user anonymous
Updating file:///D:/temp/some-repository/trunk revision: Jun 16, 2013 7:27:30 PM depth:infinity ignoreExternals: false
At revision 2
no change for file:///D:/temp/some-repository/trunk since the previous build
[temp] $ cmd.exe /C '"C:\oracle\jdevstudio111230-mw\jdeveloper\ant\bin\ant.bat -buildfile D:/temp/build.xml echo.properties && exit %%ERRORLEVEL%%"'
Buildfile: D:\temp\build.xml

echo.properties:
     [echo] env.SVN_REVISION = 2

BUILD SUCCESSFUL

Using a Subersion URL with @HEAD suffix the console output is:

no change for file:///D:/temp/some-repository/trunk since the previous build

echo.properties:
     [echo] env.SVN_REVISION = ${env.SVN_REVISION}

I would expect the SVN_REVISION environment variable to always be set, regardless the use of @HEAD in a Subversion URL.

(seems related to https://issues.jenkins-ci.org/browse/JENKINS-10942 )

many thanks
