$ mvn release:perform -Dtag=unilet-base-5.3.13 -DconnectionUrl=scm:svn:https://srvdevel.unimatica.lan/svn/unilet -X

I am also seeing this with Maven 3.0.3 and 3.0.4 with version plugin versions 2.2.1, 2.2.2, and 2.3.

I am also seeing the same error, but when running release:prepare; apologies if it's unrelated. I have the following setup:

Apache Maven 3.0.4 (r1232337; 2012-01-17 08:44:56+0000)
Java version: 1.6.0_31, vendor: Sun Microsystems Inc.
Default locale: en_GB, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

I'm using version 2.3.1 of the Maven Release Plugin, so my stack trace is pretty much the same except with:

Execution default-cli of goal org.apache.maven.plugins:maven-release-plugin:2.3.1:prepare failed.

@Giacomo: is this correct? [INFO] Executing: /bin/sh -c cd /tmp/${project.basedir}/target && svn --non-interactive checkout https://srvdevel.unimatica.lan/svn/unilet/tags/unilet-base-5.3.13 '/tmp/${project.basedir}/target/checkout'
Since you're running in debug mode, I'd expect to see some more feedback from the scm-provider. It looks to me like nothing is checked out, so that would explain why the plugin fails.

@Conan: I'm using Maven with equivalent environment without problems. It looks like a different issue, so please make a new issue with a small test-project, so we can reproduce your issue.

I can confirm the existence of this problem.
For me the relaease:perform from a tag fails for several plugin versions (2.1,2.3.2) except 2.0-beta-9.
The only way to get it running is therefore running:

mvn org.apache.maven.plugins:maven-release-plugin:2.0-beta-9:perform -DconnectionUrl=

As a workaround, I get a different behavior when I copy a pom.xml into the current directory.
So it seems that maven does something with the "current project" (= project in current directory),

instead of only working on the "checked out" sources in target/checkout.

Yes, I was able to get around it as well by providing a bootstrap pom.xml:

It would be nice if the default pom used by maven when there is none provided were sufficient or if the release plugin was able to check out the pom(s) from the tag specified in the release.properties.
