I try to run mvn release:prepare (of course, after release:clean), and I get an error:
Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.5:prepare (default-cli) ...: Error writing POM: D:\\pom.xml (Access is denied)
Caused by: java.io.FileNotFoundException: D:...\pom.xml (Access is denied)
The problem: The file IS IN THE specified location, but it is write-protected (because it is under SCM). All poms must be checked-in, otherwise I get an error in earlier stage (check-poms phase). So pom must be checked-in, i.e. write-protected, hence I get "access denied" exception, and it does not make any sense!
After downoading the maven sources scm-plugin and release-plugin), I tried to find something but unfortunately could not find a reason for this exception. Maybe I am missing something, so I post it here, maybe someone can shed some light.
I've added logs in several points in the code (in DefaultReleaseManager, so I can see the phases), re-built and I see that it fails on phase called 'rewrite-poms-for-release', which is the phase where maven tries to change my poms into release, and check them in again. But the thing is that these poms are under source-control, so they are read only. So the plugin cannot write to these poms, so it returns the error 'access denied'.
Tried to see if there is something in the relevant class, class RewritePomsForReleasePhase extends AbstractRewritePomsPhase, but found nothing. Tried to run it with -X, so i got the relevant exception (see below).
I work with maven-release-plugin:2.5, maven-scm-plugin:1.9, the provider is TFS (but I do not see how it is relevant for my error, since it does not fail in the 'provider' or in the scm-plugin.)
UPDATE:
Just tried to reproduce with maven-release-plugin:2.1, which I know works for sure (with maven-scm:1.4). I get the same error. So I guess something in my configuration is incorrect... Maybe there are experts here that can help? Maybe it is related to the maven-scm-plugin?

It appears to be a bug in the maven-scm-provider-tfs. Meaning, the TFS support for maven-scm-plugin is not full.
I've opened a JIRA item [SCM-752] for this, and a fix was suggested. It will be released in the next release (1.10) of maven-scm-plugin.
