I'm using SVN, Maven 3.0.3 on the latest version of Jenkins and the Maven Release plugin. I'm trying to use the Maven release plugin (through Jenkins) do a dry run and so am executing the options …

Executing Maven: -B -f /scratch/jenkins/workspace/myproject/myproject/pom.xml -DdevelopmentVersion=53.0.0-SNAPSHOT -DreleaseVersion=52.0.0 -Dusername=***** -Dpassword=********* -DskipTests -P prod -Dresume=false -DdryRun=true release:prepare

But the dry run is dying with the error below …

My SVN checkout method is set to "Always checkout a fresh copy" and I have a snapshot version in question in my snapshot repository, but not in my release repository. Is there a way I can get the "reactor projects list" to look at my snapshot repo?

Edit: I'm including the snippet of my pom where the project gets its version -- it inherits it from a parent

 <parent> <artifactId>subco</artifactId> <groupId>org.mainco.subco</groupId> <version>52.0.0</version> </parent>

You're trying to release an artifact that's not a snapshot. That means your artifact's version number is something like 3.0.3. That version number implies its already been released. You can't release a release. There would be no changes in between and therefore no point.

You're only supposed to release SNAPSHOT versions. That means your version number would be like 3.0.3-SNAPSHOT.

I added how I'm getting my version -- I'm inheriting it from a parent pom. Sadly if I change the version to include "-SNAPSHOT," I get the error, "Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.0:prepare (default-cli) on project myproject: Can't release project due to non released dependencies"
@Dave I think you'll have to make the parent a snapshot, too.
I may need to open a second SO question about this, but the parent pom does have a SNAPSHOT version, although it is "53.0.0-SNAPSHOT" (instead of what I'm trying to inherit from, 52.0.0-SNAPSHOT). Were you referring to changing the version in the parent pom?
I think the error message is not self explanatory unless you know what "reactor projects list" means. Thanks for the very clear answer.
It would be so much easier to understand if they would just add a message like "You can't release a release. ". The message that they come up with is "You don't have a SNAPSHOT project in the reactor projects list." ... Who will ever interpret this message the way it is supposed to?

Jenkins workspace is not cleanup or you have FINAL version inside pom.xml. Jenkins has check-out strategy for cleaning up workspace.

More: Maven release plugin - SNAPSHOT project needed

Check-out Strategy options:

  • Emulate clean checkout by first deleting unversioned files/ignored files, as well as files/directories ignored by svn:ignore, then execute svn update.
  • Always check out fresh copy
  • Use svn update as much possible, with svn revert before update

What do you mean by "Jenkins has options for cleaning up workspace"? Where are these options? Are you talking about the workspace cleanup plugin for Jenkins?
Check-out Strategy options
for me this was the case, after clearing jenkins workspace it worked.

Bump Up your Project POM file for from the previously built code base to a new version.

1.0.1-SNAPSHOT<version>1.0.1-SNAPSHOT</version>

Changing the check-out strategy to "Emulate clean checkout by first deleting unversioned files/ignored files, then svn update" did the trick for me.
