maven scm:checkin error - maven

Question

My maven script generates a laconic "error 1", and I am a bit at a loss as to how to extract the root cause from the huge output.
Could you help me in isolating said root cause for this error?
Here is the command I used:
mvn scm:checkin -Dmessage="check in"
error 1.

Answer 1

The important part is:
svn: 'E:\workspace\mtest' is not a working copy
So make sure your Maven task execute itself in an SVN working copy.

Answer 2

The directory you execute the scm:checkin from needs to be a svn working directory, which means you should have a ".svn" in that directory with the correct contents inside(the .svn is the svn admin directory which contains the pristine files downloaded).
Check if your .svn directory exists or if it's empty ( i found out that when I used "includes=*" in the checkout execution configuration, maven wipes out the .svn directory), which caused the subsequent scm:checkin to fail. And in your case, since you are using "includes=src/*,pom.xml", your .svn directory might not even exist.
To fix this, you can define execution for checkout in the maven-scm-plugin first (without using includes), then define a separate execution for add/check. And here's a pom.xml to do scm:checkout, curl download, then scm:checkin
