Hello,

We're trying to use the Maven Release Plugin with the Jazz SCM Provider, however we're having a few problems.

We're getting Exit Code 53 when trying to execute the below command:

mvn -B -Dresume=false -DworkingDirectory=D:/tmp/maven -DignoreSnapshots=true release:prepare release:perform

as per https://maven.apache.org/scm/maven-scm-providers/maven-scm-provider-jazz/releases.html

Below is the debug output from Maven.

I tried adding "-DsuppressCommitBeforeTag=true" to the command but instead get the error "Cannot perform a remote tag or branch without committing the working copy first.".

Does anyone have any ideas as to why this might be happening?

This is normal. The meaning of exit code 53 is "Indicates that a deliver succeeded, but there were no changes to deliver to the repository". It matches the rest of the messages (no changes to deliver).

The Maven build is marked as 'Failed' when the error appears, which causes our associated Jenkins job to fail as well. Is there a way to mark it as successful or to skip the unsuccessful SCM commands?

Donald Nong commented Jan 11 '17, 11:34 p.m.

Probably Maven Build should treat exit code 52 and 53 similar to 0? Usually, a command will only return 0 as a successful signal, but apparently scm returns 52 and 53 as successful signal as well - you cannot say that they are "unsuccessful SCM commands".
