maven release plugin fails second time on gitlab-CodePudding

I setup a pipeline on gitlab but I get a weird error "You don't have a SNAPSHOT project in the reactor projects list"

I'm just trying to deploy a java spring boot. Below the pom.xml (only what's relevant)

<name>Project Phoenix - Base</name>
<groupId>com.gfs</groupId>
<artifactId>phoenix</artifactId>
<version>1.12-SNAPSHOT</version>
<packaging>pom</packaging>

...

<scm>
    <developerConnection>scm:git:${project.scm.url}</developerConnection>
    <url>[email protected]:"myuser"/phoenix.git</url>
    <tag>HEAD</tag>
</scm>
....
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <version>${maven.release.plugin}</version>
            <configuration>
                <scmDevelopmentCommitComment>@{prefix} prepare for next development iteration [skip ci]</scmDevelopmentCommitComment>
            </configuration>
        </plugin>

My gitlab-ci.yml looks like this:

workflow:
  rules:
    - if: $CI_COMMIT_TAG
      when: never
    - if: $CI_COMMIT_BRANCH == 'master'

variables:
  MAVEN_OPTS: "-Dmaven.repo.local=$CI_PROJECT_DIR/.m2/repository"
  MAVEN_CLI_OPTS: "-s settings.xml --batch-mode --errors --fail-at-end --show-version"
  MAVEN_IMAGE: maven:3.8.5-openjdk-17-slim

services:
  - docker:dind

stages:
  - build
  - release

cache:
  paths:
    - .m2/repository/
    - target/

build-job:
  image: $MAVEN_IMAGE
  stage: build
  script:
    - echo "Building $MODULE"
    - mvn clean package -B $MAVEN_CLI_OPTS
 
release-job:
  image: $MAVEN_IMAGE
  stage: release
  tags:
    - local-runner
  before_script:
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
    - eval $(ssh-agent -s)
    - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
    - mkdir -p ~/.ssh
    - chmod 700 ~/.ssh
    - '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
    - apt-get update -qq
    - apt-get install -qq git
    - git config --global user.email "hidden"
    - git config --global user.name "hidden"
    - git checkout -B "$CI_COMMIT_REF_NAME"
  script:
    - echo "Creating the release"
    - mvn $MAVEN_CLI_OPTS clean deploy release:prepare release:perform
  only:
    - master

After I push, gitlab starts a pipeline on the commit which is successful and it deploys in the gitlab package registry the snapshot and the release. However, there are other 2 pipeline starting [maven-release-plugin] which it seems it does the same things but it fails:

First it says:

Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded. (use "git pull" to update your local branch)

Then it says: You don't have a SNAPSHOT project in the reactor projects list

$ git checkout -B "$CI_COMMIT_REF_NAME"
Switched to and reset branch 'master'
Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded.
  (use "git pull" to update your local branch)
$ echo "Creating the release"
Creating the release
$ mvn $MAVEN_CLI_OPTS clean deploy release:prepare release:perform

The third and last pipeline is [maven-release-plugin] prepare for next development iteration [skip ci] which is Skipped..

Does anybody know what it should happen, why does it complain on the snapshot?

Thanks

CodePudding user response：

Basically, if not that error you would run in infinite loop :) The release:prepare performs the following steps:

Check that there are no uncommitted changes in the sources
Check that there are no SNAPSHOT dependencies
Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
Transform the SCM information in the POM to include the final destination of the tag
Run the project tests (preparation goals) against the modified POMs to confirm everything is in working order
Commit the modified POMs
Tag the code in the SCM with a version name (this will be prompted for)
Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
Eventually run completion goal(s) against the project (since 2.2) Commit the modified POMs

So, upon completion of your CI pipeline you are getting two new commits into master branch:

[maven-release-plugin] prepare for next development iteration
[maven-release-plugin] prepare release XXX

which in turn triggers your CI pipeline again, you just need to disable pipeline triggering for specific CI_COMMIT_MESSAGE (or setup scmReleaseCommitComment, which actually looks not so good as well as scmDevelopmentCommitComment)
