gitlab trigger pipeline for specific branches only

I have configured gitlab ci/cd pipeline for my project. So I have used base template which has 2 stages, build & package. Build stage builds project and create jar file and package stage create image and store it in container registry. And .gitlab-ci.yml file has been created. Below is file

image: docker:latest
services:
  - docker:dind

stages:
  - build
  - package

build:
  image: gradle:5.6.1-jdk11
  stage: build
  script:
    - gradle clean build -x test
  artifacts:
    paths:
      - build/libs/*.jar

package:
  stage: package
  script:
    - docker build -t registry.gitlab.com/my-project/sample .
    - docker login -u $CI_DOCKER_USERNAME -p $CI_DOCKER_PASSWORD registry.gitlab.com
    - docker push rregistry.gitlab.com/my-project/sample

When we want to add new functionality we obviously create new branch and since this file exist in the new branch too, build is getting triggered. But I dont want to trigger a build for all the branches. I want to trigger only development and master. Is there anyway we can do that at project level instead of adding only in each stage

The only way to limit when jobs are created is by using only/exceptin the .gitlab-ci.yml file.

To not have to write so much text, you can use extends and also sometimes yaml anchors. More info here:

https://docs.gitlab.com/ee/ci/yaml/#extends

and here:

https://docs.gitlab.com/ee/ci/yaml/#anchors

An example of how extends can be used:

image: docker:latest
services:
  - docker:dind

.only-master-and-develop:
  only:
   - master
   - development

stages:
  - build
  - package

build:
  extends: .only-master-and-develop
  image: gradle:5.6.1-jdk11
  stage: build
  script:
    - gradle clean build -x test
  artifacts:
    paths:
      - build/libs/*.jar

package:
  extends: .only-master-and-develop
  stage: package
  script:
    - docker build -t registry.gitlab.com/my-project/sample .
    - docker login -u $CI_DOCKER_USERNAME -p $CI_DOCKER_PASSWORD registry.gitlab.com
    - docker push rregistry.gitlab.com/my-project/sample

(I haven't tested this file, please let me know if there's something wrong with it.)

You should specify the target branch using via $CI_COMMIT_BRANCH == "<your_branch_name>".

rules:
    - if: '$CI_PIPELINE_SOURCE == "push" && $CI_COMMIT_BRANCH == "master"'
      something regarding the project..

    - if: '$CI_PIPELINE_SOURCE == "web" && $CI_COMMIT_BRANCH == "development"'
      something regarding the project..

I hope above example can help anyone!

Also here is the documentation for these types of questions.
