Inside .gitlab-ci.yml we define a variable (which is just the artifactId name for the project) ARTIFACT_ID: myMicroservice-1
This variable ARTIFACT_ID is sent to a general microservice which has all the scripts to publish/deploy docker, etc.
How can I read this variable direct from POM file?
pom:
<artifactId>myMicroservice-1</artifactId>
.gitlab-ci.yml:
variables:
SKIP_UNIT_TESTS_FLAG: "true"
ARTIFACT_ID: myMicroserverName
IS_OSL: "true"
KUBERNETES_NAMESPACE: test
Here is how we do it.
Value is extracted from the pom.xml based on its XPath.
We use xmllint tool from libxml2-utils, but there are various other tools for that.
Then value is saved as an environment variable in a file, which is passed to further GitLab jobs as artifact.
stages:
- prepare
- build
variables:
VARIABLES_FILE: ./variables.txt # "." is required for sh based images
POM_FILE: pom.xml
get-version:
stage: prepare
image: ubuntu
script:
- apt-get update
- apt-get install -y libxml2-utils
- APP_VERSION=`xmllint --xpath '/*[local-name()="project"]/*[local-name()="version"]/text()' $POM_FILE`
- echo "export APP_VERSION=$APP_VERSION" > $VARIABLES_FILE
artifacts:
paths:
- $VARIABLES_FILE
build:
stage: build
image: docker:latest
script:
- source $VARIABLES_FILE
- echo "Here use $APP_VERSION as you like"
This is the script to grab information from pom, in this case, artifactId:
- export myARTIFACT_ID=$(mvn exec:exec -q -Dexec.executable=echo -Dexec.args='${project.artifactId}')
- if [[ "$myARTIFACT_ID" == *finishWithWhatEverName]]; then export myVariable="false"; else export myVariable="true";
Then you can use myVariable to whatever you want.
I tried Angel's solution, but got an error:
/bin/bash: line 87: mvn: command not found
Finally I succeeded when I used the following to extract the tag value:
- export ARTIFACT_ID=$(cat pom.xml | grep "<artifactId>" | head -1 | cut -d">" -f2 | cut -d"<" -f1 | awk '{$1=$1;print}')
