We resolved the dynamic matrix support by implementing a matrix step in a
shared library,
the matrix axis are arrays that can come from files if you want
pipeline {
agent any
stages {
stage('Matrix sample') {
steps {
matrix(
agent: 'linux',
axes:[
axis('VAR_NAME_00', [ 1, 2 ]),
axis('VAR_NAME_01', [ 'a', 'b', 'c', 'd', 'e' ])
],
excludes: [
axis('VAR_NAME_00', [ 1 ]),
axis('VAR_NAME_01', [ 'd', 'e' ]),
]
) {
echo "${VAR_NAME_00} - ${VAR_NAME_01}"
}
}
}
}
}
