I want to pass values of environment variables to Maven via command line.
How to do?

Attempts:

  • mvn liquibase:update -Dliquibase.url=$DB_URL: Maven executes, but the value is not passed

  • mvn liquibase:update -Dliquibase.url=${DB_URL}: Maven executes, but the value is not passed

  • mvn liquibase:update -Dliquibase.url=${env.DB_URL}: bash error:

-bash: -Dliquibase.url=${env.DB_URL}: bad substitution

    The first and second methods are equivalent, and I can’t imagine why they didn’t work

  • @Jeffersonquesado I think is right. The problem is when the base connect to the bank. It is not passing the user. I thought it was a call problem but it’s not. I’ll answer

My fault.

The command mvn liquibase:update -Dliquibase.url=$DB_URL works.
I thought it did not work because Liquibase was not receiving the parameters, but it is for another problem.
