Trouble running ./gradlew build

Question

Gradle cannot build to an unknown error

I attempted to build an application by typing the command ./gradelw build on the terminal. It throws an error message that Build file '/home/muhammad/bootcamp-projects/java-app/build.gradle'

line: 28

A problem occurred evaluating root project 'my-app'. Could not get unknown property 'repoUser' for root project 'my-app' of type org.gradle.api.Project.

this is the code :

Answer 1

You do not say where you defined repoUser and repoPassword .

If these are defined as environment variables, then you can use:

username = System.getenv('repoUser')                                                           
password = System.getenv('repoPassword')
