authentication error when publishing from gradle to nexus

Question

I am using gradle v3.4 and trying to publish a jar file to nexus. Relevant portions of build.gradle and error are copied below:

build.gradle

repositories {
    maven {
        credentials {
            username project.properties['nexusUser']
            password project.properties['nexusPassword']
        }
        url project.properties['nexusUrl']
    }
    mavenLocal()
    mavenCentral()
    jcenter()
}

I get the error below when I run gradle clean or gradle dependencies error

 Could not resolve all dependencies for configuration ':classpath'.
   > Authentication scheme 'all'(Authentication) is not supported by protocol 'file'

gradle.properties

nexusUrl="http://nexus.something.com"
nexusUser="someone"
nexusPassword="somepassword"

Answer 1

I think you miss the protocol for the url, so it assumes file:// and fails.

Answer 2

The issue was caused because I was specifying the URL and other parameters in the properties.gradle with inverted commas:

nexusUrl="http://nexus.something.com"
nexusUser="someone"
nexusPassword="somepassword"

Once I removed the inverted commas, the error went away.
When I ran gradle dependencies -s while keeping the inverted commas, I got the following output:

Exception is:

org.gradle.api.ProjectConfigurationException: A problem occurred configuring root project 'test-something'.
