gradle can't download ua-parser file - gradle

Question

I'm trying to test some jenkins job seed dsls and for that I needed to download in gradle all plugins jenkins had, one of them was blueocean and in my build.gradle I've got this line
testPlugins 'io.jenkins.blueocean:blueocean:1.23.2'
and I get thrown this exception
* What went wrong:
Could not resolve all files for configuration ':compileClasspath'.
> Could not find ua_parser:ua-parser:1.3.0.
Searched in the following locations:
- https://repo.maven.apache.org/maven2/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.pom
- https://repo.maven.apache.org/maven2/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.jar
- http://repo.jenkins-ci.org/releases/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.pom
- http://repo.jenkins-ci.org/releases/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.jar
- https://jcenter.bintray.com/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.pom

I tried running with gradlew 4.8.1 and 6.0.1
I tried addint the ua-parser to build.gradle
compile group: 'ua_parser', name: 'ua-parser', version: '1.3.0'
I tried removing all gradle cache and refresh dependencies
rm -rf ~/.gradle/cache
./gradlew test --refresh-dependencies # or ./gradlew build ..
I disabled the vpn so it wasn't some firewall not allowing me to connect to the site, maybe I have some outdated gradle repository stored ? (I'm not familiar with gradle yet, so maybe something simple is escaping my sight)
EDIT 1:
I think this might be related to missing repository so tried adding new one by hand I found the https://github.com/jenkinsci/blueocean-plugin and tried add it to settings.gradle
sourceControl {
gitRepository("https://github.com/jenkinsci/blueocean-plugin.git") {
producesModule("org.gradle.blueocean:utilities")
}
}
and then referencing in build.gradle
dependencies {
...
implementation 'org.gradle.blueocean:utilities'
but doesn't seem to work, does anyone know how to add/where to search for gradle repositories (specifically with blueocean poms)

Answer 1

had to add those lines in repositories in build.gradle
repositories {
mavenCentral()
maven { url 'http://repo.jenkins-ci.org/releases/' }
maven { url 'https://mvnrepository.com/artifact/io.jenkins.blueocean' }
maven { url 'https://mvnrepository.com/artifact/ua_parser/ua-parser' }
maven { url 'https://mvnrepository.com/artifact' }
maven { url 'https://maven.twttr.com/' }
