I have 2 properties in gradle.properties as

Host=localhost  
Port=8888

And I want to use it my Junit test.  
How can I achieve this?

The gradle Test task offers a systemProperty method to create jvm system properties.  
[https://docs.gradle.org/current/dsl/org.gradle.api.tasks.testing.Test.html](https://docs.gradle.org/current/dsl/org.gradle.api.tasks.testing.Test.html)

```
test {
systemProperty 'host', project.host
systemProperty 'port', project.port
}

```

THen in your java Unit test

```
System.getProperty("host")

```

If you have tons of them, you can use

```
test {
systemProperties = project.properties
}

```

to copy all your gradle project properties to the Test Jvm system properties

test {  
systemProperty ‘host’, project.host  
systemProperty ‘port’, project.port  
}

This is working for me.

How can I put all in one file like project.proiperties or gradle.properties and use it with systemProperties?

The following should work. See [ConfigSlurper API](http://docs.groovy-lang.org/latest/html/gapi/groovy/util/ConfigSlurper.html) or [example](http://mrhaki.blogspot.fr/2009/10/groovy-goodness-using-configslurper.html)  
test {  
systemProperties = new ConfigSlurper().parse(file('gradle.properties).toURL()).flatten()  
}
