I have a dynamically generated list of dependencies.

```gradle
def myRequirments = ['jar1', 'jar2', 'jar3']

```

I would like to create a maven dependencies on these jars, something like:

```gradle
buildscript {
    repositories {
            myRequirments.each {
            maven { url it }
            }
    }
}

```

How would I do this?

I don’t understand what you are trying to achieve. Can you elaborate?

Peter, I had a bit of a brain glitch when I wrote this post. What I meant to say is that I want to add multiple repository urls.

```gradle
def myRepos = ['http://repo1', 'http:repo2', 'http:repo3']

```

```gradle
buildscript {
    repositories {
            myRepos.each {
               maven { url it }
            }
    }
}

```

This should work fine as long as ‘myRepos’ is declared within ‘buildscript { … }’. The ‘buildscript’ block is (very) special in that it cannot refer to anything that’s declared outside. A good mental model to have is to consider it a separate build script that gets evaluated before the remainder of the build script.

When I do the following I receive and warning and it seems that the repositories are not being added to the project.

```gradle
buildscript {
    repositories {
            ['file:C:\project\subProjectOne\libs',
             'file:C:\project\subProjectTwo\libs',
             'file:C:\project\subProjectThree\libs',
            ].each {
               maven { url it }
            }
    }
}

```

```gradle
Converting class org.gradle.api.internal.artifacts.repositories.DefaultMavenArtifactRepository_Decorated to File using toString() method has been deprecated and is scheduled to be removed in Gradle 2.0. Please use java.io.File, java.lang.String, java.net.URL, or java.net.URI instead.

The use of ‘it’ is wrong. You need to specify an explicit closure parameter after ‘each’.

Thanks for the help Peter!

The last problem I had was a simple coding error. There was a space in between the file and the url. The array I was passing to the each looked like:

```gradle
['file: C:\project\subProjectOne\libs',
             'file: C:\project\subProjectTwo\libs',
             'file: C:\project\subProjectThree\libs',
            ]

```
