Hi guys, I’m trying to make an application with gradle and grails. My problem is that I would like to make the project available offline, but if I comment out the maven { url “[https://repo.grails.org/grails/core](https://repo.grails.org/grails/core)” } line I get a build error, but if the line is left uncommented it works. I have a local maven repository and I believe everything is cached there already, so how could I make it work wothout the online repository?

Thanks.

Do you have `mavenLocal()` configured?

```gradle
repositories {
   mavenLocal()
}

```

Yes I, have that line, but should I do something else as well?  
and I have C:/Programs/maven-repository in my settings.xml

Perhaps you need

```gradle
maven {
   url uri('C:/Programs/maven-repository')
}

```

There’s also the `--offline` flag at the command line to use the gradle cache  
There’s also [this gist](https://gist.github.com/bmuschko/e4e04abca105c397145e) which can store project dependencies on the local file system

Thanks, I have tried out your fix but I got a lot of error messages, which I have included  
The error messages:

</div>

So my problem is, that if I use  
maven {  
url “[https://repo.grails.org/grails/core](https://repo.grails.org/grails/core)”  
//url uri(‘C:/Programs/maven-repository/’)  
}  
the URL it works, but if I comment it out and try to use the local version I get a lot of errors, but the grails website works, even offline because I have it cached on the system.

Have you tried

1. Running a normal build (to prep gradle’s cache)
2. Running a second build passing `--offline` at command line?

</div>

Thank I have tried it out it really works if I use the --offline parameter, but the problem is that it is using the cache, but the project I am working on requires that I can put the libraries under configuration management, so I have to make sure that, the project doesn’t use the cache, only the available maven-repository (in my case under C:\Programs).  
So is there a way I can make the project to run only from the local repository without the cache?

You could use [this gist](https://gist.github.com/bmuschko/e4e04abca105c397145e) to backup your dependencies and then reference them via

```gradle
maven {
   url uri('c:/path/to/offline/dependencies')
}

```

Yes, I have tried the gist, but it doesn’t copy everything because when I try to run it, I get errors saying that I don’t have a specific files at the path. So could it be that the gist doesn’t backup all the dependecies?

Maybe the problem is that I didn’t include all the necessary dependencies into the gradle script.

Ah… looks like you need to take a copy of the buildscript classpath configuration too.  
Note that the OfflineMavenRepository accepts a `configurationName` parameter and looks it up via project.configurations.getByName(…). You’ll need to tweak it to accept a `Configuration` object instead of a string. Then you could do:

```gradle
task exportRuntime(type: OfflineMavenRepository) {
   configuration = configurations.runtime
   repoDir = file('/path/to/repo')
}
task exportBulidscriptClasspath(type: OfflineMavenRepository) {
   configuration = buildscript.configurations.classpath
   repoDir = file('/path/to/repo')
}

```

Or perhaps

```gradle
task exportBoth(type: OfflineMavenRepository) {
   configurations = [buildscript.configurations.classpath, configurations.runtime]
   repoDir = file('/path/to/repo')
}

```

Note: You’ll also need to declare the file path in your `buildscript {}` block when working offline

```gradle
buildscript {
    repositories {
        maven { 
           url uri('c:/path/to/offline/dependencies')
        }
    }
}

```

Thanks, with the two export tasks it finally downloaded the core libraries, but it still can’t find the libs.  
I have this in my buildscript: where offline-repo is the directory where the previous tasks downloaded the libraries. Should I give a different path to it?

> buildscript {

</div>

Are using the new or old syntax to declare `org.grails:grails-gradle-plugin:3.1.4`?

If you are using the “new” plugin syntax, you will have to add the following to settings.gradle

```gradle
pluginRepositories {
  maven {
    url uri('C:/workspace/offline/build/offline-repo')
  }
}

```

If you are using the “old” plugins syntax you will need to add the following to build.gradle

```gradle
buildscript {
   repositories {
      maven {
         url uri('C:/workspace/offline/build/offline-repo')
      }
   }
}

```

In both cases, you’ll also need a repository declaration for the normal dependencies

```gradle
repositories {
   maven {
      url uri('C:/workspace/offline/build/offline-repo')
   }
}

```

Thank you, I really appreciate your help, but it still doesn’t work. ☹ I checked the files, and they are there, maybe the problem is that it is looking for the files at:

> C:/workspace/offline/build/offline-repo/org/grails/grails-gradle-plugin/3.1.4/grails-gradle-plugin-3.1.4.pom

but they are actually at:

> C:/workspace/offline/build/offline-repo/org.grails/grails-gradle-plugin\3.1.4/grails-gradle-plugin-3.1.4.pom

I don’t really know if it could be the problem or not.

Also if I enable the online repositories, gradle says

> configurations = [configurations.testRuntime, buildscript.configurations.classpath]

line is problematic: Cannot get property ‘testRuntime’ on null object

Looks like you’ll need to tweak the `copyJars` and `copyPoms` methods to replace dots with slashes in the group

eg change:

`File moduleDir = new File(repoDir, "${moduleVersionId.group}/...")`  
to  
`File moduleDir = new File(repoDir, "${moduleVersionId.group.replace('.', '/')}/...")`

> Also if I enable the online repositories, gradle says  
> configurations = [configurations.testRuntime, buildscript.configurations.classpath]  
> line is problematic: Cannot get property ‘testRuntime’ on null object

Ah, that’s because the `configurations` task parameter is overriding `project.configurations`… try this instead:  
`configurations = [project.configurations.testRuntime, buildscript.configurations.classpath]`
