# Dependency caching
<a name="dependency-caching"></a>

You can enable local caching in CodeBuild to reduce the number of dependencies that need to be fetched from CodeArtifact for each build. For information, see [Build Caching in AWS CodeBuild](https://docs.aws.amazon.com/codebuild/latest/userguide/build-caching.html) in the *AWS CodeBuild User Guide*. After you enable a custom local cache, add the cache directory to your project's `buildspec.yaml` file.

For example, if you are using `mvn`, use the following.

```
cache:
  paths:
    - '/root/.m2/**/*'
```

For other tools, use the cache folders shown in this table.


****  

| Tool | Cache directory | 
| --- | --- | 
|  ** `mvn` **  |  `/root/.m2/**/*`  | 
|  ** `gradle` **  |  `/root/.gradle/caches/**/*`  | 
|  ** `pip` **  |  `/root/.cache/pip/**/*`  | 
|  ** `npm` **  |  `/root/.npm/**/*`  | 
|  ** `nuget` **  |  `/root/.nuget/**/*`  | 
|  ** `yarn (classic)` **  |  `/root/.cache/yarn/**/*`  |
