# Maven API

This is the API documentation for [Maven Packages](../../user/packages/maven_repository/index.md).

WARNING:
This API is used by the [Maven package manager client](https://maven.apache.org/)
and is generally not meant for manual consumption.

For instructions on how to upload and install Maven packages from the GitLab
package registry, see the [Maven package registry documentation](../../user/packages/maven_repository/index.md).

NOTE:
These endpoints do not adhere to the standard API authentication methods.
See [Maven package registry documentation](../../user/packages/maven_repository/index.md)
for details on which headers and token types are supported.

## Download a package file at the instance-level

> Introduced in GitLab 11.6.

Download a Maven package file:

```shell
curl --header "Private-Token: <personal_access_token>" "https://gitlab.example.com/api/v4/packages/maven/foo/bar/baz/mypkg-1.0-SNAPSHOT.jar"
```

To write the output to file:

```shell
curl --header "Private-Token: <personal_access_token>" "https://gitlab.example.com/api/v4/packages/maven/foo/bar/baz/mypkg-1.0-SNAPSHOT.jar" >> mypkg-1.0-SNAPSHOT.jar
