Bintray Deployment

Travis CI can automatically deploy your build artifacts to Bintray.

All you need to do is add the following to your .travis.yml:

  provider: bintray
  file: "Path to a descriptor file, containing information for the Bintray upload"
  user: "Bintray user"
  key: "Bintray API key"
  passphrase: "Optional. In case a passphrase is configured on Bintray and GPG signing is used"
  dry-run: "Optional. If true, skips sending requests to Bintray. Useful for testing your configuration"

Encrypt your API key

It is recommended that you encrypt your api key. You can encrypt this key using the travis command line client and this command:

$ travis encrypt BINTRAY-API-KEY --add deploy.key

Branch to deploy from

By default, Travis CI will only deploy from your master branch.

You can explicitly specify the branch to deploy from with the on option:

  on: production

Alternatively, you can also configure it to deploy from all branches:

    all_branches: true

Builds triggered from Pull Requests will never trigger a deploy.

Conditional Deploys

You can deploy only when certain conditions are met. See Conditional Releases with on:.

Running commands before and after deploy

Sometimes you want to run commands before or after deploying. You can use the before_deploy and after_deploy stages for this. These will only be triggered if Travis CI is actually deploying.

before_deploy: "echo 'ready?'"
  - ./
  - ./

Descriptor file example

The descriptor is in JSON file format in three sections:

    "package": {
        "name": "auto-upload",
        "repo": "myRepo",
        "subject": "myBintrayUser",
        "desc": "I was pushed completely automatically",
        "website_url": "",
        "issue_tracker_url": "",
        "vcs_url": "",
        "github_use_tag_release_notes": true,
        "github_release_notes_file": "RELEASE.txt",
        "licenses": ["MIT"],
        "labels": ["cool", "awesome", "gorilla"],
        "public_download_numbers": false,
        "public_stats": false,
        "attributes": [{"name": "att1", "values" : ["val1"], "type": "string"},
                       {"name": "att2", "values" : [1, 2.2, 4], "type": "number"},
                       {"name": "att5", "values" : ["2014-12-28T19:43:37+0100"], "type": "date"}]

    "version": {
        "name": "0.5",
        "desc": "This is a version",
        "released": "2015-01-04",
        "vcs_tag": "0.5",
        "attributes": [{"name": "VerAtt1", "values" : ["VerVal1"], "type": "string"},
                       {"name": "VerAtt2", "values" : [1, 3.3, 5], "type": "number"},
                       {"name": "VerAtt3", "values" : ["2015-01-01T19:43:37+0100"], "type": "date"}],
        "gpgSign": false

        {"includePattern": "build/bin(.*)*/(.*\\.gem)", "excludePattern": ".*/do-not-deploy/.*", "uploadPattern": "gems/$2"},
        {"includePattern": "build/docs/(.*)", "uploadPattern": "docs/$1"}
    "publish": true

Package Section

Bintray package information. In case the package already exists on Bintray, only the name, repo and subject fields are mandatory.

  • name is the Bintray package name
  • repo is the Bintray repository name
  • subject is the Bintray subject, which is either a user or an organization

Version Section

Package version information. In case the version already exists on Bintray, only the name field is mandatory.

Files Section

Configure the files you would like to upload to Bintray and their upload path.

You can define one or more groups of patterns. Each group contains three patterns:

  • includePattern: Pattern in the form of Ruby regular expression, indicating the path of files to be uploaded to Bintray.
  • excludePattern: Optional. Pattern in the form of Ruby regular expression, indicating the path of files to be removed from the list of files specified by the includePattern.
  • uploadPattern: Upload path on Bintray. The path can contain symbols in the form of $1, $2,… that are replaced with capturing groups defined in the include pattern.

In the example above, the following files are uploaded:

  • All gem files located under build/bin/ (including sub directories), except for files under a do-not-deploy directory. The files will be uploaded to Bintray under the gems folder.
  • All files under build/docs. The files will be uploaded to Bintray under the docs folder.

Note: Regular expressions defined as part of the includePattern and excludePattern properties must be wrapped with brackets.

Debian Upload

When artifacts are uploaded to a Debian repository on Bintray using the Automatic index layout, the Debian distribution information is required and must be specified. The information is specified in the descriptor file by the matrixParams as part of the files closure as shown in the following example:

    [{"includePattern": "build/bin/(.*\.deb)", "uploadPattern": "$1",
    "matrixParams": {
        "deb_distribution": "vivid",
        "deb_component": "main",
        "deb_architecture": "amd64"}

Overwriting Existing Files

If an artifact by a given name already exists in the Bintray repository, then by default it is not overwritten. If you want to replace the existing file, define the override key in your matrix properties:

    [{"includePattern": "build/bin/(myfile.bin)", "uploadPattern": "$1",
    "matrixParams": {
        "override": 1 }
