Flatpak

Flatpak is a framework for distributing desktop applications across various Linux distributions. It has been created by developers who have a long history of working on the Linux desktop, and is run as an independent open source project.

We recommend reading the Upstream Metadata and the Flatpak manifest documentation as Flatpak depends on them.

The following artifact extensions are supported by this packager:

.tgz
.txz
.tar.gz
.tar.xz
.tar
.zip

Substitute ${name} for the value of the named instance.

Space (' '), underscore (_), and dash (-) will be replaced by dot (.) to separate tokens in the System property. Space (' '), dash (-), and dot (.) will be replaced by underscore (_) to separate tokens in the environment variable, such that:

${name} System Property Environment Variable

${name}	System Property	Environment Variable
foobar	`foobar`	`FOOBAR`
fooBar	`foobar`	`FOOBAR`
foo bar	`foo.bar`	`FOO_BAR`
foo-bar	`foo.bar`	`FOO_BAR`
foo_bar	`foo.bar`	`FOO_BAR`
foo.bar	`foo.bar`	`FOO_BAR`

Tokens

The repository token environment variable must match with the chosen Release service.

On GitHub, you can’t use the default secrets.GITHUB_TOKEN as this token only works for the repository that’s running the workflow. You must configure a Personal Access Token (PAT) instead. It is recommended that you use "fine-grained" PATs, rather than "classic" ones. The token must have:

Access to your tap repository; if this repository is part of a GitHub organization, make sure to choose that organization as the resource owner; if that organization doesn’t show up in the "resource owner" drop-down, contact your organization adminstrator and ask them to enable PAT access for that repository
The "Contents read and write" repository permission

DownloadURL

JReleaser follows these rules to find the download URL to use for a given artifact:

if artifact.extraProperties.flatpakDownloadUrl exists, use it.
if artifact.extraProperties.downloadUrl exists, use it.
if explicit downloadUrl is set on flatpak, use it.
if distribution.extraProperties.flatpakDownloadUrl exists, use it.
if distribution.extraProperties.downloadUrl exists, use it.
if releaser.${release}.skipRelease is false then use the releaser’s downloadUrl.
if releaser.${release}.skipRelease is true then look for a matching uploader given an extraProperty named downloadUrlFrom on artifact, distribution, `flatpak (in that order). The value must be <uploaderType>:<uploaderName> such as "artifactory:app" or "s3:uploads".
fail if no suitable URL is found.

With no extra configuration from your side rule 6. will be chosen which is the suitable default that most projects need.

Icon

You must define at least one icon. A square (256x256 pixels) image in PNG format is preferred.

Skip Screenshots

You may add a skipFlatpak extra property to a target screenshot to mark it as skipped for packaging with Flatpak.

Skip Icons

You may add a skipFlatpak extra property to a target icon to mark it as skipped for packaging with Flatpak.

Templates

The default location for templates is:

src/jreleaser/distributions/<distribution-name>/flatpak

The following list shows the filenames that may be used to override default templates:

cli-app.yml.tpl
cli-metainfo.xml.tpl
desktop-app.desktop.tpl
desktop-app.yml.tpl
desktop-metainfo.xml.tpl
flathub.json.tpl
README.md.tpl

Any additional files found in the template directories will be copied as is unless their filename ends with .tpl in which case Name Templates substitution will take place.

Templates may be initialized using the template command

Skip Templates

You may skip any template files by defining a set of skip rules in the skipTemplates property. For example, you may use any of these expressions to skip a template named README.md.tpl:

README.md.tpl: matches the full template name
README.md: matches the transformed template name
README.*: matches using a regex

Skip Artifacts

If there is more than one matching artifact in a given distribution you may add a skipFlatpak extra property to the target artifact to mark it as skipped for packaging with flatpak.

Skip License

If there’s a matching LICENSE file available at the root of the project it will be copied to the repository by default. You may set an extra property named skipLicenseFile on flatpak to skip this behavior.

Publication to Flathub

Flathub is the home of hundreds of apps which can be easily installed on any Linux distribution.

You are responsible for submitting a ticket to Flathub for adding a new app. JReleaser does not create a ticket nor a pull request for you. However, once your application has been accepted to Flathub you may update the flatpack configuration to point to the appointed repository.

Please consult the App Submission to know more.

Repository

The repository section allows setting extra properties that may be used to provide additional hints when interacting with the git repository that holds packager files.

GitLab

Define a projectIdentifier property to directly locate the project associated with the repository, such as

YAML
TOML
JSON
Maven
Gradle

packagers:
  flatpak:
    repository:
      extraProperties:
        projectIdentifier: 12345678

[packagers.flatpak]
  repository.extraProperties.projectIdentifier = "12345678"

{
  "packagers": {
    "flatpak": {
      "repository": {
        "extraProperties": {
          "projectIdentifier": "12345678"
        }
      }
    }
  }
}

<jreleaser>
  <packagers>
    <flatpak>
      <repository>
        <extraProperties>
          <projectIdentifier>12345678</projectIdentifier>
        </extraProperties>
      </repository>
    </flatpak>
  </packagers>
</jreleaser>

jreleaser {
  packagers {
    flatpak {
      repository {
        extraProperties.put("projectIdentifier", "12345678")
      }
    }
  }
