JBang

Unleash the power of Java with jbang. You can publish distributions as JBang catalogs.

Each separate executable will have its own JBang script. All executables will be collected in the same catalog. Existing catalogs located at the target repository will be merged into a single catalog.

Publications of snapshots is supported, in which case executables will bear the -snapshot suffix in their alias.

You must define a value for java.mainClass in the owning distribution.
When the project’s version is snapshot, unless manually updated, the default prepared template assumes JARs may be resolved from https://jitpack.io.
Aliases must be unique!

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

foobar

foo.bar

FOO_BAR

Example

Assuming the current version is 1.2.3, and a distribution named app, the above configuration will generate a app.java file in the duke/jbang-catalog repository:

jbang-catalog.json
{
  "aliases": {
    "app": {
      "script-ref": "app.java",
      "description": "Sample app"
    }
  }
}
app.java
//usr/bin/env jbang "$0" "$@" ; exit $?
//JAVA 8
//DEPS com.acme:app:1.2.3

public class app {
    public static void main(String... args) throws Exception {
        com.acme.Main.main(args);
    }
}

When the version is snapshot then the catalog and the script template change to:

jbang-catalog.json
{
  "aliases": {
    "app-snapshot": {
      "script-ref": "app_snapshot.java",
      "description": "Sample app"
    }
  }
}
app_snapshot.java
//usr/bin/env jbang "$0" "$@" ; exit $?
//JAVA 8
//REPOS jitpack
//DEPS com.github.duke:app:main-SNAPSHOT

public class app_snapshot {
    public static void main(String... args) throws Exception {
        com.acme.Main.main(args);
    }
}

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

Templates

The default location for templates is:

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

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

  • jbang.java.tpl

  • jbang-catalog.json.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 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 jbang to skip this behavior.

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:
  jbang:
    repository:
      extraProperties:
        projectIdentifier: 12345678
[packagers.jbang]
  repository.extraProperties.projectIdentifier = "12345678"
{
  "packagers": {
    "jbang": {
      "repository": {
        "extraProperties": {
          "projectIdentifier": "12345678"
        }
      }
    }
  }
}

      </repository>

</jreleaser>
jreleaser {
  packagers {
    jbang {
      repository {
        extraProperties.put("projectIdentifier", "12345678")
      }
    }
  }
}
