Add a publish-gradle job to the release workflow to publish Processing libraries to the Gradle Plugin Portal.

This way future processing libraries can be created by adding

plugins{
    id("org.processing.library") version "4.5.3"
}

processing {
    library {
        version = 1
        prettyVersion = "1.0.0"

        authors = mapOf(
            "The Processing Foundation" to "https://processing.org"
        )
        url = "https://processing.org/"
        categories = listOf("file", "exporter", "dxf")

        sentence = "DXF export library for Processing"
        paragraph =
            "This library allows you to export your Processing drawings as DXF files, which can be opened in CAD applications."

    }
}

To any standard Java/Kotlin gradle project, this will then handle packaging the library. We can add more functionality to it over time and the only thing library authors will need to do is update the plugin version.

TODO:

  • Create Gradle Portal Account (account created with the processing-bot)
  • Set repository secrets (GRADLE_PUBLISH_KEY, GRADLE_PUBLISH_SECRET)

After merge:

  • Update the processing gradle library template

Publish Processing Gradle plugin
f46bd75 
Add a publish-gradle job to the release workflow to publish Processing libraries to the Gradle Plugin Portal using gradle publish with required secrets and version/group env vars. Update gradle/plugins/library/build.gradle.kts to use the com.gradle.plugin-publish plugin, provide plugin metadata (website, vcsUrl, displayName, description, tags) and make the plugin id dynamic ("$group.library"). These changes enable automated publishing of the Gradle plugin with the metadata required by the portal.

Set project.group system property for tests
8b0cdaf 
Expose the project's group to test JVMs by configuring tasks.withType<Test>() to set systemProperty("project.group", group ?: "org.processing"). Update ProcessingPluginTest to read the plugin id from System.getProperty("project.group") instead of hardcoding the group. Also close the publishing block in build.gradle.kts. This allows tests to adapt when the project group is overridden.
