extends ProjectPlugin

Now that Eclipse is publishing artifacts to maven central, it’s possible to use the valuable components of the eclipse project without getting bogged down in p2 and OSGi.

The trouble is that it can be difficult to get a coherent set of versions across the many bundles. It’s also a little tricky to know what the groupId:artifactId mapping is, since eclipse artifacts only have a bundleId by default.

Here is the fix:

apply plugin: 'com.diffplug.eclipse.mavencentral'
eclipseMavenCentral {
    release '4.7.0', {
        // supports the standard java configurations
        api 'org.eclipse.swt'
        implementation 'org.eclipse.jdt'
        testImplementation 'org.eclipse.swt'
        // and custom ones too
        dep 'implementation', 'org.eclipse.jdt'
        // specify this to add the native jars for this platform
        useNativesForRunningPlatform()
        // specify that all transitive dependencies should be from this release
        // (otherwise the version ranges which eclipse uses will use latest available)
        constrainTransitivesToThisRelease()
    }
}

Platform-native jars

When an eclipse jar needs a platform-specific dependency, such as SWT, the platform-specific part of the name is specified in the POM as ${osgi.platform}. useNativesForRunningPlatform() will replace ${osgi.platform} with whatever is appropriate for your platform, such as org.eclipse.swt.win32.win32.x86_64.

That’s normally all you need, but if you want more specific control, there is a special sourceSetNative method, along with builtins like testRuntimeNative for each of the builtin java configurations.

eclipseMavenCentral {
    release '4.7.0', {
        testRuntimeOnlyNative 'org.eclipse.swt'
        nativeDep 'testRuntimeOnly', 'org.eclipse.swt'
    }
}

Either of the above lines will add the org.eclipse.swt.win32.win32.x86_64 as a testRuntimeOnly dependency if you’re running on a 64-bit JVM on Windows, or some whichever platform-specific jar is appropriate. This works only for the SWT naming convention, windowing.os.arch.

Compatibility

Only works with versions from 4.6.2 onwards.
