Please publish the source jar with OSGI manifest headers, too

[15knots]

The implementation jar of sshj on maven central already has proper OSGI manifest headers, which makes it easy to put that jar into a p2 repository to use sshj as an Eclipse bundle.

But the source jar does not have the appropriate OSGI manifest headers. If one puts the source jar into a p2 repository for use in a target platform, the Eclipse IDE will not find and show the Java sources when debugging.

I am willing to help with this, but I do not know gradle (only maven).

[hierynomus]

@15knots Could you check whether a clean build now produces the correct OSGI manifest headers for the sources.jar?

[15knots]

Thanks for the quick response, first.

Sorry, neither my local build nor the 0.16.0 version on maven central has the proper manifest headers.
See this real-life example of those MANIFEST.MF headers :

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Razorcat Application Server client API Source
Bundle-SymbolicName: com.razorcat.appserver.client.api.source
Bundle-Version: 1.1.2
Eclipse-SourceBundle: com.razorcat.appserver.client.api;version="1.1.2 ";roots:="."

In the above,

• Bundle-Name is the name of the corresponding binary bundle plus ' Source'. This name is shown in the Eclipse 'Edit Target Wizard'.
• Bundle-SymbolicName is the same as in the binary bundle plus '.source' (by convention). This is displayed in the content tab of the 'Edit Target Wizard'.
• Bundle-Version should match the one of the binary bundle.
• Eclipse-SourceBundle marks the bundle as the source bundle. See Eclipse-SourceBundle for details.
• For source bundles, no other export/import OSGI manifest headers are required.

For builds with maven, I simply use the archive manifestEntries elements to set the required headers when generating the source bundle jar:

<archive>
  <manifestEntries>
     <Bundle-ManifestVersion>2</Bundle-ManifestVersion>
     <Bundle-Name>${project.name} Source</Bundle-Name>
     <Bundle-SymbolicName>${project.groupId}.${project.artifactId}.source</Bundle-SymbolicName>
     <Bundle-Version>${parsedVersion.osgiVersion}</Bundle-Version>
     <Eclipse-SourceBundle>${project.groupId}.${project.artifactId};version="${parsedVersion.osgiVersion}";roots:="."</Eclipse-SourceBundle>
     <Bundle-Vendor>${project.organization.name}</Bundle-Vendor>
  </manifestEntries>
</archive>

Thanks. I'll fix this for the next release!

Please PM me an URL for beta-testing that prior to releasing it.
I will then test

• how the jars get incorporated into a p2 repo and
• how that p2 repo looks in a p2 repo browser (e.g. Eclipse target editor).
  I´m a little concerned here, the 0.16.0 release might have broken something for p2 users.

Just committed 317bbfa on branch https://github.com/hierynomus/sshj/tree/issue-242

Can you build that branch and see whether the manifest looks better now?

[15knots]

Wow,

BUILD SUCCESSFUL
Total time: 49 mins 44.204 secs

It still has the Im-/Export headers.
I improved it (non-working, commented patch issue-242-1.patch.txt), but could not solve due to my lack of knowledge in gradle.

With the patch, it looks better,


but that does not solve this issue due to problems generating a proper version number.

[hierynomus]

Thanks, will have a look!

Got it!

task sourcesJar(type: Jar) {
    classifier = 'sources'
    from sourceSets.main.allSource
    manifest { // manifest is NOT of type OsgiManifest
        attributes(
           "Bundle-ManifestVersion": "2",
           // copy values from binary jar manifest to be consistent...
           "Eclipse-SourceBundle": project.jar.manifest.getSymbolicName()
            + ";version=\"" + project.jar.manifest.getVersion() + "\";roots:=\".\"",
           "Bundle-SymbolicName": project.jar.manifest.getSymbolicName() + ".source",
           "Bundle-Version": project.jar.manifest.getVersion()
           "Bundle-Name": project.jar.manifest.getName() + " Source",
        )
    }
}

Please carefully review, I'm a gradle newbie.

Gives

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Eclipse-SourceBundle: com.hierynomus.sshj;version="0.16.1.dev_1_uncomm
 itted_317bbfa";roots:="."
Bundle-Name: sshj Source
Bundle-SymbolicName: com.hierynomus.sshj.source
Bundle-Version: 0.16.1.dev_1_uncommitted_317bbfa

Eclipse target definition looks good, target content the same and the eclipse editor is showing the source.

[hierynomus]

Fixed it, thanks for looking at it. Do you need an 0.16.1 release with the fixed manifests?

[15knots]

Yes, please release 0.16.1

Plus you could mention in the README, that sshj now has proper manifest headers for OSGI and is ready for incorporation into a p2 repo. That way, it can be used to build Eclipse bundles.
