Provided dependencies

How to exclude some dependencies / ensure that it will be not wrapped?

I included some compile dependency which is dependant of slfj-api. Dependency is being automatically wrapped and deployed as bundle.

But in one of my projects, I also want to use slf4j, and I added compile dependency to it. After that I have two bundles slf4j deployed on instance. How to prevent such situation?

I has also problem with wrapping javax.inject . Yes I know there exist such bundle, but in my lib it is not referenced artifact which is a bundle.

Unable to wrap javax.inject-1.jar

how to prevent wrapping it?

[renatoathaydes]

When you declare the dependency that imports slf4j, exclude the transitive dependency on slf4j as follows:

dependencies {
    compile "your:actual-dependency:1.0", {
        exclude group: 'org.slf4j'
    }
}

This should work. If not, let me know.

Here's an example build file from another of my projects that excludes some transitive dependencies:

The problem wrapping javax.inject is due to it apparently not having a manifest at all!? I will fix the code so it won't break, but it's strange that a jar doesn't have any manifest... not sure that's even a valid jar.

[renatoathaydes]

@pun-ky release 1.4.2 fixes the problem you had with javax.inject. It will still emit a warning because it's not normal for a jar to not have a jar.

Notice also that I added a new excludedBundles property which takes a list of regexes which you can use to match against bundle file names to make sure they won't make to the runtime.

For example, in one of my projects I had to add this (because osgi bundles must not be deployed to the runtime, they are provided by the framework already):

runOsgi {
    bundles =
            // uncomment to include the Knopflerfish GUI
            //['org.knopflerfish.bundle:desktop:5.0.1'] +
            ( subprojects as List )

    copyManifestTo 'generated-sources/MANIFEST.MF'

    // required by Groovy
    config += [ 'org.osgi.framework.system.packages.extra': 'sun.reflect' ]

    // no OSGi framework bundles should be deployed
    excludedBundles = [ /osgi\..*/ ]
}
