An sbt plugin for missinglink.

Add the following line in project/plugins.sbt:

addSbtPlugin("ch.epfl.scala" % "sbt-missinglink" % "0.2.0")

the simply run the following task for the project you want to test:

> theProject/missinglinkCheck

This will check that the transitive dependencies of your project do not exhibit any binary compatibility conflict, assuming that the methods of your Compile configuration (in src/main/) are all called.

You can test another configuration, such as Test or Runtime, with:

> theProject/Runtime/missinglinkCheck

By default, the plugin fails the build if any conflicts are found. It can be disabled by the missinglinkFailOnConflicts setting:

missinglinkFailOnConflicts := false

Conflicts can be ignored based on the package name of the class that has the conflict. There are separate configuration options for ignoring conflicts on the "source" side of the conflict and the "destination" side of the conflict. Packages on the source side can be ignored with missinglinkIgnoreSourcePackages and packages on the destination side can be ignored with missinglinkIgnoreDestinationPackages:

missinglinkIgnoreDestinationPackages += IgnoredPackage("com.google.common")
missinglinkIgnoreSourcePackages += IgnoredPackage("com.example")

By default, all subpackages of the specified package are also ignored, but this can be disabled by the ignoreSubpackages field: IgnoredPackage("test", ignoreSubpackages = false).

At the moment, compared to the upstream missinglink project, this sbt plugin does not support the following features:

• Excluding some dependencies from the analysis

You can find more information about the problem statement, caveats and limitations, etc. in the upstream project missinglink.
